- Abstract
National Space Organization (NSPO), Taiwan, successfully launched a two-meter resolution remote sensing satellite, Formosat-2, in year 2004. Formosat-2 is now the unique satellite of the world having the capability of mission execution with daily revisit and daily repeat performance. The satellite can continuously image the same target with the same viewing angle condition for consecutive days, which is excellent for monitoring phenomenon change of target. However, to reach the orbit altitude, 891 km like Formosat-2, which is relatively too high to be inserted by a small launch vehicle, is becoming a cost issue. Therefore, NSPO is developing the next generation remote sensing satellite for the continuation of Formosat-2 applications. The mission performance and cost effectiveness are both considered for the system definition through the optimization processes of system design trade-off studies. The mission orbit is re-selected for considering the capability of small launch vehicles. The orbit candidates are selected from 500 km to 800 km. This paper presents the mission orbit selection, the trade-off studies, and the rationales for the mission orbit selection results. The simulation of the mission performance of the candidate orbits is demonstrated. The requirements for orbit insertion and orbit maintenance have also been analyzed.
