Re: OSCAR 24 (ARSENE)



HI
Without other news, AO-24 (ARSENE) it's considered a lost satellite.

ARSENE-OSCAR-24 (AO-24) was launched May 13, 1993 into an equatorial
elliptical orbit. It had Mode B (145.975 MHz downlink (1200 bps FM AFSK))
and Mode S (2446.54 MHz downlink) transponders. ARSENE was a French packet
relay satellite built by French Radio Amateur Club de l'Espace. The packet
system was never implemented because the 2M transponder failed soon after
launch. ARSENE was then used to relay SSB and CW signals on 2.4 GHz for
several months until this transponder failed as well.
