Full software validation facility

Features / technical details

The full software SVF development has been initiated by 2001, with the following main drivers:

• Be based on the full software satellite simulators by sharing the same simulation infrastructure and spacecraft models
• Support on-board software validation for both 1750A and ERC32 target processors,
• Provides additional features dedicated to software validation
• Achieve a high level of compatibility with hybrid SVF at user interface level,

Full software SVF key features

• Binary flight software execution by means of a processor emulator (1750A and ERC32 are currently supported).
• On-board computer (with or without redundancy) and on-board data bus (OBDH, 1553) simulations.
• Software simulation of every spacecraft equipment: AOCS, Electrical power, Thermal, Pay-loads with adequate representativity level.
• Real-time execution in simulated time
• Capability to run faster than real-time
• Simulation models scheduling capability to offer a full deterministic simulation.
• Flight software source level debugging using gdb
• Monitoring and control features through sequences (ELISA language) enabling flight-software source level debugging: breakpoints, step by step, data read/write, event triggering on read/write access to specified memory.
• Models execution control, synoptic display, logbook, archiving and analysis capabilities.
• State vector saving and restoring

Key features

• Targeted to 1750A or ERC32 on-board processors
• Hosted on SUN/Solaris or PC-Linux workstations
• Source level debugging with gdb
• Simulation monitoring and control and flight software debug by means of ELISA sequences,
• Object distribution implemented by Orbix or OmniOrb
• Models execution by SIMIX real-time kernel

Categories

• Software

Applications

The full software SVF is in use or in development in the frame of the following space programs:

• Telecommunication satellites (E3000 based) ·
• Pléiades observation program
