Error Analysis of Survey of Basic Point Trajectory of Special Equipment on Vessel

To survey the spatial position of the basic point of the special equipment on vessel and to get the trajectory of the basic point,and to make measurement error analysis, that is the important subject of data processing of some engineering.This paper puts forward the principle and the error analysis method of using 3 moving receivers to survey the basic point of the special equipment on vessel,introduces the error source component part of this method,deduces the estimate formulae of the positioning accuracy according to the principle, and explains the simulation and survey implement.
