Abstract: In this paper, a new algorithm is employed in global positioning system (GPS) rapid positioning using several-epoch single-frequency phase data. First, we define the double-

Abstract: As a well-known numerical approximation method, the least squares fitting method is widely applied in surveying engineering. The most important and difficult problem in this method is to determine the type of base function ...

Abstract: In order to combat the influences of both outlier and multicollinearity on geodetic adjustments, a new robust-biased estimation method is proposed by combining outlier identification with biased estimation. The estimation ...
