【Abstract】 :This paper has outlined the construction and observation of Dopper network in Ch-ina and the mathematical model of semi-short arc adjustment with three parameters andshort arc adjustment with six parameters.By test computation the main parameters, a set of optimal parameters has been cho-sen and used in formal adjustment computation, which is helpful to improve the conve-rgence accuracy, speed up the computation velocity and raise the adjustment quality.The adjustment and comparison have been by two kinds of programs, one is a pr-ogram of three parameters, the other of six parameters. In order to chek the adjustm-ent results we have compared those for common points and common distance in diffe-rent zones. Also made has been comarison with over all adjustment result of the astrog-eodetic network and with superorder traverse data as well. After these comparison ithas been proved that the relative error of the results is less than 1:500000 on average.更多还原
