More than three years after its launch was delayed by a corporate merger, a commercial Earth-imaging satellite has finally shipped to its California rocket base for liftoff aboard an Atlas 5 in September.
The WorldView 4 spacecraft, built by Lockheed Martin, was moved this week from its factory in Sunnyvale to Vandenberg Air Force Base located a few hours to the south.
Liftoff of the United Launch Alliance Atlas 5 rocket is planned for Sept. 15 at 11:30 a.m. local (2:30 p.m. EDT; 1830 GMT) from the SLC-3E pad on South Base. The day's launch window will remain open for 14 minutes.
Operated by DigitalGlobe of Westminster, Colorado, the sharp-eyed satellite will circle 383 miles above the Earth in polar orbit and snap high-resolution pictures of the world below for customers including the U.S. government, agriculture, oil and gas, scientific researchers and land developers.
But the launch has been on hold for over three years, delaying the original deployment date planned for the spring of 2013. That's because former competitors GeoEye and DigitalGlobe merged their operations and independent fleets of imaging satellites into one company.
While both firms were developing state-of-the-art satellites for launch before the corporate marriage, the new company opted to launch DigitalGlobe's WorldView 3 satellite first since it also provided multiple short-wave infrared bands that could penetrate haze, fog, dust, smoke and other air-born particulates.
That left GeoEye's bird on the ground to await market demand for its launching to effectively double DigitalGlobe's high-resolution imagery collection capacity. The craft, originally built under the name GeoEye 2, was renamed WorldView 4 after the merger.

"WorldView 4 will help us continue to transform the way we see the world, and advance our mission of keeping our planet and its people safe and secure," said Dr. Walter Scott, founder and chief technology officer of DigitalGlobe.
"Only the DigitalGlobe constellation, with the addition of WorldView 4, offers the highest quality, and most comprehensive global coverage of our changing planet through 2030, so our customers can be confident they will have the information to make critical decisions."
WorldView 4 is designed to see objects as small as 1-foot-wide (31 cm) in panchromatic mode and has a 4-foot resolution (1.24 m) in color. It will image 263,000 square miles (680,000 square km) of the Earth's surface per day, doubling the capacity of WorldView 3 now in service providing the same quality high-res data.
"DigitalGlobe's smart imagery serves hundreds of thousands of end-users charged with the safety and security of nations, and enables the maps and geospatial applications relied on by billions of consumers," said Carl Marchetto, vice president and general manager of Lockheed Martin Commercial Space.
WorldView 3 was launched on Aug. 13, 2014 from Vandenberg aboard another Atlas 5.
The WorldView 4 spacecraft will launch aboard the Atlas 5 originally built to send NASA's InSight lander to Mars earlier this year. The vehicle, designated AV-062, was stacked on the pad awaiting that mission when an instrument problem delayed the launch until 2018, when Earth is again in alignment with the red planet.
Since both InSight and WorldView 4 are using the same rocket configuration — a 401 variant with no solid motors — the passengers could be easily swapped.
After WorldView 4 came out of lengthy storage, Lockheed Martin technicians completed health checks of major systems and tested image collection and downlinking capabilities.
It was trucked by road to Vandenberg on Monday, July 24.

The launch site processing activities will include a final round of testing, the loading of 1,000 pounds of orbital maneuvering propellant and encapsulation within the rocket's 14-foot-diameter nose cone before delivery to the pad in early September for mating to the rocket.
In addition to WorldView 4, the rocket also carries a box of seven cubesats to be deployed into a different orbit from the primary payload. The tiny hitchhikers are being launched from Centaur's Aft Bulkhead Carrier.
It will mark the 15th commercial mission for the Atlas 5 and the rocket's 12th launch from Vandenberg.
The launcher has flown 64 times to date. It has one flight, from Cape Canaveral, lined up before WorldView 4 to launch NASA's OSIRIS-REx asteroid sample return mission on Sept. 8.

