Abstract
Abstract A navigation training simulator in which a model, representing a full scale vehicle, operates in a medium representing that in which the full scale vehicle operates, and a student remotely controls the model from a control station representing the control station of the full scale vehicle. A visual representation of navigational objects external to the model is presented to the student at the control station as they would appear to him if he were at the control station on the model. Means may be provided to permit an instructor to apply to the model forces representing wind, tide and other natural forces experienced by the full scale vehicle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A ship navigation training simulator comprising a dynamic model representative of a full scale ship and comprising a radio controlled model ship, a control station separated from said model and representative of a portion of the bridge of the full scale ship, means on the model responsive to inputs from the control station for moving and controlling the model when the model operates in an environment representative of the environment in which the full scale ship operates, means on the model for viewing and transmitting to the control station the visual appearance of objects external thereto, and means at the control station for visual display of the transmission from the model, said viewing means on the model comprising a pivotally mounted television camera responsive to the action of aN operator at the control station in scanning to either side of straight ahead relative to the model so that this view is represented at the control station, said simulator further comprising means, responsive to the swivelling movement of a chair for a student at the control station, for generating a signal which causes corresponding movement of the television camera.
Claim 2
Dependent Claim

A ship navigation training simulator comprising a dynamic model representative of a full scale ship and comprising a radio controlled model ship, a control station separated from said model and representative of a portion of the bridge of the full scale ship, means on the model responsive to inputs from the control station for moving and controlling the model when the model operates in an environment representative of the environment in which the full scale ship operates, means on the model for viewing and transmitting to the control station the visual appearance of objects external thereto, and means at the control station for visual display of the transmission from the model, said viewing means on the model comprising a pivotally mounted television camera responsive to the action of aN operator at the control station in scanning to either side of straight ahead relative to the model so that this view is represented at the control station, said simulator further comprising means, responsive to the swivelling movement of a chair for a student at the control station, for generating a signal which causes corresponding movement of the television camera.
Claim 3
Dependent Claim
26 words
A navigation training simulator as claimed in claim 1, wherein the television camera views objects exterior to the model through a prism mounted on the camera.
Claim 4
Dependent Claim
58 words
A navigation training simulator as claimed in claim 1, wherein a monitor and screen are positioned on the swivelling chair such that the angle at the eyes of a student of a given height seated in the chair formed by lines joining the edges of the screen is substantially equal to the angle of view of the camera.
Claim 5
Dependent Claim
46 words
A navigation training simulator as claimed in claim 1, wherein the model has situated thereon means to apply forces to the model so as to produce a resultant force which represents a resultant force of natural forces external to and acting on the full scale vehicle.
Claim 6
Dependent Claim
21 words
A navigation training simulator as claimed in claim 4, wherein the means for applying forces to the model comprise air propellers.
Claim 7
Dependent Claim
47 words
A navigation training simulator as claimed in claim 4, wherein two air propellers pivotal in azimuth are situated on the longitudinal centre line of the model and are spaced apart so that one is ahead and one is abaft the centre of lateral resistance of the model.
Claim 8
Dependent Claim
22 words
A navigation training simulator as claimed in claim 4, wherein the means for applying forces to the model comprise underwater force generators.
Claim 9
Dependent Claim
22 words
A navigation training simulator as claimed in claim 4, wherein the means for generating the forces on the model is remotely controlled.
Claim 10
Dependent Claim
29 words
A navigation training simulator as claimed in claim 8, wherein the means for generating the forces on the model is additionally controlled by an input from a terrestial reference.
