SHIPBOARD RECEIVER - INDICATOR FOR THE PHASE-COMPARISON RADIO-NAVIGATIONAL SYSTEMS 'PIRS-LI,'

Abstract

The report contains the development of a shipboard receiver-indicator group, 'PIRS-I' for installation aboard ships of the merchant fleet and the fishing fleet. The device makes it possible to obtain a fix of the ship's position by using the signals from shore stations of the phase-comparison type of radio-navigational systems (RNS) using either the time (Mode R) or frequency (Mode D) mode selections. The systems require the use of special charts, or plots, that have an overpoint of hyperbolic iso-lines for those sea areas that lie within the established useful range of the systems. (Author)
