ЦитатаApr 01, 2019PSLV-C45/EMISAT MISSIONIndia's PSLV-C45 successfully injected EMISAT and 28 international customer satellites into their designated orbits.The PSLV-C45 lifted off at 09:27 Hrs (IST) on April 01, 2019 from the second launch pad of Satish Dhawan Space Centre SHAR, Sriharikota in its 47th flight. This flight marked the first mission of PSLV-QL, a new variant of PSLV with four strap-on motors.About 17 minutes and 12 seconds after lift-off, EMISAT was successfully injected into intended sun-synchronous polar orbit of 748 km height.After the separation of EMISAT, the vehicle's fourth stage engines were restarted twice to place the 28 international customer satellites precisely into a sun-synchronous orbit of 504 km height. The last customer satellite was placed in its designated orbit 1 hour and 55 minutes after lift-off.About 3 hours after lift-off, the fourth stage (PS4) of the vehicle was moved to a lower circular orbit of 485 km after two restarts to establish it as an orbital platform for carrying out experiments with its three payloads. The PS4 payloads are Automatic Identification System from ISRO, Automatic Packet Repeating System from AMSAT, India and Advanced Retarding Potential Analyzer for ionospheric studies from Indian Institute of Space Science and Technology.
ЦитатаApr 01, 2019PSLV-C45 successfully launches EMISAT and 28 customer satellitesIndia's Polar Satellite Launch Vehicle (PSLV-C45) today successfully launched EMISAT and 28 international customer satellites from Satish Dhawan Space Centre (SDSC) SHAR in Sriharikota. This flight marked the first mission of PSLV-QL, a new variant of PSLV with four strap-on motors.PSLV-C45 lifted off at 9:27 Hrs (IST) from the Second Launch Pad and injected India's EMISAT into a 748 km sun-synchronous polar orbit, 17 minutes and 12 seconds after lift-off. After separation, the two solar arrays of EMISAT were deployed automatically and the ISRO Telemetry Tracking and Command Network at Bengaluru assumed control of the satellite. In the coming days, the satellite will be brought to its final operational configuration.Following the separation of EMISAT, the vehicle's fourth stage engines were restarted twice to place the 28 international customer satellites precisely into a sun-synchronous orbit of 504 km height. The last customer satellite was placed into its designated orbit 1 hour and 55 minutes after lift-off.About 3 hours after lift-off, the fourth stage (PS4) of the vehicle was moved to a lower circular orbit of 485 km after two restarts to establish it as an orbital platform for carrying out experiments with its three payloads.EMISAT is a satellite built around ISRO's Mini Satellite-2 bus weighing about 436 kg. The satellite is intended for electromagnetic spectrum measurement.The 28 international customer satellites, together weighing about 220 kg, are from four countries, namely, Lithuania (2), Spain (1), Switzerland (1) and USA (24). These foreign satellites were launched as part of commercial arrangements.The payloads carried by PS4 are Automatic Identification System from ISRO, Automatic Packet Repeating System from AMSAT, India and Advanced Retarding Potential Analyzer for ionospheric studies from Indian Institute of Space Science and Technology.ISRO Chairman Dr K Sivan congratulated the launch vehicle and satellite teams involved in the mission. "Today's PSLV mission was unique in several ways. It was a four strap-on new variant, the vehicle achieved three different orbits and for the first the PS4 stage is powered by solar panels," Dr Sivan said. He added that a new PSLV team executed today's mission.Dr Sivan also placed on record the significant involvement of the industry in this mission.So far, PSLV has launched 46 national satellites, 10 satellites built by students from Indian Universities and 297 international customer satellites, including the satellites launched today. In its next mission, PSLV-C46 will launch RISAT-2B in May 2019.

