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.

One such system supports 1 – 4 independent, dual redundant MIL-STD-1553 channels with BC and multiple RT simulation and Bus Monitoring capabilities. Each individual channel can be Dual Function (BC, BM or multiple RTs (1-32) and BM simultaneously) or Full Function (BC, multiple RTs and BM simultaneously). It supports connection to Central Checkout Systems (CCS) and can also be combined in the same unit with other data networks (SpaceWire, CAN, SpaceFibre, WizardLink, etc.).

“The iSAFT 1553 Front-End is powered by Alta Data Technologies (AltaDT) 1553 hardware modules”


The iSAFT MIL-STD-1553 (MilBus) Front-End supports ECSS-E-ST-50-13C services during BC and RT simulation (time distribution, communication synchronization, get/set data, data block transfer and terminal management services).

The system is fully compliant to the general EGSE requirements for space missions and relevant ECSS standards. It is based on the iSAFT graphical tool chain, for the configuration/management of the simulation, locally through the GUI or remotely through programming APIs. It is a proven solution with more than 100 installations in multiple EGSE test benches across Europe, US, South Korea. It consists a powerful device for the validation of on-board data networks at early stages, minimizing costs and schedule.


The iSAFT 1553 Front-End is offered as a Rackmount System:
