First Claim
1. A portable GPS/radio unit capable of communicating with at least one other portable GPS/radio unit over a wireless radio network, the GPS/radio unit comprising:
- a GPS receiver for receiving satellite signals from a plurality of satellites;
a processor coupled with the GPS receiver for calculating a location of the GPS/radio unit as a function of the satellite signals;
a radio transceiver coupled with the processor and operable for transmitting voice communications to and receiving voice communications from the other GPS/radio unit, and transmitting a radio signal to the other GPS/radio unit indicative of the location of the GPS/radio unit and receiving from the other GPS/radio unit a radio signal indicative of a location of the other GPS/radio unit; and
a display coupled with the processor and operable for displaying an indication of the location of the GPS/radio unit, an indication of the location of the other GPS/radio unit, and an indication of a distance between the GPS/radio unit and the other GPS/radio unit, wherein the indication of the distance between the GPS/radio unit and the other GPS/radio unit comprises a plurality of radii rings surrounding the indication of the location of the GPS/radio unit, wherein each of the radii rings is representative of a particular distance from the GPS/radio unit, and wherein the distance represented by each radii ring and a number of radii rings displayed may be selected and changed.

Abstract
A portable GPS/radio unit (10) communicates over a wireless radio network (12) with at least one other such unit (10A-10E). The unit (10) may transmit radio signals over the network (12) indicative of the unit'"'"'s location and receive similar radio signals from other such units. The unit (10) is operable to display an indication of the distance between two or more units, an indication of the amount of time that has elapsed since location data was last received from another unit, a track log or track back information for another unit, and an indication if the unit (10) is about to lose communications with another unit. The unit (10) also may be operated to gather and transmit to other units location data corresponding to way points. The perspective or vantage point from which location data and other information is viewed may be selected or changed by the user of the unit (10).
