Radio communication and GPS navigation device
First Claim
1. A method of communicating between a plurality of navigation devices comprising:
- obtaining positional information for a first navigation device by assessing a plurality of global positioning satellite signals;
generating a data signal for transmission to a plurality of other devices, the data signal including a latitude value obtained from the positional information for the first navigation device, a longitude value obtained from the positional information for the first navigation device, and an identification of the first navigation device;
transmitting the data signal to a communication device through a signal cable, wherein the communication device is separate from the first navigation device; and
transmitting the data signal, utilizing the communication device, to a plurality of other navigation devices such that each of the plurality of navigation devices can identify and display a geographic position of the first 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.
