Error compensation method of mine-used drilling trajectory measurement system

Abstract

The paper introduced structure and measuring principle of drilling trajectory measurement system, and elaborated error sources and compensation method in details from three aspects including sensor itself, environmental conditions and sensor installation. The simulation of the physical scene of horizontal directional drilling, and analysis of attitude angle before and after the error compensation show that making appropriate error compensation for different error source can improve the accuracy of attitude angle measurement.
