Abstract
Estimating range bias in a timing-based radio positioning network. Systems and methods estimate range bias, and use the estimated bias to adjust an estimated range measurement for use in estimating a position of a receiver. Estimated range bias may be based on surveyed range errors associated with locations near the position of the receiver, or may alternatively be based on comparisons of different range measurements.
