Abstract :
The functioning of an inertial navigation system (MS) is based on the modeling of the Schuler pendulum (1923) by a “gyro-accelerometer” (G-A) system. For such a system, a simplified structure of one channel is shown. This structure ensures the invariance of the modeled vertical with respect to the motion of the accelerometer base. If, however, the initial errors are unknown, the system will oscillate about the true local vertical; such oscillations are described by a differential equation
