Abstract
A method, computer program product, and system are provided for position estimation in a geo-location system. For example, the method can include receiving a plurality of position measurements from a respective plurality of satellites in a global navigation satellite system. From the plurality of position measurements, a position measurement with a maximum pseudo-range residual value can be selected. A position uncertainty estimate can be determined based on the position measurement with the maximum pseudo-range residual value. Further, a position estimation algorithm can receive the position uncertainty estimate as an input, thereby improving position estimation of the geo-location system.
