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 communication satellite. It is based on Space Sevice Loral's LS-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.
