Purpose of the development: The geonavigational module is intended for use as part of downhole instruments: cable or relieves mine inclinometers for continuous measurement of the angular parameters of the well profile when drilling or repairing it.

Recommended application field: Mining.

Technical characteristic: - zenith: 0 - 180 ° ± 0.1 °; sighting: 0 - 360 ° ± 0,5 °. - azimuthal: 0 - 360 ° ± 0,5 ° (magnetometer) drift of MEMS goniometer - 15 ° / hour. Output data - digitally via - an asynchronous serial port. Temperature range: -20 ... + 85 ° С.

Advantages over analogues: The advantage of the proposed module is that due to its special application in a limited range of zenith angles, the design is greatly simplified, the absence of electromechanical assemblies improves reliability.

The development stage readiness: Ready for application

Description of the development:
()
The geonavigational module consists of two units: a submodule of a uniaxial goniometer (solid-state analogue of a gyroscope) based on the wave microelectromechanical systems (MEMS) and a submodule of a triaxial magnetogravitational goniometer, which together allow to measure the position of a slaughtering instrument-the zenith, sight and azimuth angle in cased and uncased parts wells when drilling or repairing. Vibration-resistant. Allows to build wells of inclinometers for operation both in the Earth's magnetic field and in its absence in vertical cased steel pipes.
