Improving methods and facilities of Earth’s orientation parameters evaluation in Main metrological center of State service for time, frequency and Earth’s orientation parameters evaluation

Abstract

The results of improvement of methods and facilities of Earth’s orientation parameters in Main metrological center of State service for time, frequency and Earth’s orientation parameters evaluatio in the last five years are considered. The hardware and software are modernized. As result Main metrological center of State service for time, frequency and Earth’s orientation parameters evaluation has program correlator now, the calculation thechnic was improved, Analysis Center of Main metrological center of State service for time, frequency and Earth’s orientation parameters evaluation was created. The Russian metrological institute of technical physics and radio engineering has satellite laser ranging station of new generation now. This station was created by Institute for precision instrument engineering. The new software for satellite laser ranging processing and lunar laser ranging processing was created. The new sofware of the global navigation satellite systems processing was developed. The software for very long base interferometry data processing and software for combination were modernized. Development of evaluation and predictioning facilities of Earth’s orientation parameters Russian metrological institute of technical physics and radio engineering was provided according to modern international direction. This allowed to provide work of evaluation and predictioning of Earth’s orientation parameters at the high international level.
