Radio Positioning

Equipment for ships to use radio technology. At present, the general purpose of the measuring instrument, Kang Suoer and other azimuth systems and Roland, Taiwan Card, Omega, Meridian Instrument navigation and other hyperbolic systems. They have advantages and disadvantages, can be used to complement each other, but not mutually replaceable. The ideal positioning system is yet to be developed, which requires global, 24-hour, self-contained, passive, fully reliable and high-precision. Omega and Meridian Navigation systems have been known as the two major achievements of navigational technology since in the 1960 of the 20th century, but they have only some of these conditions. The new United States satellite navigation system, which will be formally put into use in the late 80, is called the GPS Global Positioning system. It can be positioned continuously, the accuracy is higher than the meridian navigation system, and it is a new technical achievement to the ideal positioning system.


In addition, nautical instruments include meteorological and hydrological observations, such as barometric gauges, wet and dry thermometers, anemometer, etc.
