ROCSAT

Part of T200

ROCSAT

Taiwanese earth sea satellite. Taiwan's ROCSAT (Republic of China Satellites) were built for Taiwan's National Space Program Office. Earth Observing satellite built by TRW for NSPO, Taiwan. Launched 1999. Used the T200A bus.

AKA: Theos. Status: Operational 1999. First Launch: 1999-01-27. Last Launch: 2008-10-01. Number: 3 . Gross mass: 400 kg (880 lb).

The test satellite series progressed from all-American to all-indigenous satellite components.

Taiwan's first satellite, ROCSAT (Republic of China Satellite) was built by TRW for Taiwan's National Space Program Office. ROCSAT carried a Ka-band experimental communications payload, an ocean color imager experiment to study plankton distribution for fisheries management, and an instrument to measure thermal plasma in the equatorial ionosphere. It was equipped with a small hydrazine orbital adjustment engine.

ROCSAT-2, scheduled for 2003, was to observe and monitor the terrestrial and marine environment and natural resources throughout Taiwan, its remote islands and surrounding ocean. It would also carry a sprite imager to study electrodynamic coupling between thunderclouds and the upper atmosphere. Taiwan contracted for launch of ROCSAT-2 on an American Taurus booster.

On 4 May 2001 Taiwan and the United States on Thursday signed an agreement to produce and launch by the end of 2005 six ROCSAT-3 micro satellites for weather forecasting. Taiwan companies were to be awarded contracts for the major components. ROCSAT-3 was part of Taiwan's 15-year space program launched in October 1991 at an estimated cost of $ 413 million.
