Abstract: A computer readable medium containing processor executable instructions configured to perform the steps of (i) monitoring a positional accuracy of location information calculated based on signals received from GNSS satellites, (ii) if the positional accuracy passes a quality check, using the location information to continuously perform a calibration of data received from one or more sensors and (iii) if the positional accuracy does not pass the quality check, cease the calibration of the data received from the sensors, wherein dead reckoning information is calculated from the data received from the sensors.

Abstract: A system includes a processor circuit and a computer readable storage medium. The processor circuit may be configured to plug into an on board diagnostic connector of a vehicle. The computer readable storage medium generally embodies computer executable instructions. The computer executable instructions, when executed by the processor circuit, enable the processor circuit to communicate with one or more busses of the vehicle and to communicate navigational information to an auxiliary device.
