Abstract :
The paper presents a redundant strap-down attitude system which uses three miniaturized gyro sensors linear clusters in the inertial detection unit. The data from the sensors in each of the three clusters are fused by using a statistical method based on the minimum variance method, in order to improve the useful angular speed signal measured by the detection unit.
