Presto satellite simulation bench

PRESTO (PRoteus Engineering Simulator for Tests and Operations) is the real-time satellite simulator for the Proteus series, used to:

  • validate operational procedures of the ground segment during system tests
  • train operators on the command-control centre for Proteus satellites
  • provide expert analysis of problems met in orbit

It is a set of software running on Linux PC and composed of:

  • representative models of the bus system, notably the data handling unit (DHU) integrating the real flight software for the mission
  • a simulation kernel named PRESTOK sequencing tasks and insuring the speed of real-time or accelerated-time tests
  • a naming database enabling data exchange between models
  • a command-control interface through TM/TC functions

This simulator is adapted for each Proteus mission by modifying the payload module software and, if necessary, by an upgrading the bus system modules if the bus evolves.