ЦитатаIndian military satellite, 20 more Planet imaging CubeSats launched by PSLVApril 1, 2019 | Stephen ClarkA 145-foot-tall (44-meter) Polar Satellite Launch Vehicle lifts off fr om the Satish Dhawan Space Center on Monday. Credit: ISROAn Indian Polar Satellite Launch Vehicle blasted off and successfully deployed a military electronic surveillance satellite and 28 nanosatellites for companies in the United States, Lithuania, Spain and Switzerland at two different altitudes Monday, before the rocket's upper stage began an extended mission as a solar-powered experiment platform in low Earth orbit.The 145-foot-tall PSLV lifted off at 0357 GMT Monday (11:57 p.m. EDT Sunday) from the Satish Dhawan Space Center, an Indian spaceport on the country's southeast coast around 50 miles (80 kilometers) north of Chennai.The PSLV is the workhorse rocket for India's space program, launching several times a year, often with an Indian government satellite and a collection of smaller spacecraft built by organizations and companies in other countries.But the mission that launched Monday morning -- liftoff occurred at 9:27 a.m. Indian Standard Time -- debuted a new configuration of the PSLV with four solid rocket boosters mounted around the rocket's core stage. Previous PSLVs launched with zero, two, or six boosters.In another first, the PSLV's liquid-fueled fourth stage carries solar panels to generate electricity in space, providing power to three payloads that will use the spent rocket body as a hosting platform in orbit.The launcher initially headed toward the southeast from the Second Launch Pad at the space center. The four strap-on solid rocket motors burned out and jettisoned around 70 seconds into the mission, followed by burnout and separation of the PSLV's solid-fueled core stage.A hydrazine-fueled Vikas engine on the PSLV's second stage fired next, followed by ignition of the rocket's third stage, a solid-fueled motor. Finally, the PSLV's fourth stage -- known as the PS4 -- fired its twin thrusters, which also burn hydrazine fuel, to place the EMISat spacecraft into an orbit roughly 465 miles (749 kilometers) above Earth, with an inclination of about 98.4 degrees to the equator.The 961-pound (436-kilogram) EMISat satellite, a joint project between the Indian Space Research Organization and India's Defense Research and Development Organization, separated from the PSLV fourth stage around 17 minutes after liftoff. A video camera on the fourth stage showed the EMISat satellite, encased in golden insulation, flying away from the rocket over the Indian Ocean.

Credit: ISRO/Doordarshan TVEMISat carries instrumentation to detect, locate and characterize electromagnetic signals, such as those transmitted by military radars.Two more firings by the PSLV fourth stage maneuvered the rocket into a lower orbit at an altitude of about 313 miles (504 kilometers), and slightly adjusted the orbit's inclination to 97.5 degrees. The maneuvers set up for separation of 28 nanosatellites from companies in the United States, Lithuania, Spain and Switzerland.The CubeSats launched inside spring-loaded modules, and the PSLV commanded the secondary payloads to deploy one-at-a-time over a sequence that concluded just prior to the two-hour mark in the mission.The first nanosatellite to separate from the PSLV's fourth stage was AISTECHSAT 3, a roughly 5-pound (2.3-kilogram) CubeSat for the Spanish company Aistech. The AISTECHSAT 3 nanosatellite is Aistech's second spacecraft to launch into orbit, and will serve as a pathfinder for the company's planned network of satellites providing aviation tracking and remote asset management services.A Lithuanian company named NanoAvionics had two satellites fastened atop the PSLV, and they separated from the rocket next.The first of the NanoAvionics satellites to deploy was M6P, a 15-pound (6.8-kilogram) spacecraft that hosts two commercial payloads for SpaceWorks Orbital and Lacuna Space, two companies designing communications and tracking networks using tiny satellites as relay nodes to collect and retransmit data from devices and sensors around the world.The other NanoAvionics satellite launched was BlueWalker 1. It will test unspecified "patented technologies" in space for AST & Science, a U.S.-based smallsat startup company which acquired a controlling interest in NanoAvionics last year, according to company statements.NanoAvionics announced in February that it was building three low Earth orbit nanosatellites for AST & Science, the first of which is BlueWalker 1. The three nanosatellites "will be used to test a range of experimental payloads for defense and commercial customers, and will include a Q/V-band satellite for test and evaluation," NanoAvionics said.NanoAvionics said it took only one month to build the 22-pound (10-kilogram) BlueWalker 1 spacecraft and integrate its payload."The BlueWalker 1 mission demonstrates how NanoAvionics' pre-integrated nano-satellite bus enables faster, more responsive approaches for advancing space technology readiness," said Vytenis Buzas, CEO of NanoAvionics.One of Aistech's CubeSats. Credit: AistechThe second satellite for