Telstar 19V confirmed in subsynchronous geotransfer orbit of 243 x 17863 km x 27.0 deg; Falcon 9 stage 2 in similar orbit.

The low apogee of the (presumably as-planned) Telstar 19V transfer orbit would imply about 1050 kg of the 7075 kg satellite launch mass will be used to raise apogee to standard GTO

19 ч. назад

Another 3500 kg or so of propellant needed to finally reach GEO, leaving the satellite with a mass of about 2500 kg in GEO if my sums are correct

и #111

The spacecraft will use a hydrazine-fueled engine to finish the climb into a circular geostationary perch over the equator.

и там же

Telstar 19 VANTAGE should arrive in geostationary orbit within a couple of weeks, then enter service by the end of August at 63 degrees west longitude after completing tests and commissioning, along with deployments of solar panels and antennas.

Through these innovative capacity and coverage options, Telstar 19 VANTAGE will deliver important advantages to Telesat customers who serve growing consumer, enterprise and mobility markets.

As previously announced, Hughes Network Systems LLC (Hughes) has signed a 15-year agreement for Telstar 19 VANTAGE Ka-band capacity that Hughes will utilize to expand its broadband satellite services for consumers and businesses in five South American countries. Hughes will refer to this capacity as "Hughes 63 West."

Telesat also has long-term contracts for the entire Ka-band capacity of Telstar 19 VANTAGE over Northern Canada, including providing Bell Canada subsidiary Northwestel with the HTS spot beam capacity required to enhance broadband connectivity for all 25 communities in Nunavut, Canada's northernmost territory.

"The pre-launch agreements Telesat has secured with Hughes and Bell Canada, combined with strong interest from other leading satellite service providers across the Americas and Atlantic, confirm that Telstar 19 VANTAGE delivers superior performance and value for today's bandwidth intensive applications," said Dan Goldberg, Telesat's President and CEO. "The design and capabilities of Telstar 19 VANTAGE enable our customers to provide more advanced satellite broadband to their end users. We would like to thank SpaceX for the successful launch of Telstar 19 VANTAGE and for their dedication and professionalism throughout this mission. In a few weeks, Telesat will again be working with SpaceX for the launch of our next satellite, Telstar 18 VANTAGE over Asia."

Telesat's Newest Satellite

SpaceX successfully launched Telstar 19 VANTAGE to Geostationary Transfer Orbit (GTO) aboard a new Falcon 9 rocket. Liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station was at 1:50am ET on Sunday, July 22nd. About 33 minutes after liftoff, Telesat's newest satellite with a launch mass of 7,080 kg was deployed from the Falcon 9. Ku-band coverages of Telstar 19 VANTAGE include: Brazil regional beam, North Atlantic regional beam and HTS spot beams over Brazil and the Andean region. Ka-band HTS spot beams of Telstar 19 VANTAGE cover: South America, the Caribbean, the North Atlantic and Northern Canada.

Telstar 19 VANTAGE is expected to enter commercial service this summer after it has successfully completed orbit raising and comprehensive in-orbit testing. The satellite has a 15 year design life.

SpaceX delivers largest commercial satellite in kick off of Falcon 9 marathon

By Eric Ralph
Posted on July 22, 2018

SpaceX has successfully completed its 13th launch of 2018, kicking off a marathon of three new Falcon 9 Block 5 booster debuts with the launch of the Telstar 19V communications satellite, potentially breaking the record for the largest commercial satellite ever launched at 7000 kg (15,500 lb).

Despite the heft of its payload and partially thanks to a slightly lower parking orbit for the satellite, Falcon 9 booster B1047 – the second Block 5 booster to roll off the assembly line – managed to successfully land aboard the autonomous spaceport drone ship (ASDS) Of Course I Still Love You (OCISLY), stationed approximately 650 km (400 mi) off the Florida coast at launch time.

While the booster was unable to maintain a live video feed through its high-speed reentry and Atlantic landing, SpaceX's cameras on OCISLY managed to reconnect a few seconds after touchdown to show the 50-meter (160-foot) tall rocket safely resting on the drone ship. As the webcast host noted, Falcon 9 Block 5 features a number of prominent upgrades designed to enable levels of reusability and reliability essentially unprecedented in the world of orbital rocketry.

Есть. И на ЭРД Вы хотите меньше чем за месяц выйти на ГСО, чтобы успеть провести тестирование на орбите и передать сабж в эксплуатацию к концу августа? SES-14 на ЭРД с января только к середине июля сумел доползти до ГСО, тогда как собрат по запуску Al Yah 3 на апогейнике дошел до ГСО к 3-му мая, за май прошел IoT и с июня уже начал работу по назначению (хотя вывод на орбиту был аномальным по наклонению). SES-12 на ЭРД всё ползёт вверх, за полтора месяца после запуска дополз аж до 5500 км перигея...
Когда писал "никаких", считал понятным из приведенных цитат невозможность использования ЭРД для быстрого выхода на ГСО, не более того.
