Abstract :
In-orbit channel measurements were obtained from a low Earth orbit (LEO) satellite, at the Surrey Satellite Technology Limited groundstation at the University of Surrey. Analysis on the error sequences show the LEO satellite channel to be reasonably described by a 4-state probabilistic Markov model. Based on the most advanced LEO store-and-forward communication protocol, the design and selection of hybrid-ARQ schemes with Reed-Solomon codes is highlighted. From the simulation results, the research looks towards implementation and in-orbit demonstration of these hybrid-ARQ schemes
