The SunSat team released the following statement, dated February 1, 2001:

We regret to announce that the last communication with SunSat from our ground station at the Electronic Systems Laboratory at Stellenbosch University took place recently. We are certain, after having performed several tests since the last contact, that an irreversible, physical failure has occurred on the satellite. It is therefore unlikely that we will have any further contact with SunSat, apart from the occasional visual sighting by telescope!

When it was operational the SunSat package included 1200 and 9600 baud digital store-and-forward capability and a voice 'parrot' repeater system in addition to Mode B/J operation with two VHF and two UHF transmit-receive systems.