Astrocast, a Swiss company aiming to build a network of 64 data relay satellites in low Earth orbit, was also launched aboard the PSLV. The shoebox-sized, 8.4-pound (3.8-kilogram) Astrocast 0.2 spacecraft joins Astrocast 0.1, which launched on a SpaceX Falcon 9 rocket in December, to demonstrate the company's concept of using nanosatellites to collect and downlink data from weather buoys, wellhead sensors, pollution monitors and other remote stations.Twenty of the secondary payloads launched on the PSLV-C45 mission are owned by Planet, a San Francisco-based company which operates more than 100 Earth-imaging satellites. Planet's newest 20 Dove nanosatellites, each about the size of a toaster oven, join the company's imaging fleet providing daily views of every location on Earth.Four Lemur-2 CubeSats owned by Spire Global were also aboard the launch, adding to Spire's fleet of more than 70 active nanosatellites tracking ships and collecting atmospheric data that could one day improve the accuracy of weather prediction models.The new batch of Dove CubeSats are part of a group named "Flock 4a" by Planet."Flock 4a will join our current constellation of 100+ Doves, replenishing our on-orbit fleet and furthering our daily global monitoring mission," wrote Mike Safyan, Planet's vice president of launch, in a post on the company's website. "However, these Dove satellites aren't solely for replenishment. They're equipped with the latest technology - upgrades to our imaging chain to improve image sharpness, radiometric consistency, and spectral precision - and push the boundaries of what our on-orbit Doves are capable of."Planet sells its imagery to commercial clients and governments, including U.S. intelligence agencies.The PSLV launch was India's first since the country's military successfully tested an anti-satellite missile Wednesday, destroying an Indian satellite in orbit roughly 175 miles (282 kilometers) above Earth.India's test of a satellite kill vehicle shattered the mission's target, named Microsat-R, into countless fragments. Due to the relatively low altitude of the intercept, most of the material is expected naturally re-enter Earth's atmosphere within days or weeks, but some debris ejected into higher orbits from the force of the impact could remain in orbit longer.Officials from several commercial satellite operators, including Planet, condemned the anti-satellite test."Space should be used for peaceful purposes, and destroying satellites on orbit severely threatens the long-term stability of the space environment for all space operators," Planet said in a statement. "Planet urges all space-capable nations to respect our orbital commons."India's PSLV lifts off Monday with 29 satellites on-board. Credit: ISROSunday night's launch marked the fifth time Planet has put its satellites on an Indian rocket, making Planet one of the Indian space program's biggest export customers.Planet books its rides on PSLV missions with Antrix, the commercial arm of ISRO. For this launch, Planet arranged for its satellites to ride on the PSLV through Spaceflight, a commercial smallsat launch broker based in Seattle.The U.S. Air Force's 18th Space Control Squadron, which detects and catalogs objects in Earth orbit, said in a tweet Friday it is "actively tracking more than 250 pieces of debris associated with (the) Indian ASAT launch" and that the Joint Force Space Component Command is "issuing conjunction notifications to satellite operators as needed to support spaceflight safety."Analytical Graphics Inc. modeled the Indian anti-satellite test, and the company's experts suggested the missile struck the Microsat-R satellite at a relative velocity of nearly 22,000 mph, or 9.8 kilometers per second.AGI's simulation predicted the collision created approximately 6,500 debris fragments larger than a pea, about 0.2 inches in diameter. Experts said fewer objects were expected to be large enough to be tracked by the U.S. military space surveillance radars, meaning much of the debris would remain undetected until it fell back into Earth's atmosphere.Artist's illustration of the solar arrays mounted on the PSLV's fourth stage. Credit: ISROAfter releasing all 29 satellites, the PSLV's fourth stage was programmed to fire its attitude control thrusters to send the rocket into a third orbit about 301 miles (485 kilometers) in altitude, wh ere three experimental payloads mounted to the vehicle were expected to begin their missions.Indian officials used the fourth stage from the previous PSLV launch in January for long-duration experiments in Earth orbit for the first time. On this mission, engineers added solar panels to the fourth stage for increased longevity.The fourth stage carries an Automatic Identification System, or AIS, receiver for ISRO to collect messages from ships, an Automatic Packet Repeater System from AMSAT India to assist amateur radio operators in tracking and monitoring position data, and the Advanced Retarding Potential Analyzer for Ionospheric Studies experiment from the Indian Institute of Space Science and Technology for structural and compositional studies of the ionosphere.

