Abstract

A new solid‐state, self‐compensating compass launched by Crouzet Ltd of Farnborough, Hants, provides an entirely new approach to the problem of determining magnetic heading to an accuracy meeting the requirements of tactical remotely piloted vehicles it is claimed. The compass, known as Cosac IB, continuously measures and automatically corrects for the components of the earth's magnetic field along the axes of the vehicle, allows for analogue roll and pitch data from the vertical gyro, and thereby computes the vehicle's magnetic heading. This ability to compensate continuously and automatically eliminates entirely the need for manual compensation which is crucial to the accuracy of conventional gyromagnetic compasses, and also makes automatic allowance for changes in the magnetic state of the vehicle during flight — as will occur, for example when a charge is released.
