The fax receiver is designed for use on ships in order to obtain weather maps. The equipment of this device includes an antenna and a receiver unit, which, in turn, can be equipped with a display for displaying information.
The principle of facsimile transmission is as follows: by splitting the transmitted image into elementary components and sequentially converting the degree of reflection of the light beam detected by the photocell into electrical signals.
FAX weather is divided into two types: paperless (digital) and with an integrated printer that prints meteocards. In order for the image to be of high quality, precise and precise, the receivers are equipped with a choice of the most suitable signal frequency.
A weather fax is not a mandatory device for installation on a ship. Weather maps can also be obtained via satellite Internet or special applications on the computer when connected to a HF antenna.
Weather maps are transmitted by special stations located in different regions of the Earth. The transmission sessions are performed at the same time at different frequencies. This allows you to increase the reliability of the system. At present, updated weather maps are transmitted every 6 hours.
