Гравиметр для измерения силы тяжести с движущихся носителей, содержащий гиростабилизированную платформу (ГСП) с установленными на ней гироскопом, оси чувствительности которого совпадают с осями платформы, акселерометрами, оси чувствительности которых совпадают с осями платформы, гравиметрическим ЧЭ (ГРЧЭ), ось чувствительности которого перпендикулярна плоскости платформы. Гравиметр содержит также корректирующее устройство, входы которого подключены к выходам акселерометров, а выходы - к входу датчиков момента, и гравиметрический фильтр, вход которого подключен к выходу гравиметрического ЧЭ, и усилители стабилизации, входы которых подключены к выходам датчиков угла гироскопа, а выход - к исполнительным устройствам следящих систем стабилизации. Изобретение направлено на повышение точности калибровки масштабного коэффициента гравиметрического ЧЭ (ГРЧЭ) благодаря обеспечению возможности калибровки ГРЧЭ без его демонтажа, а также определения неперпендикулярности оси чувствительности ГРЧЭ плоскости ГСП. Для этого на ГСП установлены индикаторы фиксированного наклона ГСП вокруг ее осей, а в состав гравиметра включен блок калибровки, причем выходы индикаторов подключены к свободным входам корректирующего устройства, а вход блока калибровки подключен к выходу ГРЧЭ.Gravimeter for measuring gravity from moving carriers, containing a gyrostabilized platform (GSP) with a gyroscope installed on it, the axes of sensitivity of which coincide with the axes of the platform, accelerometers, the axes of sensitivity of which coincide with the axes of the platform, gravimetric sensitive element (HRCHE), the axis of sensitivity of which is perpendicular to the plane platforms. The gravimeter also contains a correction device, the inputs of which are connected to the outputs of accelerometers, and the outputs - to the input of torque sensors, and a gravimetric filter, the input of which is connected to the output of a gravimetric sensitive element, and stabilization amplifiers, whose inputs are connected to the outputs of the gyro angle sensors, and the output to to executive devices of the tracking stabilization systems. The invention is aimed at improving the accuracy of calibration of the scale factor of gravimetric chae (SEE) by providing the possibility of calibrating HRTU without dismantling it, as well as determining the non-perpendicularity of the axis of detection of the EPTA of the SHG plane. For this purpose, indicators of fixed GPS inclination around its axes are installed on the GPS, and a calibration unit is included in the gravimeter, the indicator outputs are connected to the free inputs of the correction device, and the input of the calibration unit is connected to the HRCH output.
