Abstract

When analyzing the GNSS performance, constant monitoring and operational confirmation of precision characteristics of onboard atomic frequency standards and the accuracy characteristics of the time-frequency support are required. The main accuracy characteristic is the accuracy of determining the satellite clock time scale corrections for the offset between the onboard satellite time scale and the GNSS system time scale. To this end, the authors have developed a comprehensive approach to assessing the characteristics of onboard frequency standards, the accuracy of satellite clock time offset predictions, and performed a comparative analysis of data from various sources. The results are presented of assessing the accuracy of predicting corrections to onboard time scales available through the navigation signal of satellites of systems GLONASS, GPS, Galileo and BeiDou. The results obtained make it possible to qualitatively analyze the state of atomic frequency standards during operation with inputs from various data centers, to compare various GNSS characteristics, to improve the methods for predicting satellite time clock offset, which can result in improving the performance of the GLONASS system.

AB  - When analyzing the GNSS performance, constant monitoring and
operational confirmation of precision characteristics of onboard
atomic frequency standards and the accuracy characteristics of the
time-frequency support are required. The main accuracy characteristic
is the accuracy of determining the satellite clock time scale
corrections for the offset between the onboard satellite time scale
and the GNSS system time scale.  To this end, the authors have
developed a comprehensive approach to assessing the characteristics
of onboard frequency standards, the accuracy of satellite clock time
offset predictions, and performed a comparative analysis of data from
various sources. The results are presented of assessing the accuracy
of predicting corrections to onboard time scales available through
the navigation signal of satellites of systems GLONASS, GPS, Galileo
and BeiDou.  The results obtained make it possible to qualitatively
analyze the state of atomic frequency standards during operation with
inputs from various data centers, to compare various GNSS
characteristics, to improve the methods for predicting satellite time
clock offset, which can result in improving the performance of the
GLONASS system.
