An outline of the GPS system, position of the main features and the status of highway engineering; discusses the GPS-RTK cross-section measurement in the application of highway engineering advantages; from the basic principle of GPS positioning, detailed analysis of the GPS- RTK surveying outside the process: systematic study of latitude in the South CASS with software use. Papers with CASS and latitude to the south of software use, comprehensive study of the road GPS RTK operation mode of the characteristics of measurement and the application of GPS RTK technology road measurements (including road surface, profile, cross section) the entire process, and highlights South bining with the latitude to the process of drawing cross-section and earthwork calculations. GPS RTK paper discusses bination with conventional water level to solve specific engineering problems, CASS and the latitude of the South proposed bine the concept drawing, saving time.
