A system for communications on an extraterrestrial body may include a space-based component and an ancillary extraterrestrial component on the extraterrestrial body. The space-based component may be configured to provide wireless communications with a plurality of radioterminals located on the extraterrestrial body over a satellite frequency band wherein the space-based component includes at least one satellite orbiting the extraterrestrial body. The ancillary extraterrestrial component may be configured to provide wireless communications with the plurality of radioterminals located on the extraterrestrial body. Moreover, the ancillary extraterrestrial component may reuse at least one satellite frequency of the satellite frequency band, and the space-based component and the ancillary extraterrestrial component may be configured to relay communications therebetween. Related methods are also discussed.

Communications systems and methods including emission detection

A radioterminal includes a wireless communications transceiver, a GPS receiver and a controller. The controller is configured to authorize at least one other radioterminal to receive geographic position information of the radioterminal, to activate the GPS receiver to obtain a measure of a geographic position of the radioterminal and to activate the wireless communications transceiver to transmit the measure of the geographic position of the radioterminal to the at least one other radioterminal that was authorized, responsive to a rate of change of position of the radioterminal. Related methods also are described.

Radioterminals and associated operating methods that transmit position information responsive to rate of change of position

A radioterminal includes a wireless communications transmitter, a wireless communications receiver and a GPS receiver. A controller is configured to enable the GPS receiver when the wireless communications receiver is receiving wireless communications, and to disable the GPS receiver when the wireless communications transmitter is transmitting wireless communications. Related methods also are described.
