Abstract: Based on a common model of data processing for GPS relative positioning, this paper deduces accuracy indicators which have notions of relative positioning geometry. These indicators are easily available and estremely useful in planning GPS surveys. Then some concrete algorithms of estimating RDOP factors as well as process of verifying algorithms are introduced. At last some research results of influencing RDOP factors are given.
