POSITION DETERMINATION BASED ON CORROBORATED SIGNAL PROCESSING OF PRN CODES
First Claim
1. A navigation satellite system (NSS) method for position determination based on signal processing of PRN codes, the method comprising:
- using a NSS high yield signal processing technique for determining a high yield location solution using a first set of PRN codes;
using a NSS high accuracy technique for attempting a high accuracy location solution based on signal processing of said first set of PRN codes, andselecting the high accuracy location solution as a NSS-based location when the high accuracy location solution is available and selecting the high yield location solution for the NSS-based location when the high accuracy location solution is not available and the high yield solution is available.

Abstract
Embodiments provided herein recite methods and systems for corroborating position system code from Navigation Satellite System (NSS) signals. In one embodiment, a NSS high yield module attempts to determine a high yield location solution based on a first set of PRN codes. In addition, a NSS high accuracy module attempts to determine a high accuracy location solution based on signal processing of the same first set of PRN codes. A location solution corroborator module receives input from both the NSS high yield module and the NSS high accuracy module and generates a corroborated location solution. In one embodiment, a position provider outputs the corroborated location solution.
