Singapore-Taiwan-1 Matra Marconi Space Eurostar 2000 class satellite to provide communications for Singapore Telecom and Chunghwa Telecom of Taiwan. Geostationary at 88.0 degrees E. Positioned in geosynchronous orbit at 88 deg E in 1998-1999 As of 5 September 2001 located at 88.04 deg E drifting at 0.009 deg W per day. As of 2007 Mar 10 located at 88.05E drifting at 0.007W degrees per day.

Taiwan's first satellite, with experimental communications, ocean imagery, and ionospheric studies instruments. The Primex OAM placed itself and the payload into an elliptical transfer orbit. A second OAM burn circularized the orbit, and ROCSAT separated into a 588 x 601 km x 35.0 deg orbit.

FORMOSAT-3 consisted of six small 62 kg Orbcomm-type satellites with GPS receivers which were to measure atmospheric conditions by studying the effect of the atmosphere on GPS satellite signals passing through it. The satellites, also known as COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climate), each raised their orbits over several months, all but one reaching operational orbits of around 770 x 840 km by September 2007.
