Automatic Transmitter Identification System (ATIS)
ATIS systems are identification tags used by inland commercial waterway traffic on rivers in Europe. The FSKFrequency-Shift Keying burst is appended at the end of every voice transmission by the vessel operator. It lasts for 285 milliseconds after the PTTPush To TalkPress to TransmitMinistries of Postal, Telephone, and Telegraph Service (Soviet Agency) button has been released.
ATIS is in use among European countries that are part of the Regional Arrangement Concerning the Radiotelephone Service on Inland Waterways or RAINWAT. The system is in particular use along the River Rhine, as well as the Danube and Rhone rivers.
The ATIS transmission contains a unique identifying number based on a ship's MMSI number. The primary difference between MMSI and ATIS numbers are that ATIS numbers add a 9 at the front, so that ATIS identification numbers are 10 digits long. e.g. MMSI: 207072225 ; ATIS: 9207072225.
The ATIS transmission burst has a baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. rate of 1200 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second., and an 800 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). shift. In addition, FECForward Error Correction is used in the transmission.
