Positioning Research, Based On The Binary System Of Pseudo-satellite Passive Region

The theory and method of the region passive pseudolites positioning based on geostationary satellite positioning system are systematically discussed.The geostationary satellite positioning system of China is region satellite navigation system. The system is easy to be jammed as a result of active positioning mode. Therefore, it is very significant to find the way of realizing passive positioning.A method of the region passive pseudolites positioning based on geostationary satellite positioning system is presented. Firstly, the positioning theory and method are discussed and the positioning accuracy is analyzed. Following that, several factors that affect the position of pseudolites are discussed. Then the error analysis is given in several cases. In the end, some concrete problems such as far/near problem and synchrolite problem are discussed.Theoretical analysis and some numerical simulation are also given to show its validity and feasibility.
