摘要：

To achieve the precision of inertial navigation equipment evaluation, accuracy evaluation system of the internal timing of the research contents include setting up unified benchmark, UTC by means of a timing device and 1 PPS second pulse, provides precise time logo for inertial navigation system. Industrial control computer platform based on virtual instrument to realize stable multi-serial port navigation data, real-time navigation data, the accuracy of the assessment for admission before a small amount of calculation of real-time navigation data outliers and cubic spline interpolation processing, processing of data after a precision evaluation of algorithm precision of inertial navigation devices. Precision of the simulation and actual experimental results prove that the new evaluation system can gather many sets of inertial navigation equipment data and greatly improve the effectiveness of the precision evaluation.
