Detailed discussions are made of principles and methods associated with orbital determinations for low orbit spacecraft making use of GPS systems. Analysis is done of problems which should be considered with regard to low orbit spacecraft during selection of satellites. In conjunction with this, satellite selection tests are carried out on the basis of navigation satellite as well as user models. Discussions are made of making use of least square methods to make calculations to determine orbits. Detailed analysis is done of Kalman filter algorithms. With a view to low orbit spacecraft, a nine state Kalman wave filter model is put forward. In conjunction with this, simulation analog calculations are carried out on this foundation. Besides this, on the basis of special user requirements with regard to electric power source energies and reliability, one type of relatively practical orbit determination method is put forward. Simulation results clearly show that the method put forward satisfies user requirements in terms of accuracy and is appropriate for actual engineering applications.
