GPS-leveling using RTK method

摘要

Diploma work focuses on the GPS height determination, using the real-time kinematics surveying method. The work presents an overview of the automated procedure of calculating orthometric heights on the terrain in real-time with support of the mobile computer, the procedure of calculating local geoid surface, all the equations in chronological order from GPS derived WGS84 coordinates to orthometric heights, applying the law of propagation of variances and covariances. Analysis examines obtained height accuracy, compares calculated and given heights, questions the value of the described GPS RTK height-surveying method.
