A second generation of our widely used SpaceWire PCIe board is now available with several improvements over the original product. The SpaceWire PCIe Mk2 board is a three port SpaceWire interface and router device, suitable for all stages of SpaceWire equipment development: initial SpaceWire evaluation, instrument simulation, control system simulation, unit testing, and spacecraft equipment integration support. The board is backwards compatible with the original SpaceWire PCIe (Mk1) board and adds extensive fault protection to meet most FMEA requirements. The new board also includes two external triggers not present on the Mk1, to enable synchronisation of packet transmission with external events and signalling of packet reception, and other events, to external equipment.
To facilitate fault protection, the SpaceWire PCIe Mk2 is powered from both +3.3V and +12V, compared to the Mk1, which is powered by +3.3V only. The power for both +3.3V and +12V supplies is taken from the PCIe slot that the board is plugged into.
As with the SpaceWire PCIe Mk1 and many of our other SpaceWire and SpaceFibre products, the SpaceWire PCIe Mk2 is supported by STAR-Dundee’s STAR-System software, making it simple to move from another product to the PCIe Mk2. Example command line applications are provided with source code to demonstrate common tasks, and to test a device’s throughput and latency. GUI applications are also provided to support the configuration of devices, the transmission and reception of packets and time-codes, and to inject errors.
SpaceWire PCIe Mk2 boards have now been shipping to initial customers for several months while we have worked to build up sufficient stock to fulfil future orders.
Due to our ongoing success and to allow us to further grow, we’re seeking to recruit several new employees in different areas of the business.
The positions we’re looking to fill include an Electronics Test Engineer, a Sales and Procurement Assistant, and several Electronics and FPGA Engineers. Each of these roles will provide the opportunity to contribute to the development of STAR-Dundee’s innovative spacecraft on-board network technology and electronic test equipment. This technology is already being used on spacecraft monitoring the Earth’s land, oceans and atmosphere, exploring Mars, visiting and bringing back samples from asteroids, mapping the stars in our galaxy, providing GPS and communication services, preparing to resume human exploration of the moon, and on many more Earth observation, scientific, astronomy and exploration missions.
As well as being a leading supplier of spacecraft on-board network technology and electronic test equipment, STAR-Dundee is an employee-owned company, with over 50% of the company shares owned by an Employee Ownership Trust on behalf of the employees. Staff are represented on this Trust and on the Board of Directors, and also benefit, when there’s a dividend payment to the other shareholders, with a tax-free or partially tax-free bonus.
The successful candidates will be based in our office in the heart of Dundee, Scotland, a renovated 19th century town house overlooking the Tay estuary. Dundee, Scotland’s fourth largest city, was listed by Lonely Planet in 2018 as one of the top ten best European destinations to visit and praised for its ‘head-turning’ urban redevelopment.
Further details on the vacancies, including detailed job descriptions with information on applying, can be found on our Vacancies page.
It was a momentous occasion earlier this week for STAR-Dundee as we celebrated our 20th anniversary!
Started in 2002, STAR-Dundee was born out of the Space Technology Centre at the University of Dundee, which led the technical work on the SpaceWire standard, something which staff at STAR-Dundee have been instrumental in for more than 20 years.
We are very proud to be a world leader in both SpaceWire and SpaceFibre technology.
We would like to take this opportunity to thank all our talented and dedicated employees at STAR-Dundee for making our success story possible.
And to the valued users of our products, we express our thanks to you for trusting us for many years and making us the leader in our field.
We are excited about the opportunities that lie ahead and drive us to extend our track record of innovation and success.
The STAR-System software suite has provided the drivers, APIs and applications to our SpaceFibre and SpaceWire products for over 10 years and continues to be updated with new features and improvements in each release. The latest major release, version 5.00, includes two features which we regularly receive requests for: an API for the Python programming language and a new Linux installer supporting ARM targets such as the Raspberry Pi and BeagleBone.
Other new features include a new API to support creation and processing of CCSDS Space Packet Protocol and Transfer Frame packets, and new graphical applications providing RMAP Initiator and Triggering functionality. The Source and Sink graphical applications have been updated to include graphs to visually represent statistics when transmitting and receiving, while there are numerous other improvements and bug fixes.
Version 5.00 has been successfully tested on Windows 11 and Linux kernel compatibility has been tested up to kernel v5.16.9. As with all STAR-System releases, version 5.00 is backwards compatible with previous releases and so any software developed for an earlier version will work with this latest release without requiring any modifications.
STAR-System version 5.00 is now available for download for registered users through the Support area of our website. If you don’t already have access to these downloads, please register your product on our Product Registration page.
Steve has been responsible for leading the development of SpaceWire and SpaceFibre computer network technologies for use on-board spacecraft. SpaceWire is being used in hundreds of spacecraft, costing in excess of $50 billion, which are monitoring the Earth, exploring our Solar System, and studying the universe. SpaceFibre is the next generation of this extremely successful technology, offering high-performance and high-reliability. It is already being designed into its first space applications and flying on two experimental spacecraft, OPS-SAT and NORBY.
