Positionnement GPS
"Voir derrière les murs" Connecté à un lecteur de cartes
Nécessité de connecter le récepteur GPS primaire du bateau à l'AIS qui l'utilise comme source principale de position. Cependant l'AI80 équipement "tout-en-un" intégre un récepteur GPS pouvant être utilisé en secours du récepteur primaire installé sur le bateau.
Interfaçage lecteur de cartes et radar
AIS can be interfaced to electronic charts or radar provided they support the AIS interface. When interfacing AIS to radar and chart plotters, AIS target information as position, heading course and speed becomes available to the mariner and increase reliability of navigation data from other vessels.
ARPA radar interface
By activating the interface to an ARPA radar, moving targets and operator selected "fixed points" can be displayed. Other vessels are then shown in real time on the chart, color coded depending on possibility for collision.
VHF data communication
Dedicated VHF frequencies are used for AIS data communication and the range is dependant on the height of the VHF antenna. In order to avoid interference with the ship's VHF voice communication, the AIS VHF antenna must beinstalled in accordance with IMO requirements. As the SOTDMA (Self Organized Time Division Multiple Access) protocol, which utilizes timeslots for transmission and reception of data is being used, an almost unlimited number of users may operate on the system at the same time without causing interference problems.
