Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. One or more non-transitory computer-readable storage media storing computer-executable instructions that upon execution cause one or more computers to collectively perform acts comprising:
receiving at least one signal measurement from a position consumer device;
using the at least one signal measurement in a trilateration method to estimate a position of the position consumer device in a fingerprint map;
using one or more threshold values to filter reference data points in the fingerprint map that are near an estimated position of the position consumer device;
selecting a pair of reference data points with associated signal measurements that bracket the at least one signal measurement from the position consumer device;
interpolating the pair of reference data points;
determining whether an interpolated pair of reference data points are collinear with the estimated position of the position consumer device; and
calculating a location of the position consumer device based on geo-locations of position source devices associated with collinear reference data points.
