Second GPS horizontal control survey was conducted because of the drainage construction in Sanbao Works(from Qiantang River outlet to Fengqi East Road).Two baselines were determined by Total Station Sokkia NET05X and the fitting adjustment in ranging baseline was corrected by GPS horizontal control.The accuracy of ranging line directly affects the GPS coordinates in second control network.The relevant factors of the ranging accuracy are analyzed in the paper,especially in terms of baseline,and influential principles in ranging accuracy by Total Station Sokkia NET05X are also discussed.It is pointed out that the ranging accuracy should be corrected,tested and re-operated in process and treatment.
