TECHNIQUES TO IMPROVE THE PERFORMANCE OF A FIXED, TIMING-BASED RADIO POSITIONING NETWORK USING EXTERNAL ASSISTANCE INFORMATION |
摘要 |
Described are 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 for nearby position estimates. Estimations of range error may alternatively be based on comparisons of actual movement of a receiver to estimated movement between two position estimates. |

1. A method for estimating error associated with one or more range measurements, the method comprising:
determining a first set of range measurements using a first set of ranging signals received at a first position in a transmitter network; determining one or more range error adjustments that are associated with a second set of range measurements from a second set of signals received at a second position in the transmitter network; and estimating the first position using the first set of range measurements and the one or more range error adjustments that are associated with the second set of range measurements. |
