Description

Technical Field

[0001] This utility model relates to the field of inertial navigation testing technology, and in particular to an inertial navigation batch testing fixture. Background Technology

[0002] Inertial navigation testing refers to the process of testing the performance of an inertial navigation system. An inertial navigation system is an autonomous navigation system that does not rely on external information or radiate energy externally. It primarily relies on gyroscopes and accelerometers to sense navigation parameters and calculate the velocity and position of the vehicle. The main purpose of inertial navigation testing is to verify the performance of the inertial navigation system and ensure its accuracy and reliability under various operating conditions.

[0003] In the prior art, patent document with publication number (CN214445698U) mentions an inertial navigation batch testing fixture, including a base plate, a clamping plate, and a cover plate. The cover plate fixes the clamping plate to the base plate, and a wireless module is fixed on the cover plate. The clamping plate has several through slots for fixing sensors, the length of which is greater than the length of the sensor. Several through slots are connected to fixing members, which fix the sensors to the side walls of the through slots. The fixing members include several straight rods and several horizontal rods fixedly connected to the straight rods. The straight rods move in the straight slots, the horizontal rods move in the horizontal slots, and the vertical rods move in the vertical slots. A movable slot is formed on one side wall of the through slot, located at the center of the through slot and with a perimeter smaller than the through slot. A clamping piece is provided in the movable slot, which is fixedly connected to the fixing member. The clamping piece can clamp or release the sensor. This fixture allows for batch installation of sensors for batch testing, and installation and disassembly are convenient.

[0004] However, the aforementioned existing technology, which controls the straight rod to simultaneously clamp and release the sensor, has low practicality when improperly installed or disassembled separately. Utility Model Content
