Design and Realization of Strapdown Inertial Navigation High-Precision Accelerometer Signal Acquisition Unit*
摘要
Abstract
The basic principle of the strapdown inertial navigation accelerometer signal acquisition unit is proposed firstly. The acquisition unit in many functional characteristics, such as the bias stability and the scale factor stability is analysed. The main target of the acquisition unit is presented, then the performance of essential components which conclude sampling resistance, operational amplifier, reference voltage, AD converter, and their influences on the precision of acquisition unit are studied on. The high accuracy accelerometer acquisition unit should be realized on the design of circuit and the selection of essential component. After the design is completed, the test results of the noise of the acquisition unit, temperature and time stability show that the designed acquisition unit meets the performance requirements of SINS.关键词
