At present, quartz flexible accelerometer is widely used in inertial navigation system, and is one of the important measurement sensitive components in the precision guidance of inertial navigation system. Its working principle is to convert the sensitive acceleration of the carrier into the corresponding electrical value and transmit it to the navigation control computer, and then obtain the displacement value of various attitude of the carrier after integral calculation. The stability of quartz flexible accelerometer also directly affects the stability of inertial navigation system. By analyzing the output model of the quartz flexible accelerometer, it is found that the main factors affecting the stability of the quartz flexible accelerometer are the index of offset value and scale factor.
The stability of the quartz flexible accelerometer is the main factor of the system (or device) with the quartz flexible accelerometer as the main sensor. If the stability of the quartz flexible accelerometer is good, its calibration period is longer, and the calibration period of the system (or device) can be correspondingly longer. In the application process of quartz flexible accelerometer, the main factors affecting the stability of the quartz flexible accelerometer are the stability of the offset value and the scale factor. In view of these two important factors, the quartz accelerometer products introduced by Ericco have good bias and scale factor stability. Take
ER-QA-03A as an example. its bias repeatability is 10-50μg,scale factor repeatability is 15-50 PPM and class II non-linearity repeatability is. Its bias repeatability is 10-50μg,scale factor repeatability is 15-50 PPM and class II non-linearity repeatability is 10 to 30 mu g/g2.
