Economic & portable replacement of a device in the testbed (SSMM, RTU, RMAP responder, etc.).
Functional/Conformance Testing
Execution of nominal tests to ensure that a device (System Under Test) is operating in compliance with the applicable ECSS standards. Error injection at various protocol layers to validate the response of the devices/networks in erroneous conditions.
Traffic Generation
Bulk traffic injection at higher & lower protocol layers for performance evaluation and network dimensioning.
Protocol Analysis/Recording
Message decoding & recording, filters, start-stop triggers, intelligent error detection, export results, statistics.
iSAFTpvpfeatures-1024x931
The iSAFT protocol validation platform can be used for rapid prototyping & evaluation of new network protocols/features, for functional testing and stress testing. Moreover it can be used for device simulation (SSMM, RTU, etc.) as well as for protocol analysis & recording. Based on an open architecture and modular design, iSAFT is a future-safe, cost-effective and already validated solution for demanding ESA activities towards the future evolution of S/C on-board data handling/networks.
