Fast intermittent fault detection algorithms in static test of multiple ground stations

Static test plays a key role in accuracy evaluation in range equipment test. However, the ground station equipment in static test may inevitable encounter intermittent fault, which leads to inaccurate navigation result. In this paper, two improved intermittent fault algorithms are proposed by using sorting, iteration, and recursion techniques based on multivariate statistical analysis. These algorithms not only reduce significantly the computational complexity of fault detection based on the traditional detection statistics, but also improve the navigation accuracy. It will have a wide application prospect in the future flight test and final equipment test.
