Abstract: A method for calculating a position of a receiver. The method includes determining a first position of the receiver at a first time using data from satellites and determining a second position of the receiver at a second time using the first position and data from a non-satellite sensor. The method also includes calculating the positions of the satellites at the second time and comparing, for each satellite, the calculated position with a known position at the second time.
