Early demonstrations of low-budget medical data relay and doppler location of ground transmitters for search-and-rescue operations were done using this satellite.

The satellite started sending telemetry again on 21 Jun 2002; it works when the solar panels provide enough power (in sun light). The battery seems to have unshorted.
