Congratulations to ESA and to the academic and industry teams involved with Rosetta.

Rosetta was one of the first missions to use the IEEE 1355 standard, which was the immediate precursor technology to SpaceWire. Engineers from 4Links contributed to these standards before either of the 1355 or SpaceWire Working Groups was established. We are delighted to see the outcomes from this technology in Rosetta, and we have appreciated the experience from Rosetta that has contributed to the evolution from IEEE 1355 to SpaceWire, and to SpaceWire now being built into more than 100 satellites world-wide.

4Links SpaceWire

4Links test equipment reduces SpaceWire development cost and time, and increases what can be achieved within a limited budget. It is unmatched in its bug detection capabilities, its diagnostics, its instrumentation of time, and its ability to test SpaceWire networks remotely over the Internet.

Like SpaceWire itself, 4Links test equipment scales, from testing a single device up to coordinated testing of tens or hundreds of SpaceWire nodes. Easy upgrades minimise equipment costs over the life-cycle of a project. All of these help to solve problems quickly, before they incur expense and delay. Customers using 4Links test equipment have rapidly detected - and solved - problems that had long remained undetected or unsolved.

The 4Links Diagnostic SpaceWire Interface

For customers needing a second opinion on their own designs, or an evaluation of a SpaceWire product that they intend to use, 4Links offers SpaceWire consultancy that builds on the unique capabilities of our test equipment and our unique experience of developing with SpaceWire. We also have developed a range of SpaceWire IP products, from simple interfaces to complex systems-on-chip, all based on the efficient and robust SpaceWire design that has been proven by so many users of our test equipment.

4Links has recently exhibited at four major space-related events:

At these shows, we demonstrated an example SpaceWire network, representative of such a network in a satellite, that was able to recover from faults such as removed cables and switched-off subsystems. We showed this to many of our existing customers, and created new interest in SpaceWire at all of these gatherings.
