Abstract:
The present invention provides an integrated navigation system and its positioning method, and it pertains to the technical field of satellite navigation. The integrated navigation system of the present invention comprises a GNSS resolving module, an integrated navigation filter and an auxiliary navigation module using a sensor, wherein the auxiliary navigation module outputs corresponding positioning and/or orientation measurements to the integrated navigation filter; the GNSS resolving module is able to output the floating point solution or single point solution; the integrated navigation system further comprises a smoothing filter provided corresponding to the GNSS resolving module, which is configured to perform a smooth filtering processing on the floating point solution or single point solution to obtain smooth floating point solution or smooth single point solution respectively; the integrated navigation filter is configured to perform integrated filtering on the received smooth floating point solution or smooth single point solution and the corresponding received positioning and/or orientation measurements to obtain the corresponding positioning and/or orientation variable error estimate and sensor error estimate. The integrated navigation system of the present invention has high positioning accuracy and low implementation cost.

Claim (Index 17):
The positioning method according to  claim 12 , wherein the fixed solution is obtained by resolving according to the qualities of the received satellite signals,\n and an integrated filtering processing is performed to the received fixed solution and the corresponding received positioning and/or orientation measurements so as to obtain the corresponding positioning and/or orientation variable error estimates and sensor error estimate, or calculating said positioning and/or orientation variable error estimates corresponding to the fixed solution and the corresponding received positioning and/or orientation measurements in combination so as to obtain a corresponding integrated fixed solution.
