PAIRWISE MEASUREMENTS FOR IMPROVED POSITION DETERMINATION

摘要

Approaches for enhancing range-based position determination using pairwise error detection and compensation are provided. One method for enhancing a position estimate of a first node may include performing measurements at the first node using a signal received from a second node, and receiving measurements from the second node. The received measurements may be performed at the second node using a signal provided by the first node. The method may further include determining pairwise comparisons of the performed measurements and the received measurements, and compensating the measurements performed at the first node, based on the pairwise comparisons, for estimating the position of the first node. Systems and apparatuses for performing the various position determination methods are further presented.

1. A method for enhancing a position estimate of a first node, comprising:
performing measurements at the first node using a signal received from a second node; receiving measurements from the second node, wherein the received measurements are performed at the second node using a signal provided by the first node; determining pairwise comparisons of the performed measurements and the received measurements; and compensating the measurements performed at the first node, based on the pairwise comparisons, for estimating a position of the first node.
