Abstract
Systems and methods for estimating error associated with one or more range measurements that are used to estimate the position of a receiver. Estimations of range error may be based on surveyed range errors associated with locations near the position of the receiver. Estimations of range error may alternatively be based on comparisons of actual movement by the receiver to estimated movement between estimates of the receiver's positions.
