About i-AtoN
The purpose of the i-AtoN Management system is to provide the authority or agency operating an i-VMS system with tools for managing small or large AtoN systems, by:

• Providing the users with an AtoN database/register where key information of all AtoN’s are stored
• Providing the users of the AtoN system with a chart and/or Web based view of the AtoN status
• Integrating the AtoN status information as part of the VTS RMP (Recognized Maritime Picture).

The i-AtoN system is capable of collecting real-time monitoring information using any of the existing compliant monitoring interfaces such as:

• ZeniLite, Akari Binary Messages and/or AIS Message 21 as defined by IALA
• OPC (Open Process Control)
• GSM/GPRS SMS
• Database
• ORBCOM/Inmarsat (E-Mail)
• Integration and Engineering with other SCADA systems

The i-AtoN system can be customized to collect AtoN monitoring and measurement data from almost any existing legacy AtoN management system.

Operational Objectives
The operational objective is to provide vessels in the VTS or AtoN responsibility area with tactical up-to-date digital status information of the AtoN status, using AIS 21 virtual and pseudo messages.
The i-AtoN is part of the Navielektro Watch Framework and may be deployed either as a stand-alone application or as part of a VTS or Coastal Surveillance System. The i-AtoN system may be built using any of the existing modules to fit specific customer needs. The minimum deployment may e.g. consist of only a manual AtoN register with an integrated web service. The i-AtoN system is comprised of the following basic modules:

• AtoN Basic Data Collection Services
• AtoN Data Logging Service
• AtoN Web Service
• AtoN JMAP ECDIS presentation module
• AtoN AIS Broadcast module
• The AtoN Watch System contains the following optional modules:
• AtoN Special Engineered Data Collection Services
• AtoN Work Order and Failure Reporting
• AtoN Inventory Management System
• AtoN Status Reporter
• AtoN Deployment System
• IT Infrastructure Management
• Integrated Lightweight AIS Network Support

AtoN Watch Web Service
The Aids to Navigation Web Service is the basic component of the i-AtoN system allowing personnel to easily view the current status of the AtoNs.
