Modeling and Simulation

Future Vision




Simulators are powerful tools, able to mock up equipment, environments and complex systems with fidelity.

Using simulators, it is possible to replicate, controlledly, situations which would imply great costs and/or risks in the real world.

Due to these features, simulators are ideal tools to leverage the preparedness and training of the personnel, with reduction of costs, generating data to support operations' planning and even to optmize processes or create new procedures.

The Modeling and Simulation Division of CASNAV (Center of Analysis of Naval Systems) is endowed with professionals able to work on all phases of simulators' life cycle, since requirements gathering up to the development and aplication of simulators.

The following are expertises of CASNAV's M&S Division:

  • Development of Virtual Simulators for training;
  • Development of Constructive Simulators for training, analysis or wargaming; and
  • To aggregate, increment and disseminate the body of knowledge in the area of Modeling and Simulation, Virtual Reality, Augmented Reality and Computer Vision.




Bridge Simulator (SIMPASS)

The Bridge Simulator is a project started in 2011 by the CASNAV's M&S Division, which initial aim was to develop a Merchant Ship Simulator for the Merchant Marine Officers Training School (EFOMM). However, several by-products were derived from that initial simulator, making it possible to supply training needs of several other Military Organizations of the Brazilian Navy.

The SimPass and its by-products and adaptations are being used since 2013 effectivelly for training and instruction of tasks related to navigation and shiphandling, either for military and civilian vessels. In its immersive virtual environment it is possible to execute the following tasks:

  • Visual navigation in several environmental conditions, varying the state of current, waves, wind, visibility, hour of the day, etc.;
  • Radar Navigation (ARPA, Parallel Indexing, Radar Distances, etc.);
  • Electronic Navigation using ECDIS;
  • Track and control of surface contacts;
  • Tactical Maneuvers (screens and underway replenishment);
  • VHF Radio and visual (searchlight and flags) communications;
  • Mooring maneuvers;
  • Anchoring;
  • Man overboard;
  • SAR (SART, smoke signals, flares);
  • Tugship maneuvers;
  • Familiarization with the influence of environmental factors on ship's dynamics (bottom effects, squat, canal and banks, current, wind and passing-ships); and
  • Bridge management under extreme conditions of equipment failures and emergencies.

SimPass By-products

Since CASNAV developed and fully owns the intellectual property of SimPass, it was possible to adapt and modify it to suit other needs of the Brazilian Navy, producing the following by-products:

Merchant Ship Bridge Simulator (SimCIAGA)

The Merchant Ship Bridge Simulator was officially inaugurated in the Instruction Center Admiral Graça Aranha (CIAGA) in 2018. It is a virtual simulator, chiefly didatic, of the type Full Mission Ship Simulator (FMSS), developed in accordance with the STCW (International Convention on Standards of Training, Certification and Watchkeeping) requirements.

A FMSS simulator is a full-scale mock-up of a ship bridge, where thw visualization of the external environment is done through the bridge's windows using virtual reality, also provided with the mock-up of the main consoles and equipment necessary for shiphandling.

The simulator is divided in modules or subsystems. The inclusion of some real equipment improves the simulator capacity to reach the learning objectives and familiarize the trainees with the kind of interface that they will find in real ships.
