 For the high-latitude HOFN station, the coordinate difference fluctuation range in the N direction is large, and the value changed within -4.75 cm to 4.98 cm is considered to be normal, and the abnormal ratio is 1.51%. The phase data quality in the E direction is poor. The value changed from -2.32 cm to 2.41 cm is considered to be normal, and the abnormal ratio is 1.36%. The coordinate difference in the U direction is relatively smooth, and the coordinate difference between -0.17 cm and 0.18 cm is considered to be normal. The anomaly ratio is 1.69%.
-==5 Conclusion==
+==5. Conclusion==
 In order to analyze the GNSS data quality and its applications, we propose a new method to evaluate the phase data quality by using the EEPD. The method can efficiently remove the effects of GNSS orbit errors, atmospheric delay, multipath effect, clock error and ambiguity when evaluate the phase data quality. GNSS data of single frequency and linear combining frequency can be evaluated by analyzing the time series of coordinate differences epoch by epoch.
@@ Line 866: / Line 866: @@
 We also compared the results obtained with EEPD and the Bernese software, and found that it has good consistency with the two methods above. The results determined with these two methods are consistent, which shows that the new method is reliable to evaluate the GNSS data quality in real time.
