METHOD OF THE OBJECT MOVEMENT PARAMETERS MEASUREMENT AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G01C21/16 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the inertial navigation systems instrument making and can be used to determine the object current angular and linear accelerations. Object movement parameters with the inertial measuring system measuring method, characterized by the arrangement of 9 precision accelerometers in the target object coordinates system, accelerometer readings measurement using the high-speed analog-to-digital converter and computationally effective determination of the object's center of mass angular and linear accelerations in accordance with the calculation formulas. Measuring method implementation system is characterized by fact, that the measuring system mounting frame has box-shaped structure in the form of rectangular parallelepiped with two rigid end plates, on which the accelerometers are installed. Each accelerometer is made in the form of elastic element consisting of two beams-plates of stainless steel. Over the electrical insulation thin layer, on each of beam-plate one side four thin-film strain gauges of nichrome are vacuum deposited, combined into the tensor bridge. At the elastic element free end the inertial mass is fixed. Accelerometer beam-plate shape in the plan is chosen so, that its S-shaped bending under the inertial mass action is provided, which allows to increase the output signal from the strain gauge bridge to reduce the measurement error. By their base the elastic elements are fixed to the common for all accelerometers mounting frame.

EFFECT: increase in the object acceleration determining accuracy, resolution and stability with simultaneous expansion of the operating temperatures range.