Steve has been a constant innovator over the past 26 years since he first moved to Scotland (living in Kirriemuir, Angus) and joined the University of Dundee, where he became Professor of Spacecraft Electronic Systems. He has worked extensively with the international aerospace industry and space agencies across Europe, USA, Japan and Russia, being recognised by the Saltire society for his international scientific work in 2019.
As examples of his world-leading reputation, in 2012 Steve was awarded a Specialist Bronze Award by the Royal Aeronautical Society for his “instrumental role in the inception, development and continuing success of the SpaceWire standard for spacecraft on-board data handling” and in 2013 he was one of the recipients of the European Space Agency (ESA) Award for Teamwork Excellence for the SpaceWire project.
Steve founded STAR-Dundee to help support users of SpaceWire in 2002, spinning the company out from his research group at the University of Dundee. He led the company for 15 years as Managing Director and then CEO. He became CTO in 2017 to focus on engineering and business development activities.
Stuart Mills, CEO of STAR-Dundee said: “Everyone at STAR-Dundee would like to congratulate Steve on this well-earned recognition. In addition to founding and leading the company until 2017, Steve is responsible for writing the SpaceWire, RMAP and SpaceFibre standards, with input from the international space community. As well as being used in many spacecraft, these standards are the key technologies on which STAR-Dundee’s great success has been built.
“In his position as CTO, Steve continues to innovate. In addition to overseeing our world-leading research and development activities, he is also contributing to the development of new open standards which will benefit the wider space community.
“STAR-Dundee would also like to extend our congratulations to all the newly elected Fellows. I am sure their capabilities will be of great benefit to the Academy in its important mission to create a sustainable society and an inclusive economy for all.”
Sir Jim McDonald FREng FRSE, President of the Royal Academy of Engineering, stated: “Our Fellows represent the best of the best in the engineering world, and we welcome these 69 excellent and talented professionals to our community of businesspeople, entrepreneurs, innovators and academics.”
“This year’s new Fellows are the most diverse group elected in the history of our institution. The engineering profession has long suffered from a diversity shortfall and the Academy is committed to changing that, including by ensuring that our own Fellowship community is as inclusive as it can be. It is well established that diverse organisations tend to be more agile and more innovative, and as the UK’s National Academy for engineering and technology, we have a responsibility to reflect the society we serve in addressing the shared challenges of our future.”
Last month we attended Space-Comm Expo, our first in-person event since the COVID-19 pandemic hit, but we have also participated in several virtual events over the past 17 months and will be participating in several more over the coming months. From Monday 9th of August 2021 we will be exhibiting virtually at SmallSat, the 35th Annual Small Satellites Conference. Our engineers will be online from 9am to 1pm MT from the 9th to the 12th of August to answer any questions you may have, and we will also have a demo each day at 10am MT. The demos are listed below and there are more details, with links to join each event on the SmallSat Demos page of our website:
Monday, 9th August 2021: Overview of STAR-System for LabVIEW
Tuesday, 10th August 2021: SpaceWire Link Analysis using the Link Analyser Mk3
Wednesday, 11th August 2021: STAR-Ultra PCIe: Multi-Lane SpaceFibre Interface and Link Analyser

The other events we currently plan to attend this year are listed on our Events page.
Following the completion of the Brexit transition period on the 31st of December 2020, the UK will no longer be a participant in the European Union Customs Union or European Single Market. STAR-Dundee would like to assure our customers that we are well prepared for this change and we will endeavour to ensure that there is the least possible disruption to you in the delivery of any orders.
Our preparations for this date have been ongoing for some time and we were awarded Approved Exporter Status in 2019. Holding the status of Approved Exporter simplifies export formalities and allows us to certify the preferential origin of our products, via a specific declaration on our invoices or commercial documents. This means we do not need to apply for movement certificates for each export, for example. We are also grateful to our logistics partners and to our distributors, who continue to help us to ensure that orders are delivered in a timely manner.
STAR-Dundee continues to have a presence in Europe, with our wholly owned subsidiary, STAR-Barcelona, based in San Cugat, to the north of Barcelona, Spain. STAR-Barcelona’s activities are primarily focused on research and development, ASIC design and IP cores related to SpaceFibre.
Should you have any questions or concerns, please do not hesitate to get in contact.
We will have lots of exciting information to share during the event. On the first day, one of our engineers will present a paper titled “SpaceFibre for FPGA: IPs and Radiation Test Results”. In addition to information on the implementation footprint of our SpaceFibre Single-Lane, Multi-Lane and Routing Switch IPs on several Xilinx and Microchip FPGAs, this presentation will also include initial radiation test results of the Microchip RTG4 SerDes performance with and without our SpaceFibre IP.
Another of our engineers will be presenting a webinar at our virtual booth on the third day of the event, titled “Very High Speed SpaceFibre Interfacing and Analysis with the STAR-Ultra PCIe”. This will include a demonstration of the STAR-Ultra PCIe, a PCIe board providing two quad lane SpaceFibre interfaces, capable of data rates in excess of 10 Gbit/s. The STAR-Ultra PCIe can also act as a link analyser for monitoring and recording the traffic crossing the link and includes a suite of powerful software applications to easily access the features of the device.
