System for coordinating the routes of navigation devices
First Claim
Patent Images
1. A method that coordinates navigation devices comprising:
- receiving data at a first navigation device in a first vehicle, receiving navigation data in a second vehicle, where the navigation data comprises data related to a position of a second navigation device, and calculating positional data in the first navigation device based on the received data.

Abstract
Navigational systems direct and coordinate routes through an information exchange. Through processes that monitor position and communicate with mobile ground-based systems, the navigational systems provide users with accurate information about their position and velocity. Locations may be confirmed or derived by computing differences between the time that a signal is sent and the time it is received.

9. A method that coordinates routes of a plurality of navigation devices comprising:
-
transmitting position data of each of the plurality of navigation devices through a network to a host, where the position data includes at least a destination of each route and a position of each navigation device;
determining an intermediate position for each route of the plurality of navigation devices by the host; and
transmitting the intermediate position for each route to the navigation device associated with each route. - View Dependent Claims (10, 11, 12)

13. A navigation device comprising:
-
a position receiver configured to receive and to decode a first signal indicating a position of the navigation device;
a first request signal configured for communication with an external device and external positional data through a communications network;
a confirmation receiver configured to receive and to decode a confirmation signal for communication with the external device, and a second request signal from the external device;
a calculating unit configured to calculate, upon receipt of the confirmation signal by the confirmation receiver, positional data for a route of the navigation device based on the request signal and the external position data; and
a transmitter configured to encode the confirmation signal, the request signal and the positional data, and to send a signal comprising at least one of the request signal and the positional data. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
