Abstract

In the mission of satellites, instantaneous positioning and estimation of the future position are necessary. In the communication satellite, this matter is so important. Thus in the Tadbir satellite, for the first time in the country, we consider an orbit determination subsystem that equipped with a spaceborne GPS receiver and contains appropriate algorithms in order to achieve satellite position data during the lunch period and in the orbit. In this paper a brief review of the software and hardware parts of this subsystem is presented. In additional the process of testing to achieve good performance, including functional tests of ODS processor board and functional test of GPS receiver with GPS simulator, environmental condition tests, mechanical tests, thermal vacuum cycle tests, electromagnetic compatibility test and finally integrated satellite tests are stated. This paper, in addition to a description of the Tadbir satellite orbit determination subsystem, an implementation testing of a satellite subsystem is demonstrated, which can be useful to other space field researchers.
