In determining the coordinates of ground-mounted source of radio-frequency radiations with used of second-dimensional (azimuthelevation) direction finder, established on a board of airship, occurred errors, due-to an error of direction finding and navigation errors of an airship – error in measuring the indigenous coordinates and angles of space-like orientation in three-dimensional space. In a paper obtained relation, binding in the linear approaching by matrix of a covariance error estimation сartesian coordinates source of radio-frequency radiations on a horizontal place with matrix of a covariance error measure 8-dimensional vector measured parameters in the general form, also for the case of the mutual independence of the direction finder, meter’s the indigenous coordinates of the airship and meter’s the indigenous angles place-like orientation – matrix of a covariance error that 3-th meter’s.
