Detailed Description
Australis-OSCAR 5 was launched January 23, 1970 by a Thor Delta launcher from Vandenberg Air Force Base, Lompoc, California. AO-5 was launched piggyback with ITOS-1 (TIROS-M weather satellite). Orbit 1476 x 1431 km. Inclination 101.8 degrees. Period 115 minutes. Weight 17.7 kg (9 kg of which was battery mass). Box shaped 304 x 431 x 152 mm. 2 meter monopole and 10 meter dipole antennas.
Firsts: The first amateur satellite to be remotely controlled.
Built by students at The University of Melbourne, Melbourne, Victoria, Australia. Battery powered, Australis-OSCAR 5 transmitted telemetry on both 2 meter (144.050 MHz at 50 mW) and 10 meter (29.450 MHz at 250 mW) bands that operated for 23 and 46 days respectively. Passive magnetic attitude stabilization was performed by carrying two bar magnets to align with the Earth's magnetic field in order to provide a favorable antenna footprint. The University of Melbourne compiled tracking reports from hundreds of stations in 27 countries.
