Problems solved by technology

The conductive slip ring connection increases the volume of the system, increases the cost and power consumption of the system, and requires regular maintenance. The conductive slip ring is worn, which reduces the reliability and service life of the system.
However, the rotating structure directly connected by wires needs to design a mechanical limit mechanism, which increases the volume and cost of the system, and cannot realize the function of continuous rotation, which reduces the effect of rotation modulation. Low-precision micro-mechanical gyroscope applied to gyro-inertial north finder

Abstract

The invention provides a micromechanical gyro north seeker. The micromechanical gyro north seeker based on a rotation modulation technology employs wireless power supply and wireless communication transmission, has a built-in integral structure, and realizes wireless communication and wireless power supply between a digital signal acquisition plate and a digital signal processing plate. Compared with the prior art, the micromechanical gyro north seeker based on a rotation modulation technology saves a conductive slip ring and a mechanical spacing mechanism by employing the built-in integration design, and volume and cost of the seeker are substantially reduced.

Description

technical field [0001] The invention relates to a micromechanical gyro north finder, in particular to a portable low power consumption micromechanical gyro north finder based on rotation modulation technology, which belongs to the technical field of inertial north seeker. Background technique [0002] As an instrument for indicating azimuth, the north finder is not only widely used in the high-tech fields of national defense such as satellites, missiles, and high-precision inertial navigation systems, but also in geophysical exploration, coal mining, geodesy, mines, It is widely used in civil fields such as underground drilling engineering, tunnel excavation, unmanned vehicle automatic driving system, and vehicle positioning and directional navigation system. [0003] According to different principles, north finders are divided into two categories. The first type of north finder requires the assistance of external information, such as astronomical north finding, GPS north f...
