重力梯度测量对加速度计温度系数的需求分析
Requirement analysis of accelerometer temperature coefficient in gradiometer measurement
摘要
Abstract
The accelerometer bias and the scale factor are sensitively influenced by temperature so that the precision of gradiometer measurement system is affected.The measurement equation is derived according to the principle of gravity gradiometer including the temperature coefficient of accelerometer bias and the scale factor.The values' range of scale factor coefficient of temperature is presented by assuming some parameters and analyzing the relation equation.Taking some accelerometers for example, the choice of two positive temperature coefficients and two negative temperature coefficients makes the total temperature coefficient fall from 15.255 ppm/℃ to 1.075 ppm/℃ and meets the demand of the temperature coefficient.关键词
