AVIATION GRAVIMETRIC SYSTEM WITH TRANSFORMER GRAVIMETER
Abstract
The relevance of aviation gravimetric measurements is shown. Advantages and disadvantages of known gravimeters are determined. The purpose of the work is to highlight the methods and means of increasing the accuracy and speed of the aviation gravimetric system. Tasks of the article: to provide the equations of motion and a list of the main components of the system; justify the choice of the natural frequency of the gravimeter oscillations; show the expediency of using the two-channel method to build a gravimeter; conduct an analysis of methodical errors; show the importance of taking into account the correction due to the influence of the angular velocity of the Earth's rotation; to propose and investigate a new transformer gravimeter of greater accuracy than the known ones.
The equations of motion and a list of the main components of the aviation gravimetric system are given. It is substantiated that the selection of the gravimeter's own frequency equal to 0.1 s-1 ensures the absence of the influence of the largest disturbances (vertical acceleration and other accelerations whose frequency is greater than 0.1 s-1) on the operation of the gravimeter and the absence of the need to use additional electronic filters. The expediency of using the two-channel method for the construction of a gravimeter is shown, because this method allows you to compensate for residual instrumental errors. Methodological errors of the measuring system were analyzed. The importance of taking into account the correction due to the influence of the angular velocity of the Earth's rotation is substantiated. To take it into account, it is necessary to make a corresponding correction in the equation of motion of the aviation gravimetric system. The final equation of the measuring system with this correction was obtained. It is substantiated that the use of a new two-channel transformer gravimeter provides the necessary increase in accuracy. The methodical and instrumental errors of the system were analyzed. The accuracy requirements for the components of the measuring system are formulated.
