Abstract: This paper presents an original technique based on pseudo-acceleration measurements to compute a fix with a global navigation satellite system (GNSS) spaceborne receiver. The pseudo-acceleration measurements can be computed by pseudorange differencing, and the relation between the position and the acceleration is given by Newton’s law. Then, a least-squares system resolution makes it possible to obtain the state of the receiver (position, velocity, clock bias, and drift) when only two emitters are visible in a low earth orbit (LEO) configuration, and when these data are adapted to geostationary earth orbit (GEO) orbits, one can obtain the state of the receiver when only one GNSS emitter is visible.
