iSAFT Recorder SpaceWire / MIL-STD-1553 / CAN

iSAFT SpaceWire / MIL-STD-1553 / CAN Recorder is an advanced, integrated, 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, MIL-STD-1553 and/or CAN protocol family.


The iSAFT SpaceWire / MIL-STD-1553 / CAN Recorder is capable of capturing data packets on multiple SpaceWire links, MIL-STD-1553 and/or CAN buses, 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.
Powerful HW platform (high processing power, up to Tbytes storage capacity), advanced file and recordings management (auto-archive, disk cleanup, file system and disk optimization, etc.).
iSAFT graphical tool chain (Runtime engine, iSAFT Console, offline analysis with the Wireshark Protocol Analyzer, recordings management).
Capturing & recording of large volumes of traffic from multiple SpaceWire links, MIL-STD-1553 and/or CAN buses.
Off-line analysis of multi-gigabyte traffic logs. Chronological merging of recorded traffic (i.e. from SpaceWire, 1553 and CAN) for complex topologies.
Event-trace trigger & selective tracing (filtering) support, available plug-ins and statistics for various protocols.
Graphical tools for local/remote control, data recording, managing, searching and filtering the recordings.
Export of traffic recordings to XML, PostScript®, CSV, or plain text, user selected protocol fields per packet.
Interfaces with EGSE Central Checkout System.
Open APIs to 3rd-party applications, support for customization, adaptations to customer needs.

Based on an open architecture and modular design, iSAFT Recorder is a future-safe, cost-effective and already validated solution for demanding EGSE activities. One iSAFT Recorder station can simultaneously record data from different networks, store data on its hard disks, manage recorded files, interface to Central Checkout System (CCS) through EGSE SCOE interfaces, etc. It completely replaces the need for multiple separated elements in your testbed (dedicated SpaceWire or 1553 recorders, separate IRIG receivers/sources, dedicated stations for data recording and connection to CCS, etc.). It is fully compliant with all standards and certifications required to install it on a flight equipment/mission EGSE (FMEA, hazard/safety analysis, CE compliance, etc.).
