iSAFT 1553 (MilBus) Front-End


The iSAFT MIL-STD-1553 (MilBus) Front-End is an advanced Data Front End with BC, RT simulation and traffic generation capabilities that simulates MIL-STD-1553 devices or instruments, enabling S/C integration tests before the availability of Flight Models.

It also constitutes a high performing, modern network traffic capture (Bus Monitoring -BM), recording and analysis tool for the validation of satellite/spacecraft on-board communication protocols and data networks implementing the MIL-STD-1553 protocol family.

It provides a 1 – 4 channel MIL-STD-1553 interface with BC and multiple RT simulation and Bus Monitoring capabilities. It is capable of simulating a BC or multiple RTs over the MIL-STD-1553 buses. It is based on the iSAFT graphical tool chain, for the configuration/management of the simulation (locally or remotely). It consists 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 Bus Monitoring Tool (Recorder), it is capable of capturing data packets on multiple MIL-STD-1553 buses, time stamping, record-ing, 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.
