Cubesats Deployed from ISS

Friday February 28 at 0730Z, several cubesats were deployed from the International Space station.litsat deploy

Perhaps of most interest to radio amateurs are Lithuania’s first satellites, LituanicaSAT-1 and LitSat-1.

LituanicaSAT-1 carries an FM repeater with a 145.950 MHz uplink and 435.180 MHz downlink, a 9600 baud AX25 packet system with a 145.850 MHz uplink and 437.550 MHz downlink, and a CW beacon on 437.275 MHz. Detailed information may be found at http://www.kosmonautai.lt/en/satellite/  and https://www.facebook.com/Lituanicasat1

LitSat-1 carries a linear transponder of unknown bandwidth and with a reported uplink of 435.180 MHz and downlink of 145.950 MHz, a AX25 packet system with a 437.550 MHz uplink and 145.850 MHz downlink. Limited additional information can be found at https://www.facebook.com/palydovas and http://www.space-lt.eu/journeyof-thefirstlithuanian-satellites74326-1-541.html#apacia .

UAPSAT is Peru’s third satellite, and will transmit AX25 packet telemetry and an audio message on 145.980 MHz. It is unclear whether there will be a two-way capability.

ArduSat-2 and SkyCube are also included in this deployment.

University of Louisiana CAPE II Cubesat Designated LO-75

cape-2OSCAR Number Administrator Bill Tynan, W3XO announced the University of Louisiana’s CAPE II cubesat has been designated as University of Louisiana OSCAR 75 or LO-75.

Bill wrote to AMSAT mentor Nick Pugh, K5QXJ, and the CAPE II cubesat team, “I have been able to determine CAPE II has met all of the
requirements for an OSCAR number. By the authority vested in me by the AMSAT-NA president, I hereby issue CAPE II the designation University of Louisiana OSCAR 75 or LO-75. I, and all of the amateur satellite community, wish LO-75 the best of success”.

CAPE II operates on 145.825 MHz with a CW beacon with the callsign W5UL, it also includes a digipeater, text to speech operation, a simplex repeater, email and tweet functions. The ground station software can be downloaded from http://www.ulcape.org

FunCube-1 was recently issued OSCAR designation as AO-73. CubeBug-2 was designated as LO-74.

Orbital launches Cygnus resupply to ISS on Antares rocket, carries new amateur radio satellites

Several new amateur radio satellites were sent to the ISS on the first Commercial Resupply Services (CRS) Cygnus mission from Wallops Island at 18:07UTC January 9th, 2014.

These satellites will be deployed from ISS over the coming weeks, using the NanoRacks CubeSat Deployer from the airlock on the Kibo module of the station. Check back for the deployment announcement.

FUNCube-1 now AO-73, transponder operational during eclipse

FUNCube-1 has applied for and been granted AMSAT Oscar 73 (AO-73). Congratulations to AMSAT-NL and AMSAT-UK!

After a brief periood of testing, AO-73 has been switched to autonomous mode, where the educational beacon runs at 300mw while the spacecraft is illuminated. During eclipse, the beacon runs at low power, and the mode U/V transponder is activated. (If any part of the footprint of the satellite includes a sunlit area, the satellite is illuminated. When the entire footprint is dark, the satellite is eclipsed)

Reports are in that many QSOs have been made, with generally strong signals. It should be noted that until Keplerian elements stabilize, full Doppler CAT tuning may not be very successful. When tuning manually the convention is to tune the higher of the two frequencies, in this case the uplink.

Frequencies are as follows:

• 145.935 MHz BPSK Telemetry 30 or 300 mW

• Inverting SSB/CW transponder 300 mW PEP

– 435.150 – 435.130 MHz Uplink (reports indicate this has shifted~10kHz higher)

– 145.950 – 145.970 MHz Downlink
