At survey of environment by distance-measuring system for mobile the essential characteristic is step-type behaviour of survey on a base plane. The essence of the phenomenon of 'interference' at repeated surveys consists that at slow enough movement МR and corresponding development distance-measuring system position of points of a repeated measuring network can not coincide with the measuring network received at the previous cycle of survey. It conducts to reduction of size of step-type behaviour a measuring network. Three-dimensional statement of research of 'interference' is considered at costing and moving МR, for one and group MR for an estimation horizontal step-type behaviour of survey.
