Multiple amateur satellites deployed from ShuttleANDE, RAFT and NMARS were deployed from the Space Shuttle on 21 December 2006. RAFT and NMARS have a very high spin rate. NMARS is spinning at at least 60 RPM and RAFT at maybe half that. This will make getting a complete 1 second packet difficult due to fading on linear antennas. The Naval Research Laboratory science mission of ANDE is to measure the density of the upper atmosphere by precise tracking of the orbit decay by the Maui Laser Ranging Tracking Station. The Comm system provides important telemetry on the attitude and temperature of the spacecraft. RAFT carries a 216.98 MHz receiver/transmitter to demonstrate self-location techniques when it flies through the Space Surveillance Network radar fence across the southern USA. When this experiment is activated, users will hear a 1 second ping when it flies through the fence. ANDE and RAFT also carry packet radio communications systems and join with other US Naval Academy APRS digipeating satellites such as PCSAT-1 and PCSAT2. ANDE and RAFT will respond to the path alias of APRSAT and ARISS. This is so that users do not have to reconfigure their path between satellites or between their ISS groundstation. The following frequencies are used by these two spacecraft: Much more information about these satellites is available on the ANDE,
RAFT, NMARS, & FCAL Operations web site.
