Communications infrastructure for the MOST microsatellite project.

摘要

This thesis reports results from several areas of development, but they have a common theme: all are selected pieces of a complete satellite communication system, from the spacecraft computer and telecommand systems through the radio link to ground station data analysis and dissemination. Each component has several tasks in common: researching alternatives, evaluating a promising selection, implementing that selection (or a subset thereof), and analyzing the results.; The key components of this work were: (1) Creating a prototype suite of spacecraft software to run under SCOS. (2) Creating a prototype suite of ground station software and using it to communicate with the prototype satellite. (3) Establishing an amateur satellite ground station at UTIAS and using it to communicate with present amateur satellites.
