Abstract

1521301 Self-levelling arrangements MARCONI CO Ltd 2 April 1976 [16 May 1975 24 Sept 1975] 20968/75 and 39202/75 Heading G1F [Also in Division G3] A member, e.g. a radar scanner, is rotatably mounted on a craft and automatically maintained at a given attitude using a linear induction drive which acts upon a spherical track, to rotate the member and to provide inertial stabilization. As shown, induction motors 7 are fixed to a ships deck or masthead 3 and the track 6 is joined to a radar antenna 1, mounted for rotation on a ball joint or gimbal 2. In an alternative, the track is fixed and separate drive motors or quatrature motor windings are moveable. A servosystem controls each winding 7A, 7P, 7F, 7S according to signals from sensors of azimuth, rotation rate and vertical position of the antenna, and signals from the ship's vertical reference system. Figs. 5 to 7 (not shown), give details of how these signals are combined to control the windings. The voltage and frequency to each winding is controlled so as to stabilize the attitude of the antenna despite roll or pitch of the ship.
