22 January 2005 marks the 15th anniversary of the launch of five OSCAR
microsats, UOSAT-4 (UO-15), PACSAT (AO-16), DOVE (DO-17), WEBERSAT
(WO-18) and LUSAT (LO-19).
UoSAT-OSCAR 15 (UoSAT-4, UoSAT-E) by a Ariane 4 launcher from Kourou,
French Guiana. The satellite was launched on the first Ariane ASAP
flight V35 with SPOT-2 and four other microsatellites: AO-16, DO-17,
WO-18, and LO-19.
Based on the success of UoSAT-OSCAR-11's Digital Communications
Experiment, AMSAT-OSCAR-16 was designed to be a dedicated
store-and-forward file server in space. A total of 10 megabytes of
static RAM was available for message storage and a RAM disk.
DOVE-OSCAR 17 was sponsored by AMSAT-Brazil and lead by Dr. Junior
Torres DeCastro, PY2BJO. The primary mission of DOVE was to provide an
easily receivable signal for educational institutions. Thus requiring
simple equipment like a 2 meter handheld or scanner to receive DOVE's
signal. Telemetry was in the familiar terrestrial 1200 baud AFSK AX.25
packet format requiring a common TNC to decode.
WEBERSAT-OSCAR 18 carried a Mode JD digital transponder and had a 1200
baud AX.25 packet system. Additionally WO-18 carried two 70cm beacons.
LUSAT-OSCAR 19 was coordinated by AMSAT Argentina, as a packet radio
store-and-forward spacecraft much the same as AMSAT-OSCAR-16. The only
difference between the two satellites was that AO-16 supports an S-Band
beacon in addition to the mailbox, while LO-19 had an additional 70-cm
CW beacon.
