“…Since EGSEs play a key role during the integration and validation phases of the spacecraft life-cycle and given the large adoption of SpW protocol, some test equipment capable of supporting this standard have been designed, such as: STAR-Dundee SpaceWire EGSE and Device Simulator Mk2 , which comprises two SpW interfaces and makes use of USB3.0 as a Host-PC interface [ 8 , 9 ]; 4Links Diagnostic SpaceWire Interface (DSI) , which comprises eight SpW interfaces [ 10 ]; IngeniArs SpaceART , a general purpose SpW EGSE, including four SpW interfaces and Ethernet/PCIe interface to Host-PC [ 11 , 12 , 13 ]; Some SpW/SpaceFibre (SpFi) EGSE solution based on PXI industry standard have also been presented in [ 14 , 15 ]. …”

“…The SpaceART SpaceWire Sniffer is a link analyser part of SpaceART product family. SpaceART ( Figure 4 ) is a complete testing solution for high-speed links in space applications [ 12 , 13 ]. It can operate as a standalone general-purpose SpW EGSE, generating and consuming SpW packets in real-time, or it can be customized to provide specific behaviour, as in [ 5 ], where it is used to generate and process data to emulate a distinct scenario.…”

The on-board communication standard adopted in current generation space missions of the European Space Agency, and many other agencies as well, is SpaceWire (SpW). In a SpW network, data are exchanged as well-formed packets, whose structure offers low packet overhead and allows developers to tailor their implementation for SpW applications. The development of SpW-compliant devices requires a specific set of test instruments, namely Electrical Ground Support Equipment (EGSE), to verify the correct functionality of SpW units under test. An example of a SpW EGSE is the SpaceART EGSE Emulator, an EGSE for generation and processing of SpW packets for a time-constrained use-case scenario. This EGSE has been developed to address a mission-related SpW communication between a device and an Instrument Control Unit (ICU). It has allowed the generation and processing of specific SpW packets, which cannot be provided by the mostly used general-purpose SpW EGSEs. In this scope, the SpaceART SpW Sniffer, a SpW link analyser for unobtrusive monitoring of SpW link, has been employed to run a comprehensive set of tests and provide further information on the considered scenario. The SpaceART EGSE Emulator-ICU communication has been thoroughly tested through the SpaceART SpW Sniffer, unobtrusively analysing the exchanged data and allowing to assess the compliance with the defined time constraints from an external point of view. The use of the Sniffer has been crucial for testing the on-board communication, providing important support for the success of the mission employing the tested ICU.
