UoSAT-3 exceeded its expected operational life by 3 years and ceased active service in 1999. However, amateur radio enthusiasts managed to track the satellite for a certain amount of time afterwards via the satellite's FM voice transponder.
The satellite, which is now non-operational, forms a part of the growing amounts of space debris orbiting around the Earth. The payload will decay in the Earth's atmosphere some time in the future.
Payloads are separated by bullets ( · ), launches by pipes ( | ). Manned flights are indicated in bold text. Uncatalogued launch failures are listed in italics. Payloads deployed from other spacecraft are denoted in (brackets).