Цитата100th Scottish-built satellite enters orbitBy Kenneth MacdonaldBBC Scotland Science Correspondent2 hours agoFour Lemurs were aboard the Indian Space Research Organisation's PSLV-C45 rocketThe data company Spire Global has announced the launch of its 100th Glasgow-built satellite.The Low Earth Multi-Use Receiver (Lemur) satellites are designed to gather data on shipping, weather and aircraft.The company, which is headquartered in San Francisco, says it already has the world's largest constellation of Earth observation satellites.It plans to have 175 of them in low Earth orbit.Each Lemur is based on the small CubeSat design.The basic unit is a 10cm cube - a litre of instrumentation. The Lemur is a so-called 3U design - a stack of three such cubes.That's not much more than the volume of an extra-large bottle of supermarket cola, but miniaturisation means a lot of sensor power can be crammed into a small space.The satellites are shot into their correct positions from a rocketIt also means a satellite that can piggyback on a rocket carrying a larger payload into orbit, cutting launch costs.The latest launch carried four Lemurs aboard the Indian Space Research Organisation's PSLV-C45 rocket.Once in space, the CubeSats made their final leap to orbit from a deployer built by the American company Nanoracks.Its basic principle is simple: the satellites are shot into their correct positions by a spring mechanism like an orbital jack in the box.Spire Global styles itself as a space data analytics company rather than a satellite builder.It uses its satellites to gather information from parts of the world which can be difficult to monitor.They harvest weather data from otherwise remote regions and track ships and their cargoes sailing far beyond the reach of coastal radar. They can also track aircraft.Control risksThe resulting datasets are quickly made available to customers across the world.They are marketed to shipping and insurance companies wanting to control risks, and to coastguards and other agencies fighting piracy and illegal fishing.Spire chose Glasgow as its European base because of the city's existing expertise in space technology.The first Scottish-built satellite was UKube-1, a 3U CubeSat built for the UK Space Agency and launched in 2014.It was assembled in Glasgow by Clyde Space, which has now been bought by the Swedish space company AAC. Clyde Space continues to be a major player in the market for CubeSat components.Scotland has a burgeoning space tech sector which has created thousands of jobs and now more than 100 satellites.Other firms are planning more satellites and launch vehicles.But there are already more Glasgow-built satellites in orbit than from any other city in Europe.
ЦитатаAstrocast Successfully Launches Second Test NanosatelliteSatellite Tests Clean Propulsion Technologies for Rapid Separation, Collision Avoidance, and De-OrbitingAstrocast Launches Mission Hawaii (Graphic: Business Wire)April 01, 2019 06:00 AM Eastern Daylight TimeLAUSANNE, Switzerland-- (BUSINESS WIRE)--Astrocast announced today the successful launch of its second IoT Nanosatellite. The launch, piloted by Indian Space Research Organization (ISRO) on its Polar Satellite Launch Vehicle (PSLV), took place yesterday from the Satish Dhawan Space Center. This second mission will offer more opportunities to customers interested in testing the Astrocast IoT communication services. This mission will also focus on a set of propulsion technologies designed for separation, collision avoidance and de-orbiting. Скрытый текст: "It is very important that companies think about the entire lifecycle of their nanosatellites. As a Swiss company, we will lead by example and do everything we can to keep space clean. Using a set of reliable and flight proven technologies, Astrocast is building the ability to control, maneuver and ultimately de-orbit its satellites," said Fabien Jordan, CEO of Astrocast. "We can avoid collisions from other satellites, easily de-orbit and re-deploy satellites for technology upgrades, and reduce the amount of space debris left at the end of a satellite's lifecycle. This nanosatellite represents the first of many technology advances we aim to develop toward the security and longevity of our network."The ability to control, reposition and de-orbit nanosatellites is key to lessening the amount of space debris that is currently plaguing low-earth orbit missions. Collision avoidance is an ongoing battle. Astrocast is the first to test a series of technologies that will allow them to have greater control and maneuverability of their network once it is launched. These technologies include:[/li]Gas propulsionElectric propulsionAutomatic de-orbitingBackup communications"It is important that companies begin to think long term about the nanosatellites they launch into orbit. Clean nanosatellite technology is possible, and we are taking some of the first steps toward this," Jordan said.This is the second test of the Astrocast IoT Nanosatellite network. The first test, launched in December, is fully stabilized with a working payload and is operating nominally. Astrocast is a nanosatellite network of 64 CubeSats specifically designed to transmit and receive low bandwidth data from IoT devices. Astrocast will be the first nanosatellite solution to deliver all of these features:[/li]100% coverage of the globe including remote areasLowest latency low earth orbit networkTwo-way communicationsL-Band and S-Band frequenciesCommunication module smaller than a credit card designed in partnership with Airbus256 bit encryption with multi-level securityPatented data protocol developed and optimized for satellite IoTLow-cost and ultra-low power chipset optimized for AstrocastMiniaturized antennaLow-cost data plansWeb application for monitoring assets and subscription plan.About AstrocastAstrocast SA, in partnership with the European Space Agency, Airbus, and Thuraya, is developing an advanced nanosatellite network for the Internet of things (IoT). Airbus and Astrocast have developed a low-cost ASIC and module that provides the most power efficient satellite modem for IoT applications. The constellation will consist of 64 CubeSat satellites in Low Earth Orbit (LEO) and will provide low latency global coverage. Astrocast was founded in 2014 by the developers of SwissCube, one of the longest lasting, operational nanosatellites in space. For more information visit www.astrocast.com.

