ALWAYS-ON SATELLITE POSITIONING RECEIVER

A method for establishing a position of a device is disclosed. The method generally includes the steps of (A) receiving an input signal from a receiver listening to a plurality of satellites in a positioning system, (B) calculating (i) a plurality of estimated Doppler shifts of the satellites, (ii) an estimated position of the device and (iii) an estimated velocity of the device, (C) generating a plurality of pseudo-ranges in an intermediate signal based on all of (i) the input signal, (ii) the estimated Doppler shifts, (iii) the estimated position and (iv) the estimated velocity and (D) generating the position in an output signal based on the pseudo-ranges.