Seven weeks to the day after their launch was postponed by a massive wildfire and the aftermath, a commercial Atlas 5 rocket and Earth-imaging satellite are scheduled to fly on Sunday, Nov. 6 from Vandenberg Air Force Base in California.
The day's launch window, which has moved up one hour by the conclusion of Daylight Savings Time, extends from 10:30 to 10:46 a.m. local (1:30-1:46 p.m. EST; 1830-1846 GMT).
The United Launch Alliance booster will head southward from Space Launch Complex 3-East toward a polar orbit. Deployment of the payload occurs 19 minutes after liftoff.
The fire started in a remote canyon south of the launch pad the evening before the planned Sept. 18 launch. The flight was postponed so that firefighters could remain in place to battle the blaze.
More than 12,000 acres across the South Base of Vandenberg were burned by the fire that took nearly a week to contain.
"This fire was an aggressive fire, and as you can see, jumped over roads and spread rather quickly," said Lt. Col. Alex Mignery from the 30th Space Wing's Civil Engineer Squadron and leader in the recovery efforts.
"Luckily, no facilities were gobbled up by the fire, and all the space launch complexes survived as well," he told reporters during a recent tour of the burned areas.
It is considered the largest fire in Vandenberg's history, fueled by the state's drought, and severely impacted the power and communications infrastructure at the base.
The Air Force says its 30th Space Communications Squadron has been validating more than 200 miles of copper and fiber cable crisscrossing the burned areas, which involves hiking into often mountainous terrain and visually checking the cables.
What caused the fire remains under investigation by authorities.
But repairs have been underway to enable the Atlas countdown and launch, and teams have been holding at the L-12 day point in preparation.
The WorldView 4 satellite, which was built by Lockheed Martin and will be operated by the commercial firm DigitalGlobe, has remained atop the Atlas 5 during the long delay. It was protected by the rocket's nose cone and the pad's mobile service gantry during the wildfire.
The craft will circle the planet at 383 miles and snap the highest-resolution images of the Earth's surface available in the marketplace.

ЦитироватьDigitalGlobe: No impact seen fr om WorldView-4 delay or NGA contract with Planet

PARIS — Geospatial imagery and services provider DigitalGlobe on Oct. 25 reported increased revenue and gross profit for the three months ending Sept. 30 with a surprisingly large increase in commercial business.
Westminster, Colorado-based DigitalGlobe, whose main revenue source is a 10-year contract with the U.S. National Geospatial-Imagery Agency (NGA), brushed aside NGA's recent contracts with operators of small-satellite constellations, saying it's a long-expected flirtation.
Asked specifically to address a $20 million NGA contract with San Francisco-based Planet, DigitalGlobe Chief Executive Jeffrey R. Tarr said:
"There's nothing new there. NGA has been talking for a couple of years now about experimenting with some of the emerging small-sat players as they come on line. We see no impact whatsoever on our relationship with the NGA. Very different use case: We're foundational and part of the core [NGA] mission."
The launch of DigitalGlobe's WorldView-4 satellite, whose 30-centimeter ground resolution is dedicated to the company's non-U.S. government customers, has been delayed fr om September and is now scheduled for Nov. 6.
In a conference call with investors, DigitalGlobe Chief Financial Officer Gary W. Ferrera said the launch delay is not expected to have any material impact on the company's 2017 revenue.
DigitalGlobe has 10 Direct Access Partners that can control the spacecraft within their specified geographic territories up to the lim it of their contracts' imagery volume. DigitalGlobe has said several DAP customers were frustrated at their limited access to the in-orbit WorldView-3 satellite's 30-centimeter imagery, much of which has been pre-purchased under the NGA contract.
WorldView-4 will open that same resolution, which is currently without equal on the global commercial market, more widely to the company's commercial customers.
Once WorldView-4 is in service, DigitalGlobe's next capacity-augmentation event will be the scheduled 2019 launch of six or more smaller satellites, each with a ground resolution sharper than one meter but likely not as sharp as WorldView-4.
Ferrera said contractual commitments and letters of intent for WorldView-4 imagery so far could add $55 million to the company's annual revenue.

A Saudi constellation in 2019, and its own bigger satellites in 2021
These smaller satellites, called Scouts, will be operated as a constellation. The satellites' development and launch are being managed by two Saudi Arabian government entities, Taqnia Space and the King Abdulaziz City for Science and Technology (KACST).
DigitalGlobe has not disclosed details on the revenue share for the Scout constellation beyond saying the Saudi-built satellites will be used to give DigitalGlobe a "tip and cue" capability wherein the smaller satellites spot something of potential interest and then inform DigitalGlobe's higher-resolution satellites to take a closer look.
Starting in 2017, DigitalGlobe expects to begin investment in one or more satellites to replace the company's aging WorldView-1 and WorldView-2 satellites. Tarr said the entire spending program — presumably including the satellites' construction, launch and insurance — would be no more than $600 million.
Tarr declined to specify the imaging capability of the next satellites but said DigitalGlobe intends "to sustain our lead in resolution."
The current 30-centimeter resolution is already at the lim it of what the U.S. government will permit for commercial satellite imagery. But Tarr said the the new spacecraft could reduce the time between image acquisition, a key metric for many government and commercial customers.
For the three months ending Sept. 30, DigitalGlobe reported revenue of $181.8 million, up 4.9 percent over the same period a year ago. Adjusted EBITDA, or earnings before interest, taxes, depreciation and amortization, was 53.7 percent of revenue, up from 53 percent the previous year.
The company said its full-year 2016 revenue would be between d$700 million and $710 million, flat from 2015. But EBITDA is expected to be 52.5 percent of revenue against 50.5 percent last year.
U.S. government-derived revenue for the three months ending Sept. 30 was $114.5 million, up 3.2 percent from the previous year. While the company's core 10-year EnhancedView contract with NGA was stable, as expected, the government purchased more value-added services from DigitalGlobe than a year ago.

