MariWeb™ AIS network software
MariWeb™ contains all of the Basic AIS Services [BAS] required by the IALA A-124 Recommendation for an AIS network to be established. MariWeb™ is ITU-R.M 1371-3 compliant and implements all of the interfaces using the published IEC61162 message format where required and possible. This ensures that MariWeb™ is able to integrate to all compliant AIS Base Stations and Electronic Chart Systems [ECS] through any number of Logical Shore Station [LSS] connections. All interfaces use open standards, where possible, with interfaces to larger back office, legacy and third party systems being accomplished by discoverable Web Services.
Central Data Server [CDS]
The MariWeb™ Central Data Server [CDS] is the central office heart of the MariWeb™system. Any number of CDS type systems of various sizes can be connected together in either a mesh, daisy chain or hierarchical topology to construct an AIS network that satisfies the network design requirements ensuring that redundancy, reliability and operational needs are fully met. This flexibility allows the CDS in various configurations to be installed at regional / sector control offices with full access to the entire network resource and all the AIS data streams, if required. The CDS also provides the interface to the many sub-systems that make the IMIS Global Limited MariWeb™ AIS networks one of the most feature rich AIS networks in the world.
Base Station Controller [BSC]
The MariWeb™ Base Station Controller [BSC] is a versatile and feature rich component that connects four (or more with a special version) AIS Base Stations to form a single AIS Physical Shore Station [PSS]. Configuration of the BSC is simple and completed using a standard Internet browser (Microsoft® Internet Explorer 6 or later, Firefox® 3 or later, Chrome®, Safari®). The MariWeb™ BSC connects to the central office environment or Electronic Chart System [ECS] using almost any Wide Area Network [WAN] infrastructure ranging from dial up links through to Very Small Aperture Terminal [VSAT] satellite system and optical fiber. The data transfer between the BSC and the central office systems is tailored to work most efficiently with the bandwidth available. Any WAN failures up to four weeks can be tolerated and the central database data set fully restored. When using the MariWeb™ Central Data Server [CDS] at the Central office, many innovative security, network management network functionality features are available.
MariWeb™ AIS Network Appliance [MANA]
The MariWeb™ AIS Network Appliance [MANA] is an AIS network constructed as an appliance. All that is required is an AIS Base Station and a PC with a standard Internet browser and then an IALA A-124 Recommendation compliant AIS network can be established quickly and easily. An OpenGIS compliant chart / map server with the capability of Google Map (Internet connection required), raster and ESRI chart display is included along with a bi-directional IEC61162 interface to an ARPA radar system. This allows a small port AIS network to be established that can become part of a far larger AIS network at some point in the future. World class 24/7/365 support is provided a broadband Internet connection.
More MariWeb™ sub-systemsThe sub-systems described below are a small subset of what is available as part of the MariWeb™ suite.
MariWeb™ Event Manager [MEM]The MariWeb™ Event Manager [MEM] is a versatile sub-system that is able to generate events by generating triggers that are based on the the AIS data obtained from vessels, the area that the vessels are in and the time of day.
When an event is triggered, pre-configured or dynamically constructed messages can be sent to other vessels, operators and users connected to the Internet alerting them to the event.
All events are stored and available for audit. Read the Port Security case study for an example of the MEM at work.
MariWeb™ Archive Server [MAS]The MariWeb™ Archive Server [MAS] can be scaled from 1TB through to more than 30TB (larger systems have been designed by IMIS Global Limited).
The MAS allows all of the AIS data collected to be available on line without sampling. This data can be used for planning, academic or forensic purposes in the secure knowledge that all data collected at that time, is available for use ensuring accurate results.
The MAS has a discoverable web service interface. Read the Information Exchange case study for an example of the MAS at work.
MariWeb™ Chart Server [MCS]The MariWeb™ Chart Server [MCS] is based on a high performance Open GIS server.
The MCS can be loaded with any WGS84 registered raster image or ESRI or S57 charts.
Should navigational quality charts be required, S63 charts can be loaded but these are subject to a a license fee.
The MCS serves chart to the MariWeb™ Human Machine Interface [HMI] which uses an standard Internet browser for the Operator Display ensuring rapid deployment and easy maintenance.
The MCS is centralised (can have multiple layers of redundancy) making chart management procedures simpler to implement and control.
Read the Offshore energy case study as an example of the MCS at work.
