UNAMSAT A, B (Mexico-OSCAR 30, MO 30)

UNAMSAT B (OSCAR 30, UO 30)

UNAMSAT (University of Mexico (UNAM) Satellite) is a 17 kg spacecraft built in Mexico at UNAM, a Mexican University.

The satellite bus is the AMSAT-NA Microsat 25 cm cube. It operates in the amateur service and carries 0.2-0.3 W UHF downlinks at 437.206 and 437.138 MHz, and uplinks at 145.815, 145.835, 145.855 and 145.875 MHz with 1200 bps AFSK modulation using the PACSAT data protocol as used by PACSAT (OSCAR 16) and LUSAT (OSCAR 19).

The primary payload is a 40.997 MHz pulse radar associated with a wide band receiver to study micro-meteorids and the ionised trails left by these as they enter the atmosphere. It also carries a communications data relay for environmental sensors in remote locations.

UNAMSAT A failed to reach orbit due to a launcher failure during the maiden flight of the Start booster in early 1995.

UNAMSAT B microsatellite was launched on the 5th September as a secondary payload on a Kosmos-3M rocket with Kosmos 2334 (Parus #86) from Plesetsk, into a 1010 × 988 km circular orbit inclined at 82.9, with the Parus navigation satellite being the primary payload. In Aug 97 it is reported to have started experiencing trouble with the power system for the downlink.
