COMBINED GLOBAL POSITIONING SYSTEM RECEIVER AND RADIO
First Claim
1. A communication and navigation apparatus, comprising:
- a navigation receiver for receiving signals from a plurality of sources;
a computing device coupled with the navigation receiver for calculating a location of the apparatus as a function of the received signals;
voice communication equipment for permitting voice communications with another communication and navigation apparatus;
a radio receiver coupled with the computing device for receiving from the other apparatus a radio signal indicative of a location of the other apparatus;
a display coupled with the computing device for indicating the location of the other apparatus; and
a radio transmitter coupled with the computing device for transmitting to the other apparatus a radio signal indicative of the location of the communication and navigation apparatus.

Abstract
A portable GPS/radio unit communicates over a wireless radio network with at least one other unit which is transmitting radio signals over the network indicative of that unit'"'"'s location. The GPS/radio unit comprises a GPS receiver for receiving satellite signals from a plurality of satellites, a radio receiver for receiving the radio signals transmitted by the other unit, a processor for calculating the unit'"'"'s location as a function of the received satellite signals and for identifying the location of the other unit based on the received radio signals, and a display for indicating the location of the other unit. The display may indicate the respective locations of multiple units and may also display unique identifiers for each of the units. A system and method for indicating the location of one portable GPS/radio unit on the display of another portable GPS/radio unit involves at least two such units communicating with one another over a wireless radio network.
