RADIO COMMUNICATION AND GPS NAVIGATION DEVICE
First Claim
1. A mobile navigation and communication device comprising:
- a global positioning system (GPS) receiver that receives a positional signal from a satellite and determines position information of the navigation device;
a microprocessor in communication with the GPS receiver, the microprocessor configured to receive the position information from the GPS receiver;
the microprocessor further configured to receive voice signals and position information from a plurality of other mobile navigation and communication devices;
the microprocessor further configured to determine a location of the plurality of other navigation devices based upon the received position information from other devices, and;
a liquid crystal display (LCD) in communication with the microprocessor, the LCD providing a display of the location of the plurality of navigation devices relative to the navigation device.

Abstract
A navigation device configured to connect to any type of communication device, such as a two-way radio or a cellular phone. The navigation device includes a LCD display and a user input device. The navigation device displays on the LCD the relative distance and direction of other navigation devices relative to the navigation device, as well as the speed, distance traveled, current location, altitude, temperature of the other navigation devices. Also, the user interface allows the user to scroll through different menu options and display options of the LCD. The navigation device is additionally configured to send text messages to other navigation devices. The navigation device transmits three NMEA sentences allowing text messages, waypoint names and locations, speed, course, direction and altitude to be sent between navigation devices.
