Dual frequency ionosphere-free observations are usually applied to evaluate the satellite based augmentation system (SBAS) user differential range error (UDRE) integrity with the drawback of noise amplification. Instead, a range domain integrity method is proposed to assess the combined effect of SBAS ionospheric corrections, ephemeris and clock corrections. 240 days data of from 100 international global navigation satellite system（GNSS）service (IGS) stations are employed to evaluate the service performance of wide area augmentation system (WAAS) and European geostationary navigation overlay service (EGNOS). Results show that: The grid ionospheric vertical error (GIVE) integrity of WAAS and EGNOS achieves 99.96% and 99.91% respectively and the accuracy of ionospheric correction is 0.56 m. The range domain integrity of WAAS and EGNOS is better than 99.999% and the GPS user range error (URE) after applying the corrections achieves 0.34 m. For WAAS, the 95% horizontal and vertical positioning error is 1.19 m and 1.72 m, whereas for EGNOS, it is 1.18 m and 1.68 m. During the test, there were no integrity risk events. It is confirmed that it is feasible to evaluate the SBAS performance—particularly the integrity—using a geodetic receiver. The average availability of positioning accuracy for WAAS during approach with vertical guidance I (APV-I) is 99.9%, while for approach with vertical guidance II (APV-II), it ranges from 80% to 95% within the center of the service area. The average availability of positioning accuracy for APV-I of EGNOS is 99.9%, and for APV-II, it is 94.2%, indicating a higher level of availability, largely because most of the EGNOS assessment stations are located in the center of the service area. The SBAS availability noticeably decreases at the edge of the service area.
