The evaluation device of the ground-based satellite navigation reinforcing system is a B included in the VHF data broadcast signal of a residual error calculating unit, the ground-based satellite navigation reinforcement system for calculating the residual error satellite altitude for each of the performance rating of the ground-based satellite navigation reinforcement system -value using the data using a first standard deviation calculation unit, GPS L1 and L2 carrier signal of the carrier signal to the satellite altitude calculated by the respective B-value standard deviation calculation of CMC (Code-Minus-carrier) value, a second standard deviation calculating section, and the satellite altitude exceptional residual error and the B-value standard deviation, and the ground-based satellite navigation comparing the CMC standard deviation for calculating a satellite elevation angle by CMC standard deviation using the CMC value reinforcement comprises system performance assessment to determine whether it satisfies the required performance parts.
