Abstract

The invention relates to vector modulation method used in vector sensor installation error angle precision measurement. It can accurately measure vector sensor installation error angle. And it can be applied in measurement, control, navigation, location, guidance, and sensor engineering. There is no direct and high precision measuring method in the before engineering. The vector modulation method illuminates the inner feature of the vector sensor, and can obviously improve its measuring accuracy. It can be further developed to measure vector sensor installation error angle. The invention is the development of the original vector modulation method. It inputs exact modulation rate for the vector sensor and its join body, and measures sensor biasing variance to calculate sensor installation error angle. The final precision is determined by sensor precision and modulation rate input precision. The invention solves the long time technique difficulty that approximate projection method is used before; and there is no direct and high precision measuring method.

Description

Technical field [0001] The invention relates to a high-precision measurement method and principle equipment. The installation error angle of the vector sensor can be accurately measured. It is suitable for measurement, control, navigation, positioning, sensor engineering and other fields. Background technique [0002] Sensor technology is the basis of modern control and measurement technology. In the fields of high-precision measurement and control, there are high requirements for the installation error angle of the sensor. Such as inertial navigation system, the installation error is required to reach 1 arc second (1 / 3600th of a degree) in order to ensure proper navigation accuracy. When the installation error difference is less than a certain allowable value, and its value is accurately measured, it is possible to use mathematical methods to eliminate its error influence. [0003] At present, many experts and scholars are devoted to the research on the estimation accur...
