The present invention discloses a small multi-application-field optical fiber inertial navigation system. A body is of a hollow cubic structure with an inner cavity, three orthogonal optical fiber rings are installed in the inner cavity of the body and on the two side faces of the outer side of the body respectively, and a light source plate and a gyroscope power source plate are installed on the other two side faces of the outer side of the body respectively; the top of the body is provided with a front board, a main board, an AD and a data processing board; and an accelerometer, a power module and a base are installed at the bottom of the body. By adopting the integrated nesting design of different functional modules and the integrated design of software and hardware, the device has the characteristics of small size, light weight and capability of being applied to multiple fields. The problem that an optical fiber inertial navigation system cannot be miniaturized due to device size and shape limitation, system multifunctional requirements and the like is solved.
Description
technical field [0001] The invention belongs to the field of optical fiber inertial navigation, in particular to a small-sized optical fiber inertial navigation system with multiple applications. Background technique [0002] The fiber optic inertial navigation system is based on the principle of inertia and is composed of a fiber optic gyroscope, a three-axis accelerometer and a corresponding computer. It is used to sense the angular velocity and acceleration of the carrier platform. Control System. [0003] On the one hand, due to the large volume and different shapes of the fiber optic gyroscope and accelerometer included in the fiber optic inertial navigation system, the miniaturized inertial system products for military and civilian use have no obvious advantages over MEMS inertial navigation. [0004] On the other hand, in order to meet the background requirements of multi-platform applications, it is necessary for the product to have the function of providing the thr...
