Aerospace Instrument-Making Annotation << Back Technical system for angular coordinate measurement V.Ya. Raspopov, D.M. Malyutin, Yu.V. Ivanov, R.V. Alaluev The description of the small-size technical system for angular coordinate measurement of the product such as “Igla” is adduced. The system provides issue of values of the directional (azimuthal) angle and of the angle of elevation or otherwise the error angle between the direction of the principal axis of the product such as “Igla” with a horizontal plane.
