Abstract:
1. A method for providing an improved accuracy estimate of a position fix, the method comprising: calculating, at a global navigation satellite system receiver, a series of matching position fixes for a given epoch utilizing an L1 code solution technique and at least one of a plurality of solution techniques selected from the group of solution techniques consisting of: an L1/L2 fixed-integer static solution technique, an L1/L2 fixed-integer kinematic solution technique, an L1 fixed-integer static solution technique, an L1 fixed-integer kinematic solution technique, an L1/L2 float static solution technique, an L1/L2 float kinematic solution technique, an L1 float static solution technique, and an L1 float kinematic solution technique; computing, at said global navigation satellite system receiver, a table of metrics for each of said series of matching position fixes for said given epoch, said table of metrics including at least: utilizing, at said global navigation satellite system receiver, said table of metrics as associated accuracy metrics for estimating accuracies of said series of matching position fixes in comparison to one another.
