It is time for better simulation !

Easy-to-use synthetic environment for engineers.
Leverage a unique software for your next simulation system

Do you deliver bespoke solutions ?

Then you need an open environment, you need a development system. Break free from black-box gaming software which solely provide parameters to change and like-it-or-leave-it canned features.

Are your tools too complex ?

Let your engineers focus on the solution and not waste their time taming heavy and expensive tools. Do not get bogged down in a single-vendor ecosystem with high annual license fees.

Need modularity ?

You wish to use your favorite graphic engine, embed your own models, doctrines, external devices or third party libraries, but your current CGF or simulation software forbids that or makes it cumbersome ?

Try something new !

Leverage a unique white box SDK to build your next simulation system


Why is vsTASKER the
best solution

By combining visual paradigm and code generation, it is even easier than before to design new models, define bespoke behaviors, assign plans to specific entities and create all kind of scenarios, from a simple test-bed to the most complex distributed trainer.

Regular updates

For more than 15 years, vsTASKER has evolved to adapt to the changing requirements of many customers around the world.

Each project its version

The Control-Command version is ideal for building instrument panels, quick user interfaces or to test complex logic. Thanks to the state machine editor which allows programmers to insert code directly into the machine and generate ready-to-deploy license-free executable products.

With Transport version, designers benefit from a map to draw roads, import maritime routes or airways using ARINC 424 and DDS standards. Train, car, truck and ship trainers can be easily built  and used, combined with an OSG viewer or any 3D graphics engine for the output display.

The Defense version targets military simulations. It provides realistic radio communication models, specific terrain capabilities, HLA, CIGI & DIS support as well as much other great functionalities to speed up the testing of doctrines and connection to other simulators or embedded third party software.

The Defense version can be augmented with Satellite propagators (SGP4 & TwoBody), ground to space communications, an earth viewer (OpenGL and OsgEarth) and an editor to define any orbit based on Kepler parameters or using TLE data from external sources such as Norad.

Publish your website to a local drive, FTP or host on Amazon S3, Google Cloud, Github Pages. Don't be a hostage to just one platform or service provider.

Just drop the blocks into the page, edit content inline and publish - no technical skills required.

Pin-point your code, drag & drop objects, generate code with a mouse-click

vsTASKER is the perfect solution for any customer who needs a versatile tool for his simulations. Whether it is for Defense or Civilian projects, the open infrastructure of the product will satisfy all needs on time and within budget. Many integrators have trusted us over the years with difficult cases and have managed to deliver successful results.

Better simulation is here!

Design your logic graphically using the visual editor and let the code generator do all the coding for you, efficiently and without errors.
State machine and behavior trees will speed up your scenario creation with unmatched simplicity. Design, assign, drag & drop, test and deploy.

Quickly distribute your simulation between various players or use third party graphic engines such as VBS-IG for top quality 3D output.
vsTASKER provides several different means of communications: HLA, CIGI, DDS, DIS, LAN

Use the published and documented API to control all aspects of your simulation. Easily add your own models with parameters or extend the built-in ones very simply.
Define the entity capabilities by attaching as many models as needed using point & click.

Drag & drop predefined objects to easily design your own GUI to interact with your simulation, without having to use external software or integrate with Qt or wxWidgets. Quickly build your OpenGL realistic user interfaces and deploy license free.

Our simulation engine can handle complex logic in real time from 1hz to high frequencies (> 1000hz) and thousands of different entities can run simultaneously inside a scenario.

Design your system database, create your behaviors visually, setup your scenarios using maps, drop entities into your terrains and give them plans, then generate the license free simulation engine.
