A NEW METHOD OF INITIAL ORBIT CALCULATION FOR SATELLITE BASED ON ATTITUDE SENSORS DATA USING GENETIC ALGORITHM

摘要

In this paper, a new method of initial orbit determination for satellite by the use of attitude data is proposed, while introducing Genetic Algorithm (GA) into the initial orbit calculation. According to Keplerian Law, a new kind of uniform formula of initial orbit calculation based on pure angle measurements is established. A fast growing operator is adopted to heighten the efficiency of GA's computation, and an Algorism Float-Coded Genetic Algorithm (AFCGA) is designed, which has high convergence speed, high optimization accuracy and simple realization. In the end, simulation results of several typical orbits show the validity of AFCGA.
