The Pseudolites Application Study In The Beidou System

False artificial satellite technology application in the system fixing position in the Plough navigation the main body of a book has been discussed systematically, the improvement to the Plough system allocation accuracy and their improvement to the Plough system allocation accuracy.The Plough system is the area satellite navigation fixer system that our country designs by self. Since the person fixes position, processis that the active fixing position on self's own initiative , disturbs easy to. Therefore, go ahead in now available system ability basis , allocate the false artificial satellite base stand rationally, passive realizing a regional fixes position having importance.The system fixing position one kind owing to passive area of false the Plough artificial satellite that the main body of a book has been submitted, is to set up false appropriate artificial satellite system , to increase observation amounts , the passivity making use of false distance to measure method allocation , realizing systematic passive thereby fixes position. Allocation principle and the method fixing position the main body of a book has been discussed first systematically, system strengthens front allocation accuracy by simulating having analysed the Plough, several difficult point in subsequently, having suggested that the false artificial satellite improves a scheme , having analysed the false artificial satellite technology. And then the Plough system improving the day afer tomorrow has carried out analysis on false artificial satellite technology simulating, impact of the distribution having discussed the false artificial satellite base stand subsequently over allocation accuracy, arrange to have provided the certain basis for base stand.The theoretical analysis and the simulation emulation indicate system is feasible have an effect.
