iPStar 1 (Thaicom 4, MEASAT 5, Synertone 1)

iPStar 1 [SSL]

iPStar-1 (Thaicom 4) is a high-powered geostationary satellite to be used for broadband communications applications by Shin Satellite Plc. of Thailand. iPSTAR-1 will provide direct-to-desktop, last-mile services, including new multimedia and data services to customers in Asia, India, and Australia.

Featuring 87 Ku-band transponders and 10 Ka-band transponders and weighting 6505 kg, iPStar 1 will be the heaviest commercial geostationary communications satellite. It is based on Space Sevice Loral's SSL-1300S bus.

Thaicom announced in late May 2011 a major new contract with Malaysia’s MEASAT satellite operator for capacity aboard the Thaicom 4/IPStar Ku-band consumer broadband satellite. Financial details were not disclosed for the 10-year contract, under which MEASAT will purchase access to seven IPStar spot beams delivering a total of 3.3 gigabits per second of throughput, which Thaicom said is seven percent of the satellite’s total capacity. The bandwidth will be marketed in Malaysia as MEASAT 5. China's Synertone Communications Corporation in 2013 acquired iPStar 1 coverage for China including Hongkong and Macau and renamed this Capacity as Synertone 1
