and national legal measurement of technical institutions, is a social welfare-oriented research units. Since its establishment, the China Academy of Weights and Measures has been aiming at the international frontiers of metrology science, and has played an important supporting role in national economic construction, social development and scientific and technological progress, mainly carrying out the following work:<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(i) Carrying out basic research in metrological science, as well as research on the frontiers of metrological technology, measurement theory, measurement technology and methods of transferring and tracing quantitative values.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(ii) Carrying out research on the measurement management system and related regulations, planning and strategic research on the development of metrological science, as well as research on the construction of the national measurement system and the system for the transmission and traceability of quantitative values.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0 (c) Researching, establishing, preserving and maintaining national measurement standards and benchmarks, reproducing unit values and developing nationally important certified standard substances. It studies, establishes and is responsible for maintaining the national time-keeping system. It also carries out work on the transfer of quantitative values and traceability.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(d) Carrying out the international comparison of measurement benchmarks, measurement standards and standard substances to achieve international equivalence. To carry out the domestic work of comparison of quantitative values, to undertake the assessment of measurement and technical institutions, measurement standards assessment and capacity verification, and to undertake the evaluation of the reliability of measurement methods and measurement results.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(E) undertake the National Quality Supervision and Inspection Center, national key laboratories and other technical institutions of the traceability of the value of the work, to undertake type evaluation of measuring instruments and product quality supervision and sampling work.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(f) To carry out research on the traceability system and related technologies in the field of high technology and new development; to carry out research and development of engineering measurement instruments and equipment.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(vii) Undertake the research and revision of relevant international recommendations, international standards and national standards, undertake the formulation and revision of relevant measurement specifications, and carry out the analysis and verification of measurement data and methods.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(viii) to carry out the technical guidance of the statutory measurement of technical institutions, undertake the training of senior measurement professionals.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(ix) Undertake external cooperation and exchanges related to the duties of the Academy.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0(j) Undertake other matters assigned by the General Administration.<\/p><p>\u00a0 \u00a0 \u00a0 \u00a0\u00a0China Academy of Weights and Measures has two campuses, Hepingli and Changping. Among them, the Hepingli compound covers an area of 74,000 square meters, with a building area of 61,000 square meters, which is mainly used for keeping national metrological reference standards and carrying out value transfer services.<\/p><p>\u00a0 T710-GBRO GPS Beidou Rubidium Atomic Clock Constant Temperature Crystal Oscillator Frequency Standard is mainly composed of high-precision timing GPS Beidou receiver, high-performance Rubidium Atomic Clock, low-phase-noise phase-locked crystal oscillator, control module, and low-noise amplifier module. Through the digital phase-locking technology synthesizes the long-term stability of GPS, the low aging characteristics of rubidium atomic clock and the high short stability and low phase noise characteristics of thermostatic crystal oscillator, and innovates a kind of low-phase-noise high-precision atomic frequency standard with both short and long stability and high accuracy. In GPS Beidou lock state, 10MHz frequency stability can reach the performance of ordinary cesium clock, with high cost-effective.\u00a0<\/p><p>\u00a0 T710-GBRO GPS Beidou rubidium atomic clock constant temperature crystal frequency standard output 1PPS signal, is obtained by rubidium atomic clock frequency signal frequency division, and synchronized with the GPS Beidou output UTC time, and GPS Beidou original second pulse compared to the frequency division pulse after smoothing, to overcome the original pulse fluctuations and jumps brought about by the impact of the time base of the UTC is reproduced. When the GPS signal is lost or abnormal, the device can intelligently recognize it and automatically switch to Rubidium Atomic Clock timekeeping mode to continuously provide highly stable time and frequency signals.<\/p><p>\u00a0 T710-GBRO device adopts 3U chassis design, which can output 10MHz, 1PPS and TOD information (option supports multiple 90MHz, 100MHz, 5MHz, 1PPS output). It can be widely used in radar, communication, measurement and calibration, electric power, electronic countermeasures, aerospace measurement and control and other
