This basically means that the existing set of antennas, cabling, and frequency allocation plans didn´t need to be changed at all to see it implemented. Self-test the AIS SART every 6 months, more frequent self-testing is not recommended as it can cause unnecessary draining of the battery. The AIS SART contains … 2100 MHz and 900 MHz to produce a maximum frequency bandwidth of 120 MHz (60 MHz x 2). VHF Marine Radio Service Frequency Table.

AIS 2 is Cleared First • Before 2004, AIS 2 was a federal land mobile all-government-agency frequency with dozens of users • Land mobile narrowband mandate enabled this rapid reallocation • NTIA & its Interdepartment Radio Advisory Committee directed all non-AIS uses be phased out by the end of: – 2004: coastal – 2005: 200 nm of navigable waterways – 2006: All others From January 1st 2010, after several years of product development and standardization work through international organizations, the AIS-SART will be adopted into the GMDSS regulations as an alternative to the Radar-SART. The unique and innovative feature of the AIS-SART is the combination of its physical size and technical capability. The housing of the AIS-SART is identical to JotronÂ´s Ais Sart Manufacturers, Factory, Suppliers From China, Our company has already set up a professional, creative and responsible team to develop clients with the multi-win principle. AIS SART ?

The maximum communication range depends on both heights of transmitting antenna and receiving antenna. A=2.5(√H+√h) （nm） H and h refer to the heights in meter of antennas above sea. As required, AIS-SART should cover at least 5nm on the condition that transmitting AIS SART being at the top of a wave, so enhancing the probability of reception.

These devices may be either a radar-SART, or a GPS -based AIS-SART ( automatic identification system SART). A standard SART 9 GHz radar transponder, produced by Jotron, on board a Norwegian ferry. Because of the frequency used by the SART, (9.2 to 9.5 GHz) known as SHF or Super High Frequency, the Search and Rescue Transponder is considered to be a line of sight device much like the VHF radio. The antennas must be able to “see” each other to operate effectively. The Automatic Identification System (AIS) is an automated tracking system used on ships and by Vessel Traffic Services (VTS) for identifying and locating vessels by electronically exchanging data with other nearby ships and VTS stations. AIS transponders use two different frequencies, VHF maritime channels 87B (161.975 MHz) and 88B (162.025 MHz). An AIS SART signal is shown on any AIS receiver as a special MMSI-like coded symbol.
