Program: Formosat 3


Also called COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climat)

United States and Taiwan scientific program worth $100 million. Originally known as Rocsat 3.

Six satellites were ordered in Mar 2001. OSC should provide them for $56 million. The program intially called for 8 satellites.

It will take 13 months for all satellites to settle in their designed orbital planes with a longitudinal separation of 24 degree, altitude of about 700-800 km, and inclination of 72 degrees.

In Oct 2007, it is announced that only 3 out of 6 satellites are still operational.

In May 2008, the satellites recorded a sharp drop in ionospheric density above China's Sichuan Province before the Earthquake. That could verify previous records that seismic activities affect ionospheric density.

In 2013, SSTL received a contract to provide upto 12 satellites for the Formosat 7 / cosmic 2 constellation. Launch planned in 2016. Each satellite is less than 200 kg.
