Workstation-Based Avionics Simulator to Support Mars Science Laboratory Flight Software Development

Abstract: The Mars Science Laboratory developed the WorkStation TestSet (WSTS) to support flight software development. The WSTS is the non-real-time flight avionics simulator that is designed to be completely softwarebased and run on a workstation class Linux PC. This provides flight software developers with their own virtual avionics testbed and allows device-level and functional software testing when hardware testbeds are either not yet available or have limited availability. The WSTS has successfully off-loaded many … Show more

“…To complement the spacecraft and the MSTB testing venues, a third software-based only testing platform was employed. The Workstation Testset (WSTS) was a standalone softsim environment running on a Linux platform, and it exercised the actual flight software in conjunction with the necessary interface and simulation engines [49]. This venue thus had the broadest availability, as all it relied on was a ubiquitous Linux machine.…”

“…The third widely used testing venue was a software-only environ ment known as the workstation testset (WSTS) [21], Because it was completely instantiated in software on a non-real-time operating system, this venue was not useful for timing or performance consider ations. However, it was very accessible (upwards of 45 instances could be supported concurrently), relatively straightforward to set up and operate, and an excellent venue for testing software/software interactions.…”
