PERFORMANCE ENHANCEMENTS FOR LOCAL NETWORK OF BEACONS

摘要

Systems and methods for estimating a position of a receiver within a venue using localized networks of beacons. Certain aspects relate to different configurations of networks. Other aspects relate to estimating the position of the receiver when the receiver approaches an edge of a localized network of beacons.

1. A method for estimating one or more positions of a receiver in a network of beacons, the method comprising:
determining a first position estimate of a receiver based on a first set of range measurements corresponding to a network of beacons; setting a current position of the receiver to the first position estimate; determining a second position estimate of the receiver based on a second set of range measurements corresponding to the network of beacons; determining whether the second position estimate is within a predefined area associated with the network of beacons; when the second position estimate is inside the predefined area:
setting the current position of the receiver as the second position estimate; and when the second position estimate is not inside the predefined area:determining a third position estimate of the receiver based on the first position estimate and a first measurement of velocity associated with a first movement of the receiver, andsetting the current position of the receiver as the third position estimate.
