An amateur radio satellite with HF capabilities is in orbit and operating for the first time in at least 15 years. Two cubesats recently launched by the U.S. Naval Academy - BRICsat (Naval Academy OSCAR-83) and PSAT (NO-84) carry 300-milliwatt PSK-31 transponders with uplinks on 10 meters
The two satellites were launched May 20. They both also operate APRS on VHF (NO-84)/UHF (NO-83), which is not surprising since their design team was led by APRS developer Bob Bruninga, WB4APR.
In a related story, NASA's next mission to Mars, due for launch next year, will include two non-amateur cubesats. According to the AMSAT News Service, it will be the first time these microsatellites have flown in deep space. The ultimate mission goal, in addition to seeing if cubesats can make it through interplanetary space, is to use them as communication relays for future Mars missions between the time a lander enters the planet's atmosphere and touchdown.
