The miniaturized satellite transceiver is installable in a hand-held device, a mobile satellite transceiver system, or an in-flight transceiver and locator system.

A portable device may also be used, where the portable device may communicate with the vehicle-mountable transceiver and with the transceivers.

Vehicle mounted transmitting and receiving equipment for remote communication with transmitting and receiving equipment in stationary roadside units.

An in-flight radar warning receiver training system (100) for use with a radar warning receiver (RWR) (18) includes a real on/off switch (24) for switching real threat track file data (28) to a formatter (28).

In simple terms, RC planes are controlled with a handheld radio transmitter, which communicates with a receiver aboard the aircraft.

The airborne equipment receives both signals, looks (electronically) at the difference between the two signals, and interprets the result as a radial from the station.

Communication between a drone's remote control and its onboard transceiver also makes a difference when it comes to range.

The variation of the reception frequency received by an on-board receiver due to Doppler shift is reduced, the automatic frequency control (AFC) is facilitated, and the degradation of the quality of the demodulated data is mitigated.

A receiver on an aircraft uses this information to correct GPS signals, which then provides a standard ILS-style display to use while flying a precision approach.
