FM Satellite Launch in November

/

RadFxSat (Fox-1B) is scheduled for launch at 01:47 PST (09:47 UTC) on 10th November 2017. RadFxSat is one of four CubeSats making up the NASA ELaNa XIV mission, riding as secondary payloads aboard the Joint Polar Satellite System (JPSS)-1 mission. JPSS-1 will launch on a Delta II from Vandenberg Air Force Base, California.

RadFxSat is a partnership with Vanderbilt University ISDE and hosts four payloads for the study of radiation effects on commercial off the shelf components. RadFxSat features the Fox-1 style FM U/v repeater with a uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. Satellite and experiment telemetry will be downlinked via the “DUV” subaudible telemetry stream and can be decoded with the FoxTelem software.

CAS-4A and CAS-4B Amateur Radio Satellite Transponders Activated

/

The Amateur Radio linear (SSB/CW) inverting transponders on the CAS-4A and CAS-4B satellites were activated on 18th October 2017. CAMSAT’s Amateur Radio payloads piggybacked on the optical remote-sensing micro-satellites OVS-1A (CAS-4A) and OVS-1B (CAS-4B), launched on 15th June 2017.

CAS-4A (call sign BJ1SK) has a CW telemetry beacon on 145.855 MHz, and 4.8 kB GMSK telemetry on 145.835 MHz. The uplink is 435.220 MHz, the downlink is 145.870 MHz (20-kHz passband).

CAS-4B (call sign BJ1SL) has a CW telemetry beacon on 145.910 MHz, and 4.8 kB GMSK telemetry at 145.890 MHz. The uplink is 435.280 MHz, the downlink is 145.925 MHz (20-kHz passband)

RadioStrat - Balloon Based Stratospheric Probe

/

RadioStrat is a balloon-based stratospheric probe project carried on by a bunch of Baccalaureate students as a research work for their final grade.

The four members’ team - Roc, Ignacio, Roger and Carlos, are studying aeronautics, computing and telecommunications within the science and technology branch of the Catalan Baccalaureate in Barcelona.

The probe is based on Arduino Uno and Trackunio. Readings from two temperature sensors and GPS tracking information will be sent to the VHF APRS network. It is expected reach up to 30Km high.

The RadioStrat team contacted to the Catalonia’s Radioamateur Association, Unió de Radioaficionats de Catalunya - URCAT, to get some technical support and to make an agreement to use the radioclub’s callsign EA3URC-9.

The balloon launched on 25th September 2017 (coordinates 41º 42' 51,8'' N i 0º 41' 14,7'' W).
