A communications link having a position capability responsive to either a manual or remote control actuation. In one embodiment, a remote carrier has a navigation system for outputting signals representative of the carrier location or position. A frequency shift key (FSK) modulator is connected to the navigation system for tone coding the carrier position signals, a transmitter of a transceiver is connected to the modulator for transmitting the carrier position signals, and a position enable switch for controlling selectively the transmittal of the carrier position signals. In another embodiment, a base station is provided with a control station identification signal (ID) generator, an FSK modulator for tone modulating the station identification signal, and a transmitter connected to the FSK modulator for transmitting the tone modulated carrier ID signal, and a remote station is provided with a receiver mounted upon the carrier for receiving the ID signal, said receiver having a demodulator for demodulating the received carrier identification signals, means for recognizing the ID signal, enabling means for enabling a transmitter, a navigation system outputting position information, an FSK modulator connected to the navigation system for tone modulating the carrier position information, a transmitter for transmitting the position information, and in the base carrier a printer having an FSK demodulator connected to the receiver for demodulating and printing the carrier position information.
