Abstract:

In this paper, a random access inter-satellite ranging (RAISR) system is designed. The ranging accuracy is optimized by an algorithm to greatly improve the ranging accuracy. This paper verifies the feasibility of the RAISR system through a series of theoretical analysis, numerical simulation, hardware system design and testing. The research work brings the solution to the design and accuracy optimization problem of the RAISR system, which eliminates the main error caused by the satellite dynamic characteristics and frequency source drift of the RAISR system. The accuracy of the measurement system has been significantly improved.

Key words: satellite ranging, random access, distributed network
