Simulation and Analysis Study on the Position Error of Double-Star Position System

This paper introduces the position principle of the double-star position system, gives the measurement equations of the position system, then simulates and analyses the position errors. On the basis of pointing out the positioning mechanism shortcoming of the double-star position system, the similar simulation and analysis are made on the position errors of two kinds of improvement systems for the double-star position system, then the comparison is made for the three systems. At last the useful conclusion is given
