JVNAN-1000 AIS AtoN Station (TYPE I)

 

1, Full compact design.

2, No outside GPS or VHF antenna.

3, Very low power consumption.

 

Used for light monitoring from the authorities. In addition, its transmission can alsobe received by shipborne AIS to learn the position status of the AtoN.

 

As Type I defined by IALA, it is specially designed to be used for buoys, which carries limited batteries to supply any additional electronic equipment. It can also be used on langby, light vessel and big rigs at sea.

 

A standalone unit with built-in GPS antenna and VHF antenna. water-tight.

 

Type I AIS is transmit-only, without any receiver process, which operates only at slots preserved by AIS base stations.Such AlS can only installed within the coverage of base stations.

Conform to the international standards suchas IALA A-126, IEC 62320-2, ITU-R M.1371-5 and IEC60945.

 

Astronomical Instruments

 

It is used to observe the height of celestial bodies. According to the equator and horizontal coordinates of the celestial bodies, the astronomical triangle is calculated to obtain the ship position. In 1431, when the Chinese navigator Zheng He was on a mission to the West, he used the "starboard" for positioning and navigation. Around 1570, right anglers and quadrants were used for positioning and navigation in Europe.

 

By the 18th century, sextants and astronomical clocks appeared. In 1837, the American captain T. Sumner discovered the astronomical ship position line and the method of calculating the latitude and longitude; in 1875, the French naval officer M. Saint Iller perfected the height difference method, which has been used today. These instruments can only be used to observe celestial bodies on a sunny day during the day or when the water antenna can be seen.

 

After the gyro stabilized platform appeared, the day and night celestial tracker was made. Since then, there has been a radio sextant that can navigate in gloomy weather, but the error is large.
