Multi-constellation transceiver

A satellite terminal comprising:

• an antenna;
• a common port coupled to the antenna;
• a plurality of modems to be switched into and out of use in real-time to allow transitioning between networks via software commands, each of the modems associated with a different satellite constellation, wherein the plurality of modems comprises at least one LEO modem and at least one GEO modem;
• a multi-constellation transceiver, communicably coupled to the antenna via the common port and to the plurality of modems, to route signals between the antenna and to one modem of the plurality of modems, wherein the multi-constellation transceiver comprises:
• a radio-frequency (RF) chain;
• and
• an interface coupled to the RIF chain via at least one communication cable, the interface configured to perform multiplexing and demultiplexing operations between the communication cable and the plurality of modems.

A method comprising:

• switching into and out of use of the plurality of modems in real-time, via software commands, to allow transitioning between networks via software commands, each of the modems associated with a different satellite constellation;
• and
• routing signals between an antenna and individual modems of the plurality of modems an antenna by
• receiving signal from the antenna via a common port and directing those signals to one of the plurality of modems using a multi-constellation transceiver, communicably coupled to the antenna via the common port and to the plurality of modems;
• and
• sending transmit signals, using the multi-constellation transceiver received from the plurality of modems to the antenna via the common port.
