SHIPBOARD RECEPTION-INDICATOR 'PIRS-1' FOR USE WITH PHASE RADIO-NAVIGATION SYSTEMS,

Abstract

The article describes a newly developed reception indicator designed for installation in the merchant fleet. This instrument makes it possible to determine a ship's position by signals from the shore stations of a phase radio-navigation system. Either the time or the frequency can be varied. The article describes three different models of the apparatus. All three types are designed to be fed from the ship's electric circuit, and operates at voltages of 220 and 127 and a frequency of 50 cycles. The system operates from a vertical marine antenna with a length of 4 meters or more, installed at an angle of 50-60 degrees to the horizontal. The instrument is designed for continuous operation for a period of 48 hours, with a rest period of not less than 2 hours, and a speed of the vessel up to 25 knots. Installation of the instrument aboard ship is scheduled to start this year. (Author)
