摘要

Abstract—The article is devoted to compiling maps of Earth’s gravitational field (EGF) parameters using measurement data from gravimetric equipment, including a plumb line deviation (PLD) meter (astrometer) and a high-precision relative gravimeter. Joint area measurements using the apparatus makes it possible to determine the following EGF parameters: acceleration due to gravity and gravity anomalies, the components and total PLD, and the components of acceleration due to gravity and gravity gradients (second derivatives of the anomalous potential). The total measurement time at a single point using the apparatus does not exceed 1 h, the standard deviation of the PLD component measurement series is from 0.1″ to 0.3″, and acceleration due to gravity is 10 μGal. The paper presents examples of maps of these EGF parameters, compiled from the measurement results using the gravimetric apparatus on the territory of Moscow oblast, including a measurement profile across the Moscow gravity anomaly.
