Abstract: This article describes a visualization software of GEO satellite orbit determination, which is developed in the Windows systemby adopting the Microsoft Visual Studio 2005 software platform and using theVisual Basic.NET programming technique. This software can pre-process observation data, compute GEO satellite orbit with high accuracy, analyze and plotthe calculated results of satellite orbit, etc. Furthermore, this software has virtues such as friendly interface, high operability, convenience and time-saving, so as to improve the efficiency of GEO satellite orbit determination.

Key words: GEO satellite; orbit determination; visualization software
