Zusammenfassung:	Systems and methods are provided for providing reliable positioning data for a vehicle. Satellite positioning data is determined using a satellite positioning module. Based on the satellite positioning data, a first dead reckoning module is periodically reset at a first interval and a first dead reckoning module is periodically reset at a second interval offset from the first interval. The satellite positioning data is compared to first dead reckoning positioning data of the first dead reckoning unit and to second dead reckoning positioning data of the second dead reckoning unit, and the satellite positioning data, the first dead reckoning positioning data, or the second dead reckoning positioning data is selected as a vehicle position based on the comparison.
