Introducing the Principle of Constructing an Aviation Gravimetric System with Any Type of Gravimeter

Measurements of parameters of the Earth's gravitational field from aircraft are the most important because they make it possible to carry out measurements in the zones of poles areas the Earth, the equator, mountain ranges and other hard to reach areas of the Earth. Studying these parameters is necessary for the exploration of mineral resources, forecasting earthquakes, tsunamis, etc.We put forth general principles for constructing aviation gravimetric system (AGS) with any type of gravimeter. A list of basic components of AGS is compiled: gravimeter of any type, system for determining navigation parameters, altitude gauge, and onboard computing machine. We analyzed methodological errors of the system. Precision requirements to the components of AGS are formulated, provided the accuracy of AG measurements is 1–2 mGal. The choice of natural oscillation frequency of the AGS gravimeter is substantiated, which is 0.1 s-1. The equation is derived that takes into account correction from the impact of angular velocity of the Earth rotation. We substantiated the application of a dual-channel method to construct an AGS gravimeter. Expedience of employing neural networks is demonstrated to eliminate instrumental errors of the AGS gravimeters
