Simulation Systems

Since 1995, OSM has been successfully implementing simulation systems in the maritime and defence environments using rigorous software engineering practices and establishing a suite of components which can deployed in a flexible manner to directly match our Client needs.

OSM can create part task, task, team and full mission training systems or system test facilities.

Simulation Products and Services Covering:

Scenario Control with Multigaming Capability
OSM simulation products provide a flexible framework for simulation and training, especially within the maritime and defence markets. These products enable operations analysts to create tactical scenarios within a controllable synthetic environment populated with user-defined dynamic entities such as submarines, warships and merchant ships. Individual vehicles may be linked to external systems that provide real time control for manned situations. Facilities are provided to use these links to allow other instances of the framework to communicate together to create a multi-gaming environment such as, fleet wide operations and one-on-one maritime engagements between entities in the simulation environment. The framework includes a scripting facility that can be used to generate or repeat real-time behaviour attached to entities within a scenario. An operations analyst can issue diverging commands from a previously recorded scenario script to refine or create a new scenario providing a Tactical Development capability.

Vehicle Modelling
OSM is a provider of computer-based simulation, which captures the functionalities of multiple interacting entities from platforms to sensors. We understand the fidelity to which these entities should be modelled depends on the requirement of the simulation environment. As such, our simulations are represented by multiple components with dynamic behaviours and interaction with the environment defined for the scenario. These components include the active and passive sensors, weapon systems, platform dynamics, environmental models and visual models.

Weapon Modelling
OSM can provide clients with a Generic Weapon Simulator to complete the range of vehicles modelled within the Scenario Control system. The simulator can be used to model any weapon type as the weapon behaviour is scripted using XML providing clients with the tools to create their own models in-house to generate specific high fidelity weapon behaviour models using sensitive and classified detailed weapon data thus allowing Clients to compartmentalise information release to third parties to maintain weapon capability security. Links are provided with a well defined API which allows external Weapon Systems to communicate with the model to control launch, presetting and post-launch control. Generic weapon control GUIs are available from OSM.

Acoustic Modelling
Acoustic phenomena are modelled as discrete sources (any aggregation of tonals, harmonics, broadband and modulated broadband) defined for every vehicle modelled in the scenario. Various levels of acoustic propagation models can be utilised dependent on the simulation system mission requirements. OSM’s Generic Sonar Simulator provides a parameterised sonar model that is capable of generating sonar output data (picture and trackers) for a large range of array configurations and processing capabilities. This may be linked to a real Sonar Display Subsystem or to OSM’s generic sonar display that can be tailored to the client’s requirements. A separate Audio Simulator link to the Sonar Simulator to provide real time audio data streams based on the array configuration, representing a steered beam containing all acoustic sources defined within the scenario. Various modes of generating the audio (synthetic or recorded) allow the system to be used for all levels of Acoustic Analysis training.

3D Visualisation
Visualisation of a training environment is available through our 3D photo-realistic visual generation system. For applications such as bridge mock-ups, periscope mock-ups, and other maritime uses, the 3D visualisation includes all vehicles in the scenario, land masses and dynamic seascape. For undersea applications such as fixed cameras on ROVs, sea floor topography is also represented. All vehicles interact with the seascape and are positioned geographically accurately based on a standard earth models such as WGS-84. The visualisation system also provides recording for later use as a debrief system.
