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.
Claims21
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.
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.
1 more element
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.
