The available options for system and user configuration enable you to define a range of parameters, tailoring your AIS Service Management setup to suit your preferences and needs.
Once your system is setup, the Data Coverage, Data Transmission and Data Link Monitoring features allow you to monitor your AIS services on all important parameters. Know the amount of data available in a given area and continuously monitor the message stream within your AIS system.
OceanIntel’s system configuration options allow you to configure all hardware and software components in your AIS system network. That enables you to configure any AIS stations, services, and users while providing an audit log of system activities. Furthermore, it is possible to: Set the MSSI of a PSS, configure slot assignments for a base station, as well as which servers the individual software components must run.
On a more detailed level, you can configure your data source monitoring settings, incl. the maximum invalid message rate, inactivity timeout, no data timeout, future online message rate, and monitoring period.
A diagram shows you the layout of your system, including computers, routers, and network lines. Further, you get a status overview of the entire system, with the ability to display detailed information for each item as required.
In OceanIntel’s AIS Service Management service, you have the capability to manage user preferences. You can add and delete users as well as modify user settings, user rights and user filters. Additionally, it is possible to combine users in groups, making it easier to administer large numbers of users. It is also possible to create filter groups, so that many users can share the same filter. The users are stored in Active Directory and in the AIS configuration framework. This application can be run on any of the servers in the system.
The user configuration options also enable you to customize your dashboards which you are using as part of your AIS Service Management service by OceanIntel. The available dashboards show: AIS message type, message count, message latency and data rates for all sensors.

This feature monitors the coverage of a specific area at a given time. This information includes the amount of data available for the given area, the duration with a configurable resolution as a percentage of the normal data amount for the given area, as well as gaps in data and bad coverage for the area.
The principle behind is that the ships passing in the area should send out messages with a certain frequency depending on their current speed and turning profile. Based on the knowledge of how often ships should report their position, the report is calculated on the actual number of received messages compared to the expected number of messages. Values > 80% is considered good coverage.
The Transmission Monitor continuously monitors the message stream, and can perform two types of checks:
During the transmission verification, it is checked when a message is received by the system. For this, the transmission monitor will attempt to match it to a message sent by the system. If a match is found (i.e., the transmitted message has been received by another transponder than the one transmitting it), the transmitted message is marked as successfully transmitted. This information is available in the Audit Log.
During the spoofing detection, it is monitored whether the system receives a message with a source MMSI indicating that it was sent by a transceiver which is part of the system, and the message was not sent by the system. If that is the case, the message is marked as a spoofed message. This information is available in the Audit Log.
Configure and monitor VDL load: When a base station is selected in OceanIntel’s AIS Service Monitoring, you can see VDL Load, Allocations and Reservations where available.
VDL load information is derived from the NMEA FSR sentence (this sentence must be enabled on the base station for VDL Load information to be available).
Slot reservation information is derived from the Data Link Management (DLM) messages received from the base station.
Slot allocation information is sent by the base station, based on its configuration. Note that for this information to be up to date, it is necessary enable polling of slot allocations from the base station.
