1. Thyssen ln and lk are accelerometer sensors in inertial navigation systems. 2. Thyssen ln and lk use different working principles. Thyssen ln is an oscillation circuit based on a quartz crystal resonator, and the acceleration can be calculated by measuring the oscillation frequency.
lk uses micromechanical system (MEMS) technology to convert acceleration into electrical output. 3. The accelerometer sensor in the inertial navigation system plays an important role, which can provide high-precision attitude measurement in the fields of aerospace, missiles, drones, etc., so that the airborne equipment can accurately perceive the change of motion state and position information.
