Abstract
The property of residuals and outliers was discussed by calculating GPS observation with the least square method. And then the least square method was deduced and improved. Though there was a linearization between the residual and outlier, outlier was not be able to get from residual, and some residuals made the outliers to be zero. Multi-outliers was detected effectively by transforming not only the outlier but also its numbers to minimum value problem. Outliers was constrained positive values because the ionosphere and troposphere delays were positive in code signal, and then the multiple values problem was resolved perfectly. The illustration proved that 3 outliers was able to detected by the improved algorithm.关键词
