Positioning System and Method Thereof
First Claim
1. A positioning system, comprising:
- a Global Navigation Satellite System (GNSS) module, generating a first positioning data according to satellite communication;
a dead reckoning module, estimating a second positioning data according to a measurement data, the first positioning data, and a feedback positioning data of a previous epoch;
a Geographic Information System (GIS) module, fitting the first positioning data to a map to generate a third positioning data taken as a final output of the positioning system; and
a calculating module, deriving the feedback positioning data of a current epoch from the third positioning data and the second positioning data according to predetermined weights, wherein the feedback positioning data is recursively fed back to the dead reckoning module for a next estimation.

Abstract
The invention provides a positioning system. In one embodiment, the positioning system comprises a Global Navigation Satellite System (GNSS) module, a dead reckoning module, a Geographic Information System (GIS) module, and an calculating module. The GNSS module generates a first positioning data according to satellite communication. The dead reckoning module estimates a second positioning data according to a sensor'"'"'s measurement data, the first positioning data, and a feedback positioning data of a previous epoch. The GIS module fits the first positioning data to a map to generate a third positioning data taken as a final output of the positioning system. The calculating module integrates the third positioning data and the second positioning data according to predetermined weights to obtain the feedback positioning data of a current epoch, which is recursively fed back to the dead reckoning module for a next estimation.
