Detailed Description
UoSAT-OSCAR 15 was launched January 22, 1990 by a Ariane 4 launcher from Kourou, French Guiana. Launched on the first Ariane ASAP flight V35 with SPOT-2 and five other microsatellites: UO-14, AO-16, DO-17, WO-18, and LO-19. Weight 47 kg. Orbit 790 x 805 km. Inclination 98.7 degree orbit. Box shaped 350 x 350 x 650 mm. Four solar panels and 6 m gravity gradient boom.
Contained scientific payloads to complement UO-14. On-board electronics failed shortly after UO-15 reached Earth orbit. An effort was made by Stanford Research Institute (SRI) to detect the receiver local oscillator (LO) signals using a 35 meter dish antenna. After considerable work Stanford did detect the receiver signals on several occasions despite reception occurring for only a matter of seconds. Significant post processing of the signals (taking several hours) was required to confirm reception.
