I wrote APRtrak and donated it to the AMSAT software library to remove any conflict of interest I might have in suggesting that APRtrak can be an excellent tool for amateur experimentation with the satellites. AMSAT issues the validation numbers and receives all contributions for its use.

APRtrak is mostly APRS but it had special coding for the SPRE experiment launched in January 96. It also has the additional antenne "eye" view. Both APRS and APRtrak have the SPACE mode, but the APRtrak will probably be more up to date...

APRtrak will NOT plot terrestrial packets that have more than ONE digipeater in the path... For more information, read the SPACE.HTM file.