A commercial surprise and a Russian rebound
The real surprise in the quarterly results was on the commercial side. Diversified commercial revenue was up 8 percent from last year, to $67.3 million. DAP customers accounted for $30.3 million of the commercial total, up 4.8 percent.
Tarr said Microsoft, which sold much of its mapping business to Uber, it retained the portion that feeds its Bing internet search engine, which like all location-based services must be regularly refreshed.
DigitalGlobe said its Russian business, which in the past couple of years has fallen sharply, appears to be rebounding, with revenue increases for each of the first three quarters of 2016. As of Sept. 30, Russian customers generated $5.4 million in revenue, compared to $4.3 million for all of 2015.

The belated launch of a powerful Earth-imaging satellite that will take the highest resolution pictures in the market, postponed by an unprecedented wildfire near the pad, is scheduled to fly on Friday.
A United Launch Alliance Atlas 5 rocket will propel the WorldView 4 spacecraft into a sun-synchronous polar orbit from Vandenberg Air Force Base in California.
Friday's launch window, which has moved up one hour by the conclusion of Daylight Savings Time, extends from 10:30 to 10:45 a.m. local (1:30-1:45 p.m. EST; 1830-1845 GMT).
Air Force meteorologists say there is a 100 percent chance of acceptable weather conditions.   
The liftoff comes nearly eight weeks after the Sept. 18 countdown, already in progress, was halted so firefighters could remain in place to battle a wildfire burning in a remote Vandenberg canyon south of the launch pad.
It took nearly a week to contain the erratic and swift-moving blaze, which burned more than 12,500 acres. What sparked the fire remains under investigation.
Although the launch pad was unharmed, the fire damaged the power and communications infrastructure at Vandenberg that has taken several weeks to repair.
The WorldView 4 satellite, built by Lockheed Martin for operator DigitalGlobe, weathered the fire in the snug confines of the nose cone of the Atlas 5 rocket, which itself was cocooned by the pad's mobile service gantry.
A further slip this week was made to verify the booster's readiness.
It will take 19 minutes, including a single burn by the Centaur upper stage, for the Atlas 5 to accelerate the 5,479-pound payload into an orbit of 379 by 390 miles, tilted 97.96 degrees to the equator, flying from pole to pole to image virtually anywhere on the planet.

Not only postponed two months by the wildfire, WorldView 4's deployment comes more than three years after its original launch target, a delay caused by a corporate merger by former competitors GeoEye and DigitalGlobe.
That marriage brought the two companies together, blending their operations and independent fleets of imaging satellites into one powerhouse firm.
While both companies were developing state-of-the-art satellites for launch before the merger, the new firm opted to launch DigitalGlobe's WorldView 3 satellite first since it also provided multiple short-wave infrared bands that could penetrate haze, fog, dust, smoke and other airborne particulates.
That left GeoEye's bird on the ground to await market demand for its launching to effectively double DigitalGlobe's high-resolution imagery collection capacity. The craft, originally built under the name GeoEye 2, was renamed WorldView 4 after the merger.
WorldView 4 is designed to see objects as small as 1-foot-wide (31 cm) in panchromatic mode and has a 4-foot resolution (1.24 m) in color. It will image 263,000 square miles (680,000 square km) of the Earth's surface per day, doubling the capacity of WorldView 3 now in service providing the same quality high-res data.
"Importantly, WorldView 4 will substantially increase our ability to image the world with the resolution, accuracy and clarity far beyond that of all other commercial providers, enabling us to better serve our international defense and intelligence customers and advance new commercial use cases," said Jeffrey Tarr, DigitalGlobe chief executive officer.

