Astronaut / Lunar Lander Link


This link is comprised of a direct sequence spread spectrum (DSSS) transmitter and a sophisticated receiver on-board the lunar lander.  To accommodate non-line of sight comms, passive repeaters are also attached to each of the RFID waypoint flags.  As long as the astronaut places the waypoints in such a way that each waypoint is within line of site of another or the lunar landing module, communications will not be interrupted.
