Enhancements over AsiaSat 4

Additional capacity, enhanced power and coverage for video applications such as DTH, video contribution / distribution, also data applications such as VSAT private networks (corporate, mobile backhaul etc.) and broadband services across the Asia-Pacific region.

C-band: Greater Power, More Bandwidth, Higher Efficiency and Wider Coverage with Asia’s highest powered 110 watts C-band TWTA.

Ku-band: 3 new dedicated high power Ku-band beams covering Indonesia (downlink EIRP up to 55dBW), Myanmar (up to 55dBW), Mongolia (up to 52dBW), in addition to enhanced East Asia and Australasia beams; Cross-strap switching capability to allow uplink and downlink across different Ku-band beams.

Unique Benefits & New Cutting Edge Features

Introducing 3 powerful Ku-Band Beam (Myanmar, Indonesia and Mongolia) and new cross-strap beam switching capability for flexible coverage -  e.g. uplink from East Asia beam and downlink via Myanmar beam, or vice versa

Doubling spectral density (bit/Hz) - to support higher mod/cod on areas with 3dB enhancement in the downlink EIRP power

Improved uplink G/T contour (dB/K) - allowing an optimised usage of customer HPA for remotes sites

Special filter design on spacecraft -  to achieve higher bandwidth for C-band transponders. With combined higher power and wider bandwidth, AsiaSat 9 delivers significantly higher throughput

Employment of conduction-cooled LTWTA - improves panel layout to provide more consistent EIRP across channels, meaning a higher degree of performance stability for multi-transponder customers

Star Tracker - Robust and reliable way to ensure a higher pointing accuracy, about 20% better than traditional earth sensor only spacecraft

Stationary Plasma Thrusters (SPTs) - Equipped with Hall Effect Thrusters that use electrical energy to change the velocity of the spacecraft which more efficiency than chemical thrusters. As a result, higher stability and reliability can be achieved for stationkeeping and better performance at edge of coverage
