Description

technical field [0001] The invention relates to temperature compensation of inertial measurement combination, in particular to an inertial measurement combination automatic temperature compensation test method and equipment, and belongs to the technical field of inertial measurement combination test. Background technique [0002] The inertial measurement combination is mainly composed of gyroscopes, accelerometers and related circuits. It is the core component of the control system. It is mainly used for the angular velocity and acceleration in the motion of the sensitive carrier, and provides attitude and position information for the system guidance control. The accuracy of the inertial measurement combination will directly affect the final guidance accuracy. [0003] In the application of inertial measurement combination, since the accuracy of gyroscope and accelerometer is easily affected by temperature, temperature control measures are usually taken to make the product w...

Problems solved by technology

However, the test time usually takes about 7 days. The time is too long, and the resources are seriously wasted. In the test, the speed table and the incubator need to be manually operated at regular intervals. The workload is heavy and error-prone, and the temperature of each parameter needs to be repeated in the compensation test. Testing is a waste of manpower and material resources. The product needs to be powered off every time the parameter is switched. The parameters of the inertial group are affected by the successive power-on of the product and the temperature change environment. The compensation accuracy is limited and the compensation efficiency is extremely low. It is difficult to promote and apply on a large scale.
