Application and Analysis of GPS Trigonometric Leveling Method
The GPS trigonometric leveling method is a relatively special method for measuring elevation. This article provides a general overview and summary of existing measurement methods and concepts,briefly summarizes the suitable conditions for this method,and provides a simple analysis and discussion of its principle,background,and practical significance. It provides evidence using data ob-tained from practice. The principle introduction covers the method of GPS trigonometric leveling;deriving the measurement height difference of GPS trigonometric elevation through calculation formulas;requirements and constraints related to accuracy and error;in-volving the elevation system applied. The above content has been systematically elaborated and explained. It ultimately proves .0that the GPS trigonometric leveling method can meet the accuracy requirements of fourth class leveling and is suitable for completing eleva-tion measurement tasks under specific geographical conditions.
