With an established footprint of capability currently operational within the Brazilian Navy, there are existing cost saving measures available in order to offset startup costs, support and training overheads, as well as considerable operational advantage to be gained through Fleet interoperability and the sharing of OSI WECDIS software knowledge amongst more experienced users of the OSI product(s).

Delivering a Complete Solution for the Shipyard

OSI Maritime’s all-inclusive bridge solution incorporates our WEDCIS navigation software (ECPINS) into an IBS offering that meets all the requirements of an Integrated Navigation System (INS) as defined by IMO MSC.252(83). Key elements of OSI’s whole-system offering are:

• A complete integrated solution that includes all navigation sensors, navigation radars and associated bridge systems integrated into one bridge system providing an efficient installation and set to work  with less shipyard scheduling delays.
• OSI’s team of hardware engineers have successfully produced a range of custom hardware designs for both submarines and surface platforms.  Able to design solutions for highly specialised vessels or against demanding physical constraints as well as meeting a wide range of stringent MIL-STDs for shock, vibration, EMI and IP
• Through a balanced approach to through-life-support, our customers receive maximum benefit and lower through-life costs, to optimize availability during operations. Coupled with an inherent understanding of the needs of the naval user, our systems and products are designed with the importance of reliability, maintainability and testability at the forefront.
• To sustain our bridge solutions, OSI provides a full range of tailored Support Solutions. We have a heritage and expertise in Integrated Logistic Support (ILS) combined with an in-depth knowledge of Availability, Reliability and Maintainability (ARM) methodologies. This enables us to design project specific support solutions that maximize Availability at a manageable and measurable Whole Life Cost (WLC).

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:
• 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
