Abstract: 1490588 Radio navigation system SPERRY RAND CORP 22 May 1975 [24 June 1974] 22078/75 Heading H4D Passage of vessels through a confined navigation channel, via a dangerous way point, e.g. bend F, Fig. 1, is monitored, possibly together with passage of the vessels along lanes joining other way points A-E, by means of a fixed radar installation 56 supplying position and speed information on the vessels to a PPI display 61, Fig. 8, and also to a computer 55 controlling the production of (predicted distance along channel versus time from present) lines 133, 134, 135, 136 on a C.R.T. display 45, Fig. 3, the display indicating the radar determined "now" positions 33, 34 of two vessels at 1 N mile from way point E and 1 N mile from way point G respectively and the computer generating, from their respective determined speeds of 15 and 10 knots, their predicted passage, including their passing-by position and time, i.e. 6À5 N miles from E at 22 minutes from "now". If the predicted passage is too near the dangerous way point F (line 19b) (as possibly defined by a parallelogram centred on the cross-over, intercepting the line 19b) an alarm is actuated and the operator then investigates the result of speed alterations of the vessel(s) using keyboard 65. A line 136 may be generated by the computer using intended time and speed data of a vessel as communicated to the operator and fed into the computer using keyboard 65. The numbers 33-36 round the edge of the display and identifying the lines, together with the speed numbers 15, 10, 5, 15 alongside the lines are produced by generator 58. Channel schematic 16 may be on a card or traced on the C.R.T. using the computer. The passage of vessels along branching channels, e.g. B to E and C to E can also be monitored if the channels are assigned colours, Fig. 2, and a colour C.R.T is used for the display, Fig. 6. As the "now" time will be continuously advancing, the lines at each frame have to be moved up by relative amounts depending on the speed of the vessel. (For Figures see next page.)
