摘要

A two-step fault detection theory, which consists of residual Chi-square Test and velocity detection based on robust differentiation via sliding mode, is presented. Simulation indicated that with this method excellent detection results were achieved, when step fault or slowly growing slope fault occurs within GPS signal.
