Abstract
Ship's attitude parameters, including pitch, roll and heading, provided in he form of synchro signals by redundant sensors, are distributed to various shipboard systems by a synchro selector binary switching tree under the control of a digital processor. The processor also generates dynamic simulations of pitch, roll and heading, which can be distributed to the shipboard systems by the switching tree.

In a shipboard attitude data system comprising multiple, redundant attitude sensor means, each sensor means providing a set of analog output signals representative of a plurality of attitude parameters, means for utilizing said output signals, and simulator means for generating a set of simulated attitude sensor output signals, in analog form, for testing purposes, a switching system comprising:
- switching means, comprising a tree of binary switches, each having two inputs and one output, for selecting any one of said sets of signals and delivering the selected set of signals to said utilizing means;
- whereby, at any given time, one and only one of said sets of signals is delivered to said utilizing means.
In a shipboard attitude data system comprising three redundant attitude sensor means, each sensor means providing analog output signals representative of a plurality of attitude parameters, and means for utilizing said output signals, a switching system comprising:
- first and second two-position switch means,
- the first switch means receiving the output signals of two of said sensor means and alternatively delivering the output signals of one or the other of said two of said sensor means to the second two-position switch means,
- and the second two-position switch means receiving the output signals of the third sensor means and the output signals delivered by said first switch means and alternatively delivering, to said utilizing means, the output signals of said third sensor means, or the output signals delivered by said first switch means,
- whereby, at any given time, the output signals of not more than one of said sensor means are delivered to said utilizing means.
In a shipboard attitude data system comprising multiple, redundant attitude sensor means, each sensor means providing analog output signals representative of a plurality of attitude parameters, means for utilizing said output signals, and simulator means for generating simulated attitude sensor output for testing purposes, a switching system comprising:
- first and second switch means,
- said first switch means receiving the output signals of at least two of said sensor means, and being switchblade to deliver the output signals of any selected one of said multiple sensor means to said second switch means,
- and the second switch means receiving the simulated attitude sensor outputs and the output signals delivered by said first switch means and alternatively delivering, to said utilizing means, the output signal of a selected one of said multiple sensor means, or the simulated attitude sensor outputs.
