Abstract :
This paper introduces one of the experimental payloads on the PoSAT-1 microsatellite, the Digital Signal Processing Experiment (DSPE), the in-orbit channel measurement and equalisation based on this experimental communication payload. In order to optimise and understand the communication characteristics of low Earth orbit satellite communications, channel measurement and equalisation have been carried out by computer simulation, bench test and in-orbit test. The experimental results are presented
