Patent

CA 2729410

A mobile transceiver device comprises a GPS receiver module to receive GPS signals and calculate current positions. The current positions are used in a navigation module. The mobile transceiver device comprises one or more local interface technologies, such as Bluetooth and USB. These local interface technologies can be used to communicate with an automobile data system. In situations where there is sporadic GPS coverage, the mobile transceiver device receives inputs from the automobile data system, such as speed or velocity information, and heading information, such as output from a compass, as available. These inputs are used in the navigation module of the mobile transceiver device to navigate by dead reckoning until an updated position fix based on received GPS signals can be calculated.
