23-26

The most perspective gravimeters which work in structure of aviation gravimetrical system is gyroscopic. Nevertheless doublerings in comparison with singlerings dynamically adjusted gyroscopes, have advantages, most powerful of which: higher accuracy and speed, small dimensions, high sensivity. In work it is received the equations of movement new dynamically adjusted gravimeter which will enable to investigate it(him) further, to make mathematical modelling, to define static and dynamic errors.

Gyroscopic gravimeter with digital data processing about acceleration of gravity is considered in a paper. The result of measurement in gyroscopic gravimeter contains errors. An influence gravimeter inertial absolute acceleration and other disturbing influences cause the errors of measurements. These of acceleration arise, for example, by work gravimeter onboard the plane in structure of air gravimetric system. The structural scheme and construction of gyroscopic gravimeter is proposed in a paper for multiple precision. This construction is providing immediate measurements of acceleration of gravity. The possibility to fulfil digital processing and filtration of measuring information in a computing device of gravimeter is appeared also. The possibility of digital data processing is considered in view of a two-dimensional character of an array of measuring information.

W opracowaniu zaprezentowano ideę grawimetrycznego (nie inercjalnego) systemu okreslania pozycjistatku. Omówiono zasade działania systemu oraz budowę i procedury funkcjonowania podsystemów pomiarowych. Dokonano także oceny wymaganej i możliwej do osiągnięcia dokładności pomiarów grawimetrycznych. W podsumowaniu zawarte są uwagi o pewnych zaletach takiego hipotetycznego systemu nawigacyjnego oraz rozważana jest możliwość jego realizacji.

The paper presents an idea of gravimetric )non-inertial) system of making position fixes. Its operational principles are described as well as construction of its mensuration subsystems and procedures of their functioning. The required and achievable accuracy of gravimetric measurements has been discussed. The summary contains remarks about some advantages of this conceivable navigational systems, there is also considered possibly of its realization.