WorldView 3 was launched on Aug. 13, 2014 from Vandenberg aboard another Atlas 5. Its imaging capacity is filled by the U.S. government, DigitalGlobe's biggest customer.
The WorldView 4 spacecraft will launch aboard the Atlas 5 originally built to send NASA's InSight lander to Mars earlier this year. The vehicle, designated AV-062, was stacked on the pad awaiting that mission when an instrument problem delayed the launch until 2018, when Earth is again in alignment with the red planet.
Since both InSight and WorldView 4 are using the same rocket configuration — a 401 variant with no solid motors — the passengers could be easily swapped.
After WorldView 4 came out of lengthy storage, Lockheed Martin technicians completed health checks of major systems and tested image collection and downlinking capabilities. It was trucked by road from Sunnyvale to Vandenberg on July 24.
The launch site processing activities included a final round of testing and the loading of 1,000 pounds of orbital maneuvering propellant. On Sept. 2, encapsulation within the rocket's 14-foot-diameter nose cone was performed and delivery to the pad occurred on Sept. 7 for mating to the rocket.
In addition to WorldView 4, the rocket also carries seven cubesats to be deployed into a different orbit from the primary payload as part of a National Reconnaissance Office-sponsored rideshare mission called ENTERPRISE. The tiny hitchhikers are being launched from Centaur's Aft Bulkhead Carrier for technology research.
Friday's countdown will begin ticking at 2:30 a.m. local time, followed by retraction of the gantry three hours later. Fueling of the vehicle with 66,000 gallons of liquid oxygen and liquid hydrogen should start around 8:15 a.m. local.
It will mark the 15th commercial mission for the Atlas 5 and the rocket's 12th launch from Vandenberg. The launcher has flown 65 times since 2002.

The 8-million-pound mobile service tower has been retracted from around the Atlas 5 rocket, revealing the 19-story-tall vehicle for liftoff at 10:30 a.m. local time today.
The ground crews are getting the gantry's doors closed, plus finishing the final buttoning up of pad equipment before all workers clear the pad for the remainder of the countdown.

January 07, 2019

WESTMINSTER, CO, Jan. 7, 2019 /PRNewswire/ - Maxar Technologies Inc. (NYSE:MAXR) (TSX:MAXR) ("Maxar" or the "Company"), a global technology innovator powering the new space economy, today reported that its WorldView-4 satellite experienced a failure in its control moment gyros ("CMGs"), preventing the satellite from collecting imagery due to the loss of an axis of stability.

Efforts are ongoing in conjunction with its suppliers in an attempt to restore satellite functionality, but thus far these efforts have been unsuccessful. At this time, Maxar believes that WorldView-4 will likely not be recoverable and will no longer produce usable imagery. Maxar operations has put the WorldView-4 satellite in a safe configuration and will continue to monitor the satellite's location and health. The satellite was built by Lockheed Martin and the CMGs were provided by Honeywell.

Спойлер

WorldView-4 was acquired by GeoEye prior to its merger with DigitalGlobe in 2013. It was launched in November 2016 and generated revenues of approximately $85 million in fiscal year 2018. The satellite had a net book value of approximately $155 million, including related assets, as of December 31, 2018. If the satellite is not recoverable, then the net book value will be written off in Q4-2018. Contingency planning and mitigation efforts are underway to assess the use of the Company's other satellites and outside resources to replace imagery collected by WorldView-4 and meet as much of the existing customer commitments and obligations as possible. The Company currently believes it will be able to offset $10 to 15 million of the annual revenue from WorldView-4 and will work to minimize the potential impact on Maxar's financial results in future years.

The WorldView-4 satellite is insured for $183 million, and Maxar intends to seek full recovery for the loss of WorldView-4 under its insurance policies. The Company will provide further updates on this matter as new information becomes available.

Акции Maxar Technoogies Inc. (MAXR) продолжили во вторник падение до нового рекордного минимума, в связи со сбоем в работе спутника  WorldView-4. 
Акции Maxar демонстрируют самое сильное снижение на NYSE, после того как в понедельник вышло сообщение об отказе гироскопов спутника, препятствующем его работе. Спутник, запущенный в ноябре 2016 года, со страховкой на $183 млн, принес $85 млн выручки в 2018 финансовом году. National Bank of Canada понизил рейтинг акций Maxar до уровня "по сектору" и целевую цену на 78% до $10. CIBC понизил цель на 20% до эквивалента $15, оставив нейтральный рейтинг.

Почему "был"? Разве Viasat-2 дал дуба? У него просто проблемы с антеннами, что сказалось на производительности его, ну как я читаю сейчас... но он не окончательно потерян же.
