Choosing between a quartz flexible accelerometer and a MEMS accelerometer depends on specific application requirements. Here are some key factors to consider:   1.   Quartz Flexible Accelerometer Advantages: 1)      High Accuracy and Stability: Quartz accelero...

The north finder is a type of compass used to find the true north direction value of a certain location. The gyroscope north finder, also known as the gyroscope compass, is an inertial measurement system that uses the principle of gyroscope to determine the projection direction of the Earth's rotati...

Fiber optic gyroscopes (FOGs) are highly accurate sensors used to measure angular velocity. They are widely used in fields such as aviation, navigation, and seismic research due to their high precision, sensitivity, and excellent stability. Its core accuracy indicators, including zero bias drift, ra...

Inertial measurement unit (IMU) is an integrated sensor kit that combines multiple accelerometers and gyroscopes to perform three-dimensional measurements of specific force and angular velocity relative to an inertial reference frame. However, in recent years, IMU has become a general term...

Electronic compass is an important navigation tool that can provide real-time heading and attitude of moving objects. Calibration of an electronic compass is a crucial step in ensuring the accuracy of its directional measurement.   1. Calibration principle of electronic compass The el...

Fiber optic gyroscope is based on Sagna effect and is widely used for measuring angular velocity in navigation and attitude control. Key indicators typically include zero bias stability, scaling factor, random walk, bandwidth, noise, temperature characteristics, and so on. By measuring these indicat...

"An in-depth analysis of the testing methods for the bias (zero bias) and scale factor of quartz flexible accelerometers is provided, including specialized techniques such as four-point rolling test and two-point test, as well as the calculation formula for temperature sensitivity. This is...

Wheel speed sensors (wheel speed sensors) are often used as auxiliary sensors in inertial navigation systems (INS) to improve navigation accuracy and suppress accumulated errors of inertial sensors. The wheel speed gauge calculates the longitudinal speed of the vehicle by measuring the wheel speed (...
