The iSAFT SpaceWire Simulator / Recorder is an advanced Data Front End with traffic generation capabilities that simulates SpaceWire devices or Instruments, enabling S/C integration tests before the availability of Flight Models. It also constitutes a high performing, modern network traffic capture, recording and analysis tool for the validation of satellite/spacecraft on-board communication protocols and data networks implementing the SpaceWire protocol family.

It provides a 4 – 12 port SpaceWire interface with advanced traffic generation and asynchronous transmission capabilities. It is capable of transmitting/receiving data packets over multiple SpaceWire links, time stamping received packets, and capturing transmitted/received traffic to a powerful Protocol Analyser. It is based on the iSAFT graphical tool chain, for the configuration/management of the simulation (locally or remotely). The iSAFT SpaceWire simulator is a powerful device for the validation of on-board data networks at early stages, minimizing costs and schedule. It can be part of EGSE Data Front Ends and implement the core functionality of an EGSE controller.

As a recorder it is capable of capturing data packets on multiple SpaceWire links, time stamping, recording, and delivering them to a powerful Protocol Analyzer for further processing & analysis. Operating on a multi-Gbytes powerful HW platform, the SW environment is based on the iSAFT graphical tool chain, thus allowing the management, filtering & searching of the recordings. It is used for troubleshooting and problem solving at various development stages, minimizing the impact on cost and schedule.
