| Abstract: | Systematic errors in distance observation are harmful to adjustment work.When there are obvious systematic errors in distance observation of a connecting traverse,a method of adjustment by condition equations using distance coefficient can reduce its influence.It is proved to be of high accuracy,efficiency and economy. |
