Data processing and analysis of Xinjiang first order gravity network

Abstract

This paper introduces the technical scheme and process, key links and technologies, adjustment results and accuracy of data processing of Xinjiang first order gravity network. In the data preprocessing of Xinjiang first order gravity network, various corrections are taken into account, and rigorous mathematical models are adopted; in the adjustment, reliable methods and technologies such as “strong and weak benchmark” combined adjustment method and gross error test are adopted, which ensure the accuracy and reliability of the data processing results. After adjustment, the mean square error of all gravity points is ± 17.9×10−8 ms−2, and the mean square error of the weakest point (XJ12 at Turgat station) is ± 30.6×10−8 ms−2. It has positive reference significance and reference value for data processing of regional gravity reference network.
