An Apparatus and Method for Determining a Position of an Object
A method (300) and system for determining a position of an object is provided. The method (300) comprises receiving GPS data from two or more satellites (301). An actual signal characteristic associated with the GPS data is then determined (302). A set of signal characteristics being of a same type as the actual signal characteristic is computed (303) from a set of receiver parameters (308). The set of receiver parameters (308) has estimated positions for the object. The actual signal characteristic is compared to the set of signal characteristics of the same type (304) to determine at least one similar signal characteristic from the set of signal characteristics which is substantially the same as or close to the actual signal characteristic (305). The receiver parameters used to compute each of the similar signal characteristics is also determined (306). The position of the object is approximate to one of the estimated positions of the receiver parameters used to compute each of the similar signal characteristics.
