Abstract

The LLR and SLR technologies have been actively developed in recent years. New satellites and very precise measurement systems are appearing currently. This brings the necessity to improve continually the facilities, methods and algorithms which analyze the measurement data obtained [1, 2]. The Main Metrological Center of the State Service of Time and Frequency (MMC SSTF) participates in the scientific and development work to improve the systems for analyzing and evaluating the LLR and SLR data. In 2016, the MMC SSTF upgraded its software for determination of the Earth rotation parameters using the LLR and SLR measurements. New software was developed for the high-orbital and low-orbital satellite orbit calibration using the SLR data and for the very precise positioning of the observational stations. The software for determination of the Universal time based on the LLR observations is nearing its completion. A comparative analysis of the maintenance and test data of the developed software and hardware is presented in this article. It is shown that the accuracy of the results obtained matches the best international standards. It is the evidence of the high scientific and technical level of our work.

AB  - The LLR and SLR technologies have been actively developed in recent
years. New satellites and very precise measurement systems are
appearing currently. This brings the necessity to improve continually
the facilities, methods and algorithms which analyze the measurement
data obtained [1, 2].  The Main Metrological Center of the State
Service of Time and Frequency (MMC SSTF) participates in the
scientific and development work to improve the systems for analyzing
and evaluating the LLR and SLR data.  In 2016, the MMC SSTF upgraded
its software for determination of the Earth rotation parameters using
the LLR and SLR measurements. New software was developed for the
high-orbital and low-orbital satellite orbit calibration using the
SLR data and for the very precise positioning of the observational
stations. The software for determination of the Universal time based
on the LLR observations is nearing its completion.  A comparative
analysis of the maintenance and test data of the developed software
and hardware is presented in this article. It is shown that the
accuracy of the results obtained matches the best international
standards. It is the evidence of the high scientific and technical
level of our work.
