TEVALIS is a licensable product that allows the licensee to use GSTVi. It contains aligned/compatible versions of GSTVi; SIMSAT; Ground Models; and the SLE API.
The Ground Systems Test and Validation infrastructure (GSTVi) provides a family of test components for testing of ground systems during all phases of development, integration, configuration, upgrade, and operation.
Depending on its configuration and deployment, the GSTVi system replaces the space segment and/or parts of the ground segment by a collection of software components. In principle, the GSTVi can simulate the complete operational chain from the Mission Control System (MCS) to the spacecraft and back.
The systems under test are introduced in the chain and interface with the appropriate GSTVi models. In addition, specific GSTVi configurations are used to connect the MCS with the EGSE/FEE during system validation tests (SVT).
For instance, supporting GSTVi components such as the Recorder and Replayer are not shown. The IMBU is actually a hardware unit and is interfaced by a special IMBU I/F component.
