Radar Fence Transponder (also called Navy-OSCAR 60 or RAFT 1) was an
RAFT contained a receiver at 216.98
Two fixed antennas equipped with springs were used for communication and also as a separation system for the almost identical sister satellite MARScom. Furthermore, a 122 cm (48 in) long wire antenna made of 0.5 mm (0.020 in) nitinol wire for the 10 m amateur radio band was unwound on shortwave during the disconnection process, with which the satellite received signals in the PSK31 operating mode.[3]
Mission
The satellite was released on 21 December 2006 with Space Shuttle Discovery (STS-116) from Kennedy Space Center, Florida.
On 30 May 2007, it was re-entered on
