The Argentine ÑuSAT-1[1] carrying the LUSEX[2] (LU Satellite Experiment)
Amateur Radio U/V linear transponder and 436 MHz beacon launched May 30 at 0317
UTC from China. With ÑuSAT-1 on the launch was sister satellite ÑuSAT-2, which
carries a 437 MHz beacon. Gunter's Space Page reports that the Argentinian
ÑuSat Earth-observation satellites form the Aleph-1 constellation developed and
operated by Satellogic[3] S.A. The satellites are equipped with an imaging
system operating in visible light and infrared. The Aleph-1 constellation will
consist of up to 25 satellites. Signals have been reported from both telemetry
beacons, and Satellogic reports, "All Systems: Nominal."
LUSEX is an AMSAT-LU[4] project AMSAT-LU reports that both satellites are
sending strong telemetry on 70 centimeters. The satellites are being stabilized
over the next few days, and activation of the U/V Amateur Radio transponder
will be announced on the AMSAT Bulletin Board[5].
The transponder, with a 30 kHz bandwidth and transmitting with 250 mW, will
have an uplink passband (SSB, CW) at 435.935~435.965 MHz, and a downlink
passband at 145.965~145.935 MHZ. Basic CW telemetry will be transmitted on
145.900 MHz. The NuSAT-1 GFSK telemetry beacon is at 436.445 MHz, and the
NuSAT-2 GFSK telemetry beacon is at 437.445 MHz.
