Paper Abstract

An algorithm for satellite tracking and orbit prediction is presented in detail. Firstly, the satellite's position and velocity are calculated by the Simplified General Perturbations Version 4 and Simplified Deep-space Perturbation Version 4 (SGP4/SDP4) orbit propagation algorithms. And we put forward "Two-Point-Pair" which means two points that the CCD of satellite's IFOV rays intersecting with the earth. We make use of the "Two-Point-Pair" to calculate the accuracy bounding box of satellite at the instantaneous time through the satellite's position and velocity above. Besides, we build a system called GeoGlobe to simulate the algorithm. The system can be used to simulate all kinds of satellites that the Two-Line Element (TLE) Sets files can provide.
