The invention relates to measuring engineering and can be used for gravimetric measurements on movable basis in geodesy, geology, inertial navigation systems. An aviation gravimetric system for measurements of abnormalities of acceleration of gravity force includes gravimeter, system for determination of current navigation parameters and device for measurement of present height, the outputs of those are connected to the inputs of the airborne computer. The gravimeter is installed on horizontal stabilized platform the axles of which are provided with movers. Two linear accelerometers are included, those are placed on the HSP and connected to the inputs of the ADCM the outputs of which are connected to the inputs of the engines. The sensitive element of the gravimeter is placed in hermetic body and is arranged as the upper and the lower metal plates separated with dielectric. The upper metal plate is connected to the hermetic body through the first insulator. The lower metal plate is connected through the second insulator to springy membrane to which seismic mass is attached. The technical result of the invention is in increase of accuracy of measurements of abnormalities of acceleration of gravity and reliability of aviation gravimetric system. |
