Telecommunications Description

A 400 MHz UHF hybrid telemetry system will be used for communication between the penetrators and the orbiter. The penetrator antennae will be 1 to 3 meters below the surface, but lunar regolith is relatively transparent to radio waves. The data transfer rate from the penetrators to the orbiter will be 1 kbit/s and will occur once every 15 days when the orbiter is in position overhead. The orbiter will communicate with Earth by 2 GHz S-band at a rate of 8 kbit/s.
