On the basis of an error theory of measurings the estimate of possibility of decrease MSD of errors of definition of coordinates of the flying machine for embodying of an expedient of formation of the virtual basic channel is spent. Expressions for calculation MSD of errors of definition of coordinates of the flying machine on the basis of the following mechanism and distance finder data, and also two conjugate following mechanisms are gained.
It is shown that at use of the data of a following mechanism and a distance finder for maintenance MSD errors of definition of coor-dinates of the flying machine no more than 3 … 5 m are necessary to register corners of vising of a land reference point with MSD errors no more than 0,06 … 0,1 hailstones at ranges to 3 km and no more than 0,01 … 0,05 hailstones at ranges 5 … 9 km that can be quite realised the up-to-date gyroscopes and optical following mechanisms.
At use of two conjugate following mechanisms for achievement of split-hair accuracy of definition of coordinates of the flying machine (MSD it is equal 3 … 5) it is necessary to spot corners of vising of land reference points with MSD errors no more than 0,006 … 0,05 hailstones at ranges to 3 km that 10 times less, than at use of the data of a following mechanism and a distance finder. Therefore it is expedient to apply the given expedient of definition of co-ordinates when requirements to accuracy less rigid and MSD errors makes 10 … 20 metres. Then the limiting range to object it is possible to increment about 5 km and to spot corners of vising with MSD errors no more than 0,01 hailstones.