That's a bit odd, was expecting one object (PSLV PS4) in a 435 x 435 km orbit. Possibly final RCS burn did not happen, and a debris object came off.

ЦитатаJonathan McDowellПодлинная учетная запись @planet4589 16:22 PDT - 3 апр. 2019 г.Three more objects cataloged today: 44106 and 44107 are GTO debris objects from the Centaur AV-049 breakup and 44109 is another object from the PSLV launch, in the same low orbit as the 4th stage16:23 PDT - 3 апр. 2019 г.This means that we now have the right number of objects being tracked from the PSLV launch, but two of them are not in the orbit they were expected to be in (deploy hang?)
ЦитатаT.S. Kelso @TSKelso 2 ч. назадCelesTrak has now identified all 30 objects from the PSLV-C45 launch, with input from @SpireGlobal on their 4 satellites and @HAMSATNL on M6P. That made BLUEWALKER 1 #44105, by process of elimination. https://celestrak.com/NORAD/elements/tle-new.php ...
ЦитатаTwo NanoAvionics Satellites were Launched with PSLV-C45, Communications Established Successfully Press Releases 2019-04-08After the last week's lift-off of the PSLV-C45 launch vehicle with two NanoAvionics nano-satellites, "M6P" and "Blue Walker 1", onboard, the company is pleased to confirm that the communication was successfully established with both satellites and they are flying in the Low Earth Orbit in a healthy condition."M6P" and "Blue Walker 1" were launched from the India Space Research Organization's Satish Dhawan Space Center on April 1 (03:57 UTC) with the PSLV-C45 launch vehicle, which rose to a 749-kilometer polar orbit and deployed the primary payload, the Indian government's own EMISAT. Eighty-three minutes later, the PSLV-C45 began deploying the remaining 28 small satellites, including "M6P" and "Blue Walker 1." NanoAvionics' mission operation control center established two-way communication with "M6P" on the 2nd of April 11 am UTC and with "Blue Walker 1" on 3rd of April 5 pm UTC. The telemetry data and information from NORAD indicates that both satellites were ins erted into a lower orbit than it had been expected, due to currently unknown reasons which are under investigation. Delayed separation from the 4th stage of PSLV caused delays in the initial commissioning of "M6P" and "Blue Walker 1" and also slightly reducing the expected orbital lifetime of both satellites. The impact of the anomaly on the mission is currently under evaluation.Currently, both nano-satellites are in the commissioning stage. NanoAvionics will operate "M6P" and "Blue Walker 1" for the full length of their missions, further benefiting its customers.NanoAvionics "M6P" is a ride-share mission which hosts payloads from two Internet of Things (IoT) communication companies. SpaceWorks Orbital and Lacuna Space are each developing satellite-based communication systems for a new generation of low-power IoT devices."BlueWalker 1" is used for testing AST & Science patented technologies in space. The "BlueWalker 1" is the first of three nano-satellites that AST & Science plans to deploy over the course of eighteen months. The two companies are partnering to take advantage of NanoAvionics' best-in-class buses, power systems, and services for this and subsequent AST & Science missions.The large payload volume of NanoAvionics M6P bus, up to 5U, can support small payloads from multiple customers. By sharing an M6P bus's up to 5U payload volume, project teams can divert resources to other essential tasks. Also, the rideshare service relieves the burden of launch integration and logistics, frequency allocation, and satellite operation while it's in orbit for NanoAvionics customers. The M6P bus's standardized hardware and software interfaces accelerate the satellite integration timeframe by several times as well as help to define an interface for payloads."Two NanoAvionics nano-satellites, both based on the company's flagship multipurpose satellite bus and carried on the PSLV-C45, demonstrate great team-work and the val ue of our design approach," NanoAvionics CEO Vytenis J. Buzas said. "We help our customers accelerate their development cycles with rapid integration and more frequent shared payload opportunities. "Blue Walker 1" was manufactured, tested, and launched in less than three months, which is a real manifestation of the new space ideology".ABOUT NANOAVIONICS:NanoAvionics is a nano-satellite bus manufacturer and mission integrator. Its flagship multi-purpose M6P is the first preconfigured nano-satellite Bus in the sector, designed to serve emerging commercial space markets. The company's efforts are focused on enabling critical satellite functions and optimizing their launch, hardware and operation costs - ranging from single missions to constellations.
