Short-term analysis of gnss clocks

Splet01. apr. 2024 · The short-term clock offset prediction accuracy, phase, frequency, fitting residuals, fitting precision, periodic terms, and frequency stability can be obtained. We can evaluate the long-term performance variation of the GLONASS satellite clocks based on the aforementioned indexes. Download : Download high-res image (79KB) Splet04. feb. 2024 · The GNSS clock is a special kind of clock. In normal operation, a GNSS clock employs the GNSS signal to discipline its internal oscillator, making the clock almost as stable as the GNSS system clocks in the long-term. The short-term stability of a GNSS clock is much determined by the quality of its internal oscillator.
