Embodiment Construction
[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0027] Please refer to Figure 1 to Figure 6 Now, the hardware structure of strapdown laser inertial navigation provided by the present invention will be described. The strapdown laser inertial navigation hardware structure includes a box body 100, an outer frame 200, an inner frame 300, and an inner platform 400. The outer wall of the box body 100 is provided with a first indexing mechanism 110 whose output shaft penetrates the box body 100; The frame 200 penetrates in the front-to-rear direction. The outer frame 200 is located in the box 100 and has a second ind...

The invention provides a strapdown laser inertial navigation hardware structure, and relates to the technical field of inertial navigation. The strapdown laser inertial navigation hardware structure comprises a box body, an outer frame, an inner frame and an inner table body, the box body is provided with a first transposition mechanism; the outer frame is located in the box body, a second transposition mechanism is arranged at the bottom of the outer frame, and a first angle measuring shaft system is arranged between the outer frame and the box body; a second angle measuring shaft system is arranged between the outer frame and the inner frame; and an inner table body is arranged in the inner frame. In the strapdown laser inertial navigation hardware structure provided by the invention, amulti-layer modular structure of a box body, an outer frame, an inner frame and an inner table body is adopted; the problem that in traditional arrangement, only the box body is used as a containing part, and consequently space is occupied is solved, the turning radius of the device is effectively reduced, the overall size of the device is reduced, the weight of the device is reduced, and the device has the advantages of being high in interchangeability, convenient to maintain and assemble and suitable for batch production.
Description
Technical field [0001] The invention belongs to the technical field of inertial navigation, and more specifically, relates to a strapdown laser inertial navigation hardware structure. Background technique [0002] With the improvement of the level of technology, the demand for accurate positioning and rapid response of vehicles is also increasing. Inertial navigation systems are used in actual operations. The inertial navigation system is an autonomous navigation system that does not rely on any external information or radiates energy to the outside. It has the advantage of good concealment and can work in various complex environments such as air, ground, and underwater. It is mainly divided into two categories: platform inertial navigation system and strap-down inertial navigation system. [0003] Strapdown laser inertial navigation is a frameless system consisting of three laser gyroscopes, three linear accelerometers and a microcomputer. The laser gyroscope and accelerometer a...
