Patent ID: 8242955

Claim:
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: a position dilution of precision metric for each of said series of matching position fixes; a carrier lock duration metric for each of said series of matching position fixes; an estimated accuracy metric for each of said series of matching position fixes; and a summed total metric for each of said series of matching position fixes; and 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.
