Absolute gravity measurement based on laser interferometry is the main means to establish a gravity measurement reference, and it is also the gravity reference instrument used currently. In recent years, along with the development of quantum absolute gravity measurement techniques, new opportunities have been presented for establishing a gravity reference with higher accuracy. With the support of the National Development and Reform Commission, Huazhong University of Science and Technology had established the “PGMF(precision gravity measurement facility)” as a major national scientific and technological infrastructure. A key component of this facility′s construction is the establishment of a micro-Gal level absolute gravity measurement reference station. This station provides a standardized reference for gravity measurement instruments and data, serving as a foundation for achieving high-precision measurements and applications in the gravitational field. High-precision gravity measurement instruments are the core equipment for PGMF to achieve a gravity measurement reference. For this purpose, PGMF independently developed a reference quantum absolute gravimeter suitable for station measurement and a miniaturized quantum absolute gravimeter for reference extension. Furthermore, a gravity comparison field and a background physical environment monitoring system were established. Ultimately, a micro-Gal level gravity measurement reference station was established.
