A system of devices both capable of receiving civilian GPS signals, but also capable of providing a relative distance and direction indication that is accurate to several meters. A first device would be capable of transmitting its GPS determined position to a second device. The second device would include a means for receiving the GPS determined position of the first device, and would also include means for calculating the relative distance and direction between the first and second devices. The system would further include the ability of the first device to selectively transmit telemetry at a desired frequency. By providing the second device with the ability to selectively tune a receiver to receive a telemetry signal broadcast by different devices, a distance and direction to a plurality of first devices is possible.

A relative position indicating system comprising: a first GPS receiver including means for receiving a plurality of GPS signals from different sources and means for determining a geographical location of the first receiver; a transmitter associated with the first GPS receiver for sending telemetry data as to the geographical location of the first GPS receiver; a second GPS receiver including means for receiving a plurality of GPS signals from different sources and means for determining a geographical location of the second receiver; receiver means associated with the second receiver for receiving the telemetry data from the first GPS receiver; calculating means associated with the second GPS receiver for comparing the geographical locations represented by the first GPS receiver telemetry data and the geographical location determined by the second GPS receiver, and for calculating an approximate direction, a distance, and a relative height variance between said first GPS and said second GPS receivers; and a display associated with the second GPS receiver for indicating the approximate distance, the direction and the relative height variance between the first GPS and the second GPS receivers.
