The Posture Measuring And Calculation In Particular Condition

The request of precision about the ammunition is being more and more enhanced along with the high-tech war, installing the simple control devices for the conventional ammunition becomes an effective way to increase precision of the conventional ammunition. The Strap-down Inertial Navigation System is a kind of advanced inertial navigation technology, it's advantages makes it feasible to be the realization of the conventional ammunition simple control, to actualize the simple control on conventional ammunition is the hot spot of the domain of ammunition. How to make it real that combine the existing technology and the theory to realize simple control function on the conventional ammunition becomes the question which the ammunition expert needs to face.This paper take the alteration which makes uncontrolled rocket's to be the simple-controlled ammunition as the study subject, carry on an investigation into rocket's posture algorithm on high-Dynamic conditions; Scheme out a method of low cost posture measure strap-down system which bases on the DSP chipThe works of the paper are:â‘ Has conceived a strap-down posture measuring system method based on the MEMS according to the conditions of rocket application, selected the hardware according as the performance design.â‘¡Find the best posture algorithm through mathematical simulation research on the two-sample,three-sample,four-sample rotation vector and quaternion method, and find the best frequency of sampling after analysis by synthesis.â‘¢design and debug the software of the posture measuring system, which carry on about the corresponding DSP chip.The research work of this paper will be the basic of practical project. The process of posture solution algorithm design acts practical significance.
