I am looking for a training course on satcoms.

The ARTES online Satcom Training System is free of charge and offers three levels of knowledge, from basic information for non-technical personnel to advanced for expert graduate engineers who need to expand their knowledge outside of their fields. Each level contains tutorials on SATCOM Technologies, System and Services, Communication Link, Space Segment, Networking and Earth Segment. These categories are further divided into more detailed specialist areas and include some exercises at the end.
