PORTABLE MOBILE TRANSCEIVER FOR GPS NAVIGATION AND VEHICLE DATA INPUT FOR DEAD RECKONING MODE
First Claim
1. A method for implementation on a mobile transceiver device, comprising:
- determining a position of a mobile transceiver device based on received GPS signals; and
responsive to detecting GPS signal reception inadequate to update the position of the mobile transceiver device, using dead reckoning inputs received from a vehicle in which the mobile transceiver device is located, in conjunction with a last GPS determined position, to provide an estimated position of the vehicle, for use in producing a navigation output.

Abstract
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.

12. A mobile transceiver device, comprising:
-
a receiver module for receiving a plurality of signals from which a position can be determined, and for producing a navigation output based on the received plurality of signals, wherein the receiver module may fail to calculate a current position at times; a microprocessor; and a memory storing code for configuring the microprocessor to receive, from the receiver module, the current calculated position, when available, and use the current calculated position in providing a navigation output through a user interface of the mobile transceiver device, and receive dead reckoning inputs from an interface to an automobile data system, during one or more times when the receiver module fails to output the current position, and to use the dead reckoning inputs in estimating the current position of the mobile transceiver device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A computer readable medium storing computer executable code comprising code for programming a microprocessor located in a mobile transceiver device to
dynamically switch from GPS-based navigation to dead reckoning navigation, during times when a position of the mobile transceiver device is not sufficiently determinable based on received GPS signals; -
perform the dead reckoning navigation based at least on one or more inputs received from a data system of an automobile with which the mobile transceiver device is moving; and dynamically switch from dead reckoning based navigation to GPS-based navigation upon availability of an updated GPS-based position fix. - View Dependent Claims (21)

22. A method for providing navigation outputs from a mobile transceiver device, comprising:
-
outputting, from a user interface of the mobile transceiver device, navigation information determined based on using a position determined using received GPS signals, when GPS signals are available; and outputting, from the user interface of the mobile transceiver device, navigation information determined based on one or more dead reckoning inputs received from a data system of an automobile, in which the mobile transceiver device is located, when GPS signals are unavailable. - View Dependent Claims (23)
