• Alert Management

OSI Maritime’s Integrated Navigation Systems are designed for military operations and delivers low risk, proven military capability to the warfighting navigator.

Capacités ECPINS uniquement pour MCM / ECPINS MCM Capabilities

ECPINS delivers dedicated MCM functionalities including AML, 3D, SHOL, Waterspace Management, T-ACT, Military Chart Engine, CMS Integration, and GNSS Denied:

Additional Military Layers (AML) Edition 3 coverage

Additional Military Layer
• OSI Maritime’s ECPINS delivers the full capability of Additional Military Layers (AML) as defined in STANAG 7170 addressing Ed 1, 2 & 3.
• Military rich Hydrographic information beyond that necessary solely for maritime navigation as defined by SOLAS.
• AMLs are intended enable interoperability supporting the principle of “operating off the same map”.AMLs provide the military maritime user with digital vector and gridded data to support situational awareness across the full range of warfare scenarios at every operating level from strategic planning to tactical operation.

AMLs provide the military maritime user with digital vector and gridded data to support situational awareness across the full range of warfare scenarios at every operating level from strategic planning to tactical operation.

Integration in CMS (Combat Management System)

Combat Management System
OSI Maritime has extensive experience in integrating with CMS on both submarines and surface ships, including:

• Naval Group SETIS
• LM Canada CMS330
• Raytheon AN/BYG-1

Our Navigation Tactical Data Distribution Unit (NavTac DDU) provides the interface between the CMS and the IBS and is a single data source from which all other systems can exchange information with the ship’s sensors.

Designed to interface with modern combat management systems, OSI’s NavTac DDU delivers a lowest risk, proven, technically compliant solution to satisfy the requirements of an IMO 252(82) data distribution sub-system for any Class of Surface Combatants or Submarine.

Warship AIS (W-AIS)

• Conforms to NATO STANAG 4668 (W-AIS) using full MIL STD-2525 tactical symbology.
• Operators can change the contact’s name, symbol, or affiliation, as well as set an alarm when the contact is within or outside a specified range, and have the display show slower contacts as smaller symbols.
• Contacts of Interest – W-AIS provides tools to search, sort, filter, query, set alerts and export ARPA, AIS or CMS tracks.
• Deception and Spoofing – W-AIS provides the ability (subject to user-permissions and authentication) to adjust the information transmitted by ownship and to transmit simulated AIS contacts

Incorporating the same WECDIS look & feel, OSI Maritime’s W-AIS delivers a compiled Recognised Maritime Picture (RMP) and has multi-featured Operator Settings
