A high-power communications satellite deployed from China

An internet-provider broadband communications satellite for airline passengers, mobile users, fishing vessels, and cruise ships was deployed this Thursday via the Chinese Long March 3B rocket.

The 5550-kilogram Apstar-6D communications satellite took off from the Xichang space launch site at 1211 GMT. This Xichang launch site is in Sichuan province in Southwestern China. The Long March 3B rocket hoisted the payload to the east-southeast of Xichang. The 56-meter tall spacecraft was able to detach its four boosters and the core capsule in the initial two-and-a-half flight minutes. The vehicle then fired up the rocket’s second stage before flipping to stash the rocket’s upper stage and let out the Apstar-6D satellite in its orbit.

The Apstar-6D satellite detached itself from the Apstar-6D rocket’s third stage within thirty minutes. This statement implies that the rocket covered over 26000 kilometers in such a short time. The craft’s propulsion system will realign it to fit the equatorial geostationary altitude in with time attaining a velocity close to Earth’s spinning speed.

The spacecraft is a product of APT Mobile Satcom Ltd, whose headquarters are at Shenzhen in China. This firm is a formation by the APT Satellite of Hong Kong and other parastatals in mainland China.

APT Satellite claims that the Apstar-6D spacecraft will facilitate the connection of mobile satellite communication and satellite broadband demands in the Asia-Pacific region. An operator submits that the satellite will finalize the second stage of launching the power-generating solar arrays. Additionally, they will be designing the unfurl antennas for tryouts before committing to commercial services. 

The Apstar-6D spacecraft is a construction of the China Academy of Space Technology, which made alterations on China’s DFH-4 satellite platform called DFH-4E. The satellite will utilize the liquid-fueled engine to propel it in its orbit and electric plasma thrusters to maintain its geostationary orbit in the 15-year mission.

APT Satellite acquiesced the satellite and the launch go-ahead through the China Great Wall Industry Corp (CGWIC). This parastatal is responsible for the selling of Chinese spacecraft and launch services on the global market. 

The Apstar-6D contains Ku-band and Ka-band communications payloads whereby 90 Ku-band spectrum meets the needs of customers while the eight Ka-band forms the gateway beams. The satellite will be stationarily covering the firmament of the eastern Indian Ocean and the Western Pacific Ocean.

Finally, the craft will be serving Chinese airlines, marine companies, and other natural disaster curtailing firms and agencies. This satellite is capable of sending 1 gigabit per second of data in a single stream beam and also give out 14.4 kilowatts of power.
