TESS models are based on established science and engineering equations and algorithms and can be directly traced for verification to established sources.

With a source code version of TESS, users can conduct comprehensive independent verification of the simulations. Many TESS return customers have carried out such independent verification.  To support this verification activity TESS Software Description Documents describe the simulation system model hierarchy, equations and algorithms in great detail while also providing reference to their source in scientific and technical literature.

The Defence Research Laboratory in Ottawa, Canada has carried out extensive independent verification. Using hardware-in-the-loop trials, a number of countermeasure / radar engagement outcomes were matched to TESS generated results demonstrating the validity of TESS’s models and non-linear functions.

Documentation on some of these verification and validation tests is available upon request.
