It is a three unit CubeSat developed for SSB/CW communications in low earth orbit. The VHF/UHF transponder and all other subsystems, except the stabilization, are doubled for redundancy. Where possible, both COTS systems and in-house development is employed.
The energy is provided using lithium polymer batteries together with super capacitors. Satellite stabilization is accomplished using passive magnetic attitude control system with hysteresis rods. The satellite is to include a de-orbiting system which will make it re-enter the atmosphere following completion of its life time. The 3USAT is expected to launch near the end of 2012.
IARU coordinated frequencies are: transponder uplink 145.940-145.990 MHz, downlink 435.200-435.250 MHz and a CW beacon on 437.250 MHz.
