Purpose of the development: It designed and manufactured acting Pilot sample of geo-navigation system based on three-compact integrated micromechanical sensors (MEMS) for use in unmanned aerial vehicles.

Technical characteristic: The base module is adapted in diameter 33 mm and length 400 mm.

Advantages over analogues: Maximum accuracy of the measured parameters and performance several times higher than that of counterparts.

The development stage readiness: tested in laboratory condition

Technical and economic effect: The cost of the navigation module of the domestic development and production is several times lower than the known foreign analogues. In addition Apparatus and software can be adapted if necessary on their own (without the participation of foreign companies) to new challenges.

Description of the development:
()
The measuring unit created module consists of accelerometers, magnetometers, and a hemispherical resonator gyro. Appearance primary converters inclinometer: a) three-magnetometer industrial performance; b) an accelerometer - a differential capacitive sensor of the original performance; c) a hemispherical resonator gyro - angular rate sensor of industrial performance. The use of such a scheme of sensors allows duplicate measurement of angular parameters of two independent systems registration. As a micromechanical gyroscope sensor type used CRS05-01 (Silicon Sensing). Laboratory testing and calibration of the measuring system were conducted on a special gyroscopic stand. We analyzed the data stability control device parameters over time and at different temperatures. Sensor test results in a variation of the temperature possible to trace a certain tendency to drift in the MEMS-devices and to develop recommendations for temperature stabilization gyro unit converter. Analysis of the possible errors of calibration (as a result of nonlinear dependence of the sensor output signal from the angle) and temporal stability readings gyro sensor under the influence of temperature variations and dynamic impact loads showed principal possibility to ensure the accuracy of determining the azimuthal orientation of the borehole at ± 15 ° C for one hour measurements after device in operation. Zenith angle accuracy is ± 0.2 ° in the entire range of its dimensions. Accuracy apsidalnoi orientation angle (viewing angle) depends on the zenith angle and ranges from 10 ° ± 2 °.
