iSAFT Protocol Validation Platform



iSAFT is an advanced, integrated, high performing, modern platform for the simulation, validation & monitoring of a wide range of satellite/spacecraft  on-board communication protocols and data networks. Its variety of  features makes it suitable for use in many different areas.


Rapid Prototyping/Evaluation
Implementation of new protocols, experimentation with various protocol features (parameterization of protocol variables, exclusion/inclusion of protocol optional functions, combination of multiple protocols, etc.).
Device Simulation
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.
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.
