Claim Text:
1. A method of calculating a position of a receiver, the receiver including a position calculating device, the method comprising: receiving, by the position calculating device, respective satellite signals from a plurality of satellites at the receiver; deriving, by the position calculating device, satellite information, including a satellite position and a satellite velocity corresponding to each of the plurality of satellites at an instant of time; and calculating, by the position calculating device, the position of the receiver using a set of equations, the set of equations including an equation for each satellite representing a time error of a time counted by a local clock of the position calculating device, the time error being equal for each of the satellites, wherein the equation for each satellite representing the time error is a function of at least the corresponding satellite information, a pseudo distance calculated from the corresponding satellite signal at the receiver, a relative speed vector between the receiver and each satellite, and a clock bias of the local clock.
