STANREC 4800 – AMSP-04 NATO Education and Training Network Federation Agreement and FOM Design

Abstract: Efficient and effective use of NATO and national Modelling & Simulation (M&S) capabilities requires standards for networking and simulation interoperability. The NETN FAFD is a NATO standard recommendation (STANREC 4800) how to represent shared data in distributed simulation environments where M&S services (federates) are connected and federated using the NATO mandated High-Level Architecture standard (STANAG 4603).In March 2018, the NATO Education and Training Network

Evolution of NATO standards for federated simulation

Abstract: NATO and the Nations regularly use distributed simulation based on the High Level Architecture (HLA) interoperability standard. The current release is IEEE 1516-2010. In the NATO context, several official documents are available to standardize the use of HLA across NATO Nations:• STANAG-4603 describing the HLA standard.• STANREC-4800 describing the NATO Education Training Network (NETN) Federation Object Model and the associated Federation Architecture and FOM

Enhancing Simulation Composability and Reuse with Modular FOMs

Simulation composability and reuse have long represented the “Holy Grail” of distributed simulation. The ability to develop simulation components in a way that enables them to be reused as well as the ability to pull together independently developed simulation components have long promised flexibility and cost savings for Department of Defense simulations. While the High Level Architecture (HLA) has provided an interoperability standard enabling simulation

New Object Modeling Opportunities in HLA 4

One of the main success factors of HLA is that it makes it easy to create, maintain and share federation objectmodels (FOM) for distributed simulations. Such models can be developed and extended for almost any domain, for exampledefense and security, space, engineering, medicine and transportation. Particular success stories include the Real-timePlatform Reference FOM (RPR FOM), NATO Education and Training Network (NETN) FOM and the upcoming

Improving Tactical Data Link Simulation Standards To Better Support LVC Exercises

ABSTRACT: The SwAF Air Combat Simulation Centre (FLSC) has taken an initiative called the Air Combat FOM (AC-FOM), which extends the RPR-FOM v.2.0 standard reference Federation Object Model (FOM) to better support aerial combat simulation and further enhance the level of interoperability between various internal and external simulation components. As part of the work of extending the Real-time Platform Reference Federation Object Model (RPR-FOM), FLSC

Towards a Standardized Federate Protocol for HLA 4

ABSTRACT: HLA is a powerful interoperability standard with a rich set of services for information exchange, synchronization and management of federations. These services are accessed through a local RTI library, installed on the same computer as the simulation itself. As new and improved RTI versions are released, or if the user wants to switch RTI supplier, these libraries need to be replaced. What if there

Evolving Standards for Tactical Data Link Aware Simulators

ABSTRACT: The ability to simulate Tactical Data Links is becoming increasingly important in order to more accurately represent the modern battlespace. There is also a need to be able to connect with or simulate commercial use data links such as ADS­B and AIS. LVC applications may rely on the integration between simulation systems and real data links in order to integrate live entities into a

A First Look at the Upcoming SISO Space Reference FOM

SISO SIWzie award winner ABSTRACT: Spaceflight is difficult, dangerous and expensive; human spaceflight even more so. In order to mitigate some of the danger and expense, professionals in the space domain have relied, and continue to rely, on computer simulation. Simulation is used at every level including concept, design, analysis, construction, testing, training and ultimately flight. As space systems have grown more complex, new simulation

Building Scalable Distributed Simulations: Design Patterns for HLA DDM

ABSTRACT: Over the last decades the size of scenarios in distributed simulation has grown considerably, for example in defense training. There is also a demand for larger number of federates within exercises. This means that federation scalability is an area of growing importance. The developers of HLA foresaw this and introduced not only class-basedfiltering, but also the HLA Data Distribution Management (DDM) for instance filtering.

Towards RPR FOM 3: Revisiting the Datatypes

ABSTRACT: Version 2 of the Real-time Platform Reference FOM (RPR FOM) has recently been finalized. It is the most widely used FOM for defense simulations. The original purpose of the RPR FOM was to facilitate interoperability between the DIS protocol and HLA federations. Today it is often also used as a common basis for further adaptationand extensions in US and NATO federations.One of the main

Using HLA Object Models for the Analysis of Cross Domain Security Policies

ABSTRACT: Across defence, training equipment, data and scenarios are likely to have different classification levels. Thus it is sometimes necessary for training to be carried out using a federation of participating systemsrunning at different classification levels, but without compromising security rules. This is usually done using guards and filters to limit the data that may be released from the higher security domain to the lower

Solving Common Interoperability Challenges with HLA-to-HLA Bridging

ABSTRACT: Recently there has been a lot of focus on gateways between different simulation standards, like HLA, DIS and TENA, for example as part of the LVC-AR work and several SISO working groups. Bridgingbetween different HLA federations has received little attention. Still, this is a highly useful technique for solving many interoperability issues. It is currently in use in several large federations.We argue that there

Security in NATO Collective Mission Training – Problem Analysis and Solutions

ABSTRACT: We never fight alone, so we should train together! With missions being joint and combined, we also need to train that way. Given limited budgets and available resources, distributed simulation is rapidlybecoming a necessity for collective mission training. However, due to the characteristics of mission simulations the protection of classified information (e.g. scenarios, weapon and sensor capabilities or doctrines) becomes a serious security challenge.
