Gps In The Measurement Of Highway Projects

According to application of GPS in highway project, the thesis investigates theories and means of data process of high precision GPS by the numbers and roundly. It introduces GPS's compose and characteristic of work, and application status in h ighway. B ased o f GPS p osition principle, the thesis analyses main errors of position and gives process means and mathematical model. It studies high precision static position theory for the c arrier measurement data. The paperstudies GPS data process course and introduces the GPS data process soft GAMIT. Aim at highway project measurement, the thesis studies the measurement means of based Continuum Operation Base Station and gives a great deal test result.
