Single-axis Accelerometer-based Range Correction Method for the Rocket-assisted Projectile and Precision Analysis

This paper proposes a single-axis accelerometer-based range correction method for rocket-assisted projectile, which is applicable to the low-cost autonomous correction for the range-extended projectile with the range being mainly influenced by the deviation of the rocket thrust force. Based on the proposal of the basic principle of the method, it performs analysis and calculation on various elements that influence the precision of the system. The results show that the relative circular error probable of the range, which cannot be eliminated by the correction system, is 0.28%, the relative circular error probable of the range, which is caused by the sensor system, shall be less than 0.18%, and the null-drift error of the sensor is required to be at least less than 0.04% of the full range.
