MAK ONE: Planet Earth’s “Digital Twin” for Training and Experimentation

The world is an infinitely complex place, and interactions between people, systems, and the environment are exceedingly difficult to model. Historically, simulation solutions reduce these complexities to the bare minimum so that an environmental representation can be achieved within the limits of the current technology. This approach is certainly necessary. It enables us to develop focused tactics, techniques, and procedures training simulators, to assist "low-level units [to be] masters of their craft" as General McConville said at a presentation to the Association of the US Army (AUSA).

This reductionist approach, however, tends to result in lots of simulation assets each designed to solve a very specific problem, but generally lacking the flexibility to be integrated into the types of complex multi-domain systems needed to address defense planning in the modern world.

To stay ahead of our potential adversaries, paraphrasing General Charles Q. Brown, we need a robust, lifelike, simulation environment to exercise joint all-domain command and control while we innovate through experimentation and rapid prototyping.

Building a synthetic environment detailed enough for individual training and robust enough to match the complexity of our operational environment requires a new approach, a broader vision of how we create our simulation environments. Fortunately, compute, graphics, display, and networking technology have advanced significantly over the years. Geographic information has become increasingly available. COTS software has become more powerful than ever. We can now afford to start our simulation designs with a whole world synthetic environment that we can join and extend to meet our specific training and experimentation objectives.

The MAK ONE Synthetic Environment
The MAK ONE Synthetic Environment, a simulation model of the world and its inhabitants, meets this vision. This 'Digital Twin' of planet Earth provides the context for multi-domain training and experimentation. It includes the planet's surface that people walk on and vehicles drive across; it includes the dynamic oceans and rivers that ships and boats float on; it includes the atmosphere that aircraft fly in, and even the space above that satellites orbit through.

Conjuring this world into existence requires the confluence of many technologies:
  • A Terrain Engine to construct the three-dimensional model of the world (terrain, buildings, roads) and to model the dynamic aspects of the environment (clouds, waves, weather);
  • A Terrain Server to provide geographic data to the Terrain Engine;
  • A Simulation Engine to model the dynamics and interactions of each moveable entity (ground vehicles, aircraft, satellites, ships, human characters, and animals);
  • A Behavior Engine to give the computer generated forces intelligence;
  • Player Interfaces to enable participants to take interactive control of individual entities;
  • A Render Engine to present visual and sensor scenes of the environment to participants;
  • Graphical User Interfaces to enable operators to create and manipulate scenarios;
  • And finally, Network Interfaces to fill the environment with human behavioral data collected from the real world and to connect simulations so they can participate in the environment.

This modular architecture is essential. It makes possible the creation of simulation solutions that are simple or exceedingly complex. The MAK ONE COTS software model enables system designers to start with products that address the core needs (First-person simulator, Computer Generated Forces, Image Generator) out of the box and it also provides Application Programmer Interfaces (APIs) that allow developers to extend every aspect of the simulation to add specific models and functionality into the common synthetic environment.

The combination of modeling approaches (scenario planning, interactive participation, connecting in remote simulators, and injecting live data feeds) enables the simulation environment to meet both training of individual skills and complex all-domain operations. MAK ONE is the whole world synthetic environment that can be extended in any direction to meet our customers' specific training and experimentation objectives.
