AIRCRAFT GRAVIMETRIC SYSTEM FOR MEASUREMENT OF ANOMALIES OF GRAVITATIONAL ACCELERATION

摘要

The invention relates to measuring engineering. An aircraft gravimetric system for measurement of anomalies of gravitational acceleration includes a system for the determination of current navigation parameters, device for measurement of current elevation and gravimeter which outputs are connected to airborne digital computing machine (ADCM). The gravimeter of the aircraft gravimetric system is installed on a biaxial platform which axles are provided with two motors. The sensitive element of the gravimeter is placed in hermetic body and is arranged as a piezoelectric cell fixed on a rod, on the free end of that one inertial mass is placed. On the biaxial platform two linear accelerometers are placed, those are connected to the inputs of the ADCM to which outputs motors are connected. The invention makes it possible to increase accuracy and reliability of aircraft gravimetric system for measurement of anomalies of gravitational acceleration.
