Abstract

914,184. Course-recording apparatus. DECCA Ltd. Dec. 20, 1960 [Dec. 28, 1959], No. 44002/59. Drawings to Specification. Class 97 (2). [Also in Group XL (c)] In an arrangement for recording the track of a craft in accordance with the computed cartesian co-ordinates and y of the craft as disclosed in Specification 914,185, x and y are computed according to the equations where h o , h 1 , h 2 are the ranges of the craft from three spaced points of known location as determined by known radio means (see Group XL (c)) and A 1 , A 2 . . . D 2 are constants depending on the positions of the points.