Throughout the event, our team will be available at our virtual booth to answer any questions on SpaceWire, SpaceFibre, our products and related technology. There is lots of other useful content available at our booth which will continue to be online after the show ends and until the end of the year.
It has been 16 years since the first generation of the SpaceWire-USB Brick was released and the Brick has since become a familiar product in space organisations across the world. Numerous improvements have been made to the product over the years including new features, improved performance and support for new software and operating systems. Many of these improvements have been delivered in the form of software or firmware updates available from our website to existing users.
Sometimes improvements have been made to the physical hardware, requiring a new generation of the product to be released. Five years following the release of the Brick Mk3, we have taken the opportunity to add some new features to the hardware, resulting in the new SpaceWire Brick Mk4. Although the enclosure looks similar to the Brick Mk3, internally the new device features enhanced FMECA protection while the rear panel now includes a grounding stud and a power status LED.
The Brick Mk4 is connected to a Windows or Linux PC over USB and provides high throughput and low latency access to two SpaceWire ports. External triggers allow external equipment to signal an event to the Brick Mk4 or the Brick Mk4 to signal external equipment. Both interface and router modes are supported and the Brick Mk4 can be used in all stages of SpaceWire equipment development: initial evaluation, instrument simulation, control system simulation, unit testing and integration support.
As with all of our recent interface and router products, the Brick Mk4 is supported by our STAR-System software suite, making it simple to move from one of our other products to the Brick Mk4. Importantly, the Brick Mk4 is backwards compatible with the Brick Mk3 and includes all features present in the Brick Mk3.
The 2020 edition of the Small Satellite Conference is being held virtually and our participation will include virtual demonstrations of some of our new and existing products every day of the conference. You can find more details on our Live Events page, but the demonstrations will be as follows:
These demonstrations will take place at 4pm British Summer Time/9am Mountain Daylight Time. Later in each day (6pm BST/11am MDT) we will be hosting an open question and answer session where you can drop in to speak to our engineers or listen to the discussion.
For many years, STAR-Dundee has offered SpaceWire Lab Cables which are compatible with the SpaceWire standard but are lighter and more flexible than flight-qualified cables. With the publication of Revision 1 of the SpaceWire standard in 2019, a new cable assembly type has been introduced and STAR-Dundee supports both original and new types of assembly.
The cable assembly present in previous revisions of the standard has been named Type AL in the new revision of the standard, with the “L” standing for legacy. The inner-shields of Type AL cable assemblies are connected to pin 3 of the connector at the transmit end of the cable only. The SpaceWire Lab Cables we have previously offered as our standard off the shelf cables have conformed to this arrangement.
The new cable assembly type is named the Type A cable assembly. These differ from Type AL cable assemblies in that the inner shields are connected to the connector shell at both ends. Pin 3 is not connected in the Type A cable assembly.
Type A cables are recommended for all new applications.
We have been providing Type A cables on request for some time, but we’ve now added the option to select either Type A or Type AL cable assemblies when requesting a quotation for SpaceWire Lab Cables and we will be holding stock of both types of cables. If you’re unsure of which type to order, please get in contact and we’ll be happy to answer any questions.
STAR-Dundee’s SpaceWire PXI platform has now been updated to include a number of enhancements to single point of failure FMECA (Failure Mode Effects and Criticality Analysis) protection. The SpaceWire PXI Mk2 range of products now supersedes the original SpaceWire PXI products, offering all the features present in the original products and full backwards compatibility.
At STAR-Dundee we continually work to improve our products. When these improvements are to software or to a device’s firmware, we make these updates available through our website’s Product Support section. You can gain access to these downloads by registering your product. When the update is to the hardware, we endeavour to ensure backwards compatibility with previous generations of the product. We indicate the version number of a product using the mark designation system, abbreviated to Mk. For example, the SpaceWire PXI Mk2 (Mark Two) is the second generation of our SpaceWire PXI product range.
The SpaceWire PXI Mk2 is available in the following variants:
SpaceWire PXI Interface Mk2 4HP
SpaceWire PXI Interface Mk2 8HP
SpaceWire PXI Interface Mk2 with RMAP Target 4HP
SpaceWire PXI Interface Mk2 with RMAP Target 8HP
SpaceWire PXI Router Mk2
The SpaceWire PXI Mk2 products can be used in cPCI or PXI backplanes, provide link speeds of up to 400 Mbit/s and, as with our other interface and router products, are accessed using our STAR-System software suite. The 8HP variants of the PXI Interface Mk2 and PXI Interface Mk2 with RMAP Target have 4 general purpose bi-directional triggers on the front panel which can be used to sequence events such as the transmission of time-codes or data packets, or to indicate events to an external device such as an oscilloscope. A full FMECA guide for the SpaceWire PXI Mk2 boards is available on request.
