Amateur radio satellite
Australis-OSCAR 5
(a.k.a.
AO-5
) is an
amateur radio satellite
that was launched into
Low Earth Orbit
on 23 January 1970 by a
Thor Delta
launcher from
Vandenberg Air Force Base
,
Lompoc, California
. AO-5 was launched piggyback with
TIROS-M
(ITOS-1)
weather satellite
).

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.
Firsts

- First amateur satellite to be remotely controlled.
- First amateur satellite launch coordinated by new
AMSAT
organization.
- Switch to Arabic numbering for this and future OSCAR satellites, from earlier Roman numeral usage (I, II, III, IV) by Project Oscar.
