Abstract
Receiver clock modeling is applied for the first time in a multi-GNSS PVT solution based on GPS and GLONASS code and Doppler observations. Besides an improvement in the precision of kinematic heights by 84%, the integrity is strengthened which is especially capital for safety-critical applications, thus solutions are more robust against outliers. For oscillators with high frequency stability, the velocity can also benefit yielding 50% higher precision. Tests with a software receiver show that also real-time applications benefit from this approach and receiver-internal applications can be possible. First investigations on the impact of chip scale atomic clocks on GNSS receiver signal processing show that such oscillators can make the intermediate frequency data noisier compared to the internal oscillator, however, they induce less and smaller systematics.
