Velocity Estimation Using Carrier Phase Measurements of a Global Navigation Satellite System in Autonomous Mode

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].
