GPS Elevation Abnormal Fitting Based on Matlab
2013
GPS has its deficiency in the elevation pointing accuracy aspect because the geoid is an irregular curved surface and it is unable to simulate with an accurate curved surface,which enables GPS only to provide for us the accuracy of the geoid height rather than the normal height in our project needs.So it has seriously affected the three dimensional localization application development of GPS and made the superiority of providing the three dimensional coordinates not able to obtain the full display.By collecting and analyzing the domestic and international study methods and application techniques of GPS leveling in recent years and based on these research results,complex terrain,geoid characteristics,and the case study,the paper studies GPS elevation abnormal fitting in large areas.
