Paper Abstract

In this paper, a broadcast channel model is set up to analyze and validate the real-time performance of the spread spectrum ALOHA used in satellite formation flying. A three-satellite formation flying system model is the concretion of the model. In the model, a frame definition referenced CCSDS recommended standard is imported. According the three-satellite model, this paper deducts the delay probability, the probability of collision and the mean time of communication to estimate the performance of spread spectrum ALOHA. By simulation, it validates that spread spectrum ALOHA has a good real-time performance in the model of satellite formation flying, which could satisfy milliseconds order requirement in distance of several hundred kilometers.
