Abstract
Methods and devices are provided for receiving satellite positioning information at least two different instances from at least one satellite during each respective different instance and calculating a position estimate using received information from the at least two different instances. In some embodiments the invention enables estimation of a position by collecting data from several sets of satellite position signal measurements where an individual set of these measurements may be insufficient to generate an instantaneous position fix. In some embodiments the invention enables the treatment of measurements made of signals from the same satellite, but at different times, as being coincident but originating from satellites in different positions. In some embodiments the invention enables the estimation of a position from measurement signals received in possibly different places, with estimated and/or known relative offsets. In some embodiments the invention enables the use of integrated inertial-sensing equipment to assist a satellite navigation receiver by supplying relative position and velocity data.
