- Abstract
Taiwan’s second remote sensing satellite is currently being developed by its National Space Organization (NSPO). We can call it temporarily FORMOSAT-X. Launched on 20 May 2004, Taiwan’s first remote sensing satellite named FORMOSAT-2 has a mission life of 5 years. It is therefore very necessary for Taiwan to develop the second one to be the follow-on of FORMOSAT-2. The strategy of developing Taiwan’s second remote sensing satellite is different from its first one. In FORMOSAT-2, NSPO cooperates with EADS Astrium of France to develop the bus and the remote sensing instrument, and cooperates with the University of California at Berkeley of USA to develop the scientific payload. In the FORMOSAT-X, both the bus and the payloads shall be developed domestically in Taiwan. NSPO shall be the prime contractor of the bus and the Instrument Technology Research Center (ITRC) of Taiwan shall be the prime contractor of the remote sensing instrument. The scientific payload shall be developed in the cooperation of domestic universities in Taiwan and other universities outside Taiwan. Major characteristics of the FORMOSAT-X are as follows: 1. Total mass: less than 500 kg 2. Propellant mass: about 80 kg, cold gas 3. Orbit altitude: 639 km, sun-synchronous 4. Ground sampling distance: 2.5 m for panchromatic and 10 m for multi-spectral 5. Number of bands: panchromatic and 4 multi-spectral 6. Swath: no less than 40 km 7. Power generation: 300 W 8. Duty cycle: 89. Shape: basically rectangular 10. Launch time: fourth quarter of 2010 NSPO has completed the system design review of FORMOSAT-X. The preliminary design review shall be held in June 2007.
