The paper considers the vehicle’s velocity determination using raw carrier phase measurements of GNSS receiver in autonomous mode. This problem is topical for airborne gravimetry 1, because GNSS-derived navigation solutions are essential for it. The idea of the solution is based on differentiating the single differences of carrier phase measurements. The two-step LSM procedure is described. Results from processing the experimental data are analyzed. The paper continues and extends publications 2, 3.
