GB/T 20256-2019 Specifications for the gravimetry control
Abstract
This standard specifies the principles for establishing gravity control networks (points) across the country, absolute gravity measurement, relative gravity measurement, plane coordinate and elevation determination, data processing, and acceptance inspection of results, among other aspects.
This standard is applicable to the construction of national gravity control networks, and the measurement of reference points, basic points, first-order points, and corresponding tie points.
