CubeSat FM Repeater SatCOM FMTP

CubeSat FM Repeater SatCOM FMTP

SatCOM TP0 is a high-quality FM repeater for small satellites, designed by NanoAvionics’ partner LY3H. It is fully pre-programmed and configured prior to shipment according to customer request. No dedicated power-on signal is required, the device is either ON or OFF state and is ready for operation immediately after turning on.

Right after the repeater is activated a voice/CW message is transmitted once. Later the message is transmitted repeatedly every 4 minutes if uplink (CQ) signal is detected. The repeater can share single reception antenna with other receivers working on a similar band through a passive, therefore highly reliable electronic splitter circuit.
