One of the many use cases for FPGAs is signal processing and working with high speed ADC and DACs. This weeks blog is a long one looking at the combining the ZU 1CG board, Zmod Arbitrary Waveform Generator, and PYNQ to create a project which we can use to generate waveforms. #fpga #digitalsignalprocessing #dsp #embeddedsystems #electronics #embeddedsoftware https://lnkd.in/evwF_fbY

Interfaces are the key to great team flow. In spacecraft mission development, interface reviews are critical. They ensure that every system, subsystem, and component works seamlessly together — whether it’s hardware, software, or ground systems. But here’s the punchline: it’s not just about the technology. It’s about the team. 1 / Defining interfaces defines collaboration Every interface is a connection point, not just between systems but between teams. When interfaces are clear, responsibilities are clear. When they’re not, teams end up working in silos—or worse, pointing fingers. 2 / Interface reviews build accountability These reviews force everyone to sit down and align. Are the signals, protocols, and connections right? Are expectations between teams clear? Good interface reviews aren’t just technical—they’re relational. 3 / Great interfaces = Great flow When interfaces are well-designed, teams can trust each other and focus on execution. They’re not worried about what happens “downstream” or “upstream.” That trust leads to better decisions and faster problem-solving. When you're leading any cross-functional team, interfaces are where flow happens. When the interfaces work, the mission works — and so does the team. Thoughts???

Reposting for my energy industry colleagues and contacts: at some point, you're probably going to incorporate sUAS/drones into your organization or workflows and while the regulatory conversations are usually the most boring/frustrating, they're also the most important. This will be a good webinar to learn about a subject that will very likely be in your near future and provide a partial understanding of what challenges may lie ahead.

Exciting news from the aviation tech sphere as uAvionix Corporation secures a Federal Aviation Administration (FAA) Broad Agency Announcement (BAA) contract to revolutionize C-Band frequency management for uncrewed aircraft systems (UAS) command and control (C2) communications. This milestone represents a significant leap towards widespread commercialization of UAS operations, especially in scenarios involving multiple UAS operating closely. Cyriel Kronenburg from uAvionix emphasizes the critical need for reliable and deconflicted communications among multiple UAS operating in shared airspace, particularly in scenarios such as medical delivery and first response services. The use of licensed spectrum like C-Band is key to ensuring robust communications for UAS, but the current manual assignment process isn't scalable. uAvionix’s Dynamic Frequency Management System (DFMS) demonstrates a promising solution, leveraging protected C-Band spectrum for efficient frequency allocation and deconfliction. This contract underscores uAvionix’s commitment to advancing UAS technologies and aligns with regulatory initiatives like the FAA Reauthorization Act of 2018. By showcasing the capabilities of DFMS through the SkyLine Platform, uAvionix aims to facilitate seamless and reliable C2 communications for multiple UAS, setting new standards for airspace integration and safety. Stay tuned to our blog for an in-depth look at uAvionix’s groundbreaking work in UAS communications and spectrum management. #AvfoilNews #uAvionix #FAAContract #UASCommunications #CbandFrequencyManagement

How it feels when everything goes wrong: (The hardships of hardware development) [𝗽𝗮𝗿𝘁 5] I have to rewind from the spring of 2023 to the fall 2022. We hired an agent to help us fundraise in the fall of 2022. The agreement was the first part of the money on our account in February. When they failed to do that, our own investors pulled the bridge financing. Now we had 3 months before we ran out of money. It was fair enough. We had struggled with motor problems for 6 months. The progress on the flying prototype seemed very little. In the end, we found out there were manufacturing errors on them. The countdown timer is 3 months now. Fugg!! Well, Travis James Mathers and I were not ready to give up. We geared up, prepared ourselves for war. I had to fire the whole team due to Danish rules around responsibility. Here is the status at this point: - A fired team with 3 months of resignation, - A prototype with motors that had been causing problems - There is no regulatory approval to fly outside. Okay, here we go! We put in all our efforts to get regulatory approval so we could fly outside and do a demonstration for a potential customer, which would probably get us our bridge financing back. 1.5 months later, we got our regulatory approval as the only ones in Europe able to do onshore and offshore operations with this heavy drone for cargo delivery for wind turbines. 2 months later, we fly outside for the second time, and at about 25 meters of height, we have a small glitch on a motor that causes instability that makes the drone crash into the ground. At this point, all the escape hatches are open for us to jump into and give up. Double FUGG!! Follow me for the next part of the story. If you love what you do, fight for it with everything you have. -MK

Really great article on Space! Highlights Rocket Lab and their mission of small launches their Electron rocket has filled. It goes on to discuss the Neutron that is a medium lift vehicle. Rocket lab focuses on the taxi service where it takes individual payloads to specific orbits, but the new Neutron rocket is meant to compete with SpaceX and its Falcon 9. The article further discussed start ups, such as Relativity Space and ABL Space Systems. I was quoted around the maturity of businesses in this segment and discussed M&A activity. I highlighted that, "... for a company to be a consolidation target it needs some enterprise value; it needs sales and employees and contracts." I further went on to say that, "... those pure-play space companies, they are going to have a harder time because it is a slower cycle, versus a company that gets into space with a diversified book of business and will probably be more successful." #aerospace #space #mergersandacquisitions #thefactorydoctor https://lnkd.in/gsNrw2cA

Variational integrators for stochastic Hamiltonian systems on Lie groups: properties and convergence by François Gay-Balmaz https://lnkd.in/eS-qtqPU https://lnkd.in/eA_UjKJN We derive variational integrators for stochastic Hamiltonian systems on Lie groups using a discrete version of the stochastic Hamiltonian phase space principle. The structure-preserving properties of the resulting scheme, such as symplecticity, preservation of the Lie-Poisson structure, preservation of the coadjoint orbits, and conservation of Casimir functions, are discussed, along with a discrete Noether theorem for subgroup symmetries. We also consider in detail the case of stochastic Hamiltonian systems with advected quantities, studying the associated structure-preserving properties in relation to semidirect product Lie groups. A full convergence proof for the scheme is provided for the case of the Lie group of rotations. Several numerical examples are presented, including simulations of the free rigid body and the heavy top.

It is amazing what we can do with smaller FPGAs. This week my blog creates a System Controller application using a Spartan 7. Such a thing can be used to control the clocking, power, overall system for more complex devices such as MPSoC or Versal. #fpga #electronics #embeddedsystems #engineering #electronics #embeddedsoftware https://lnkd.in/eKRQnuyx

Riemannian Medians and Means With Applications to Radar Signal Processing https://lnkd.in/ecDr8KkE Abstract: We develop a new geometric approach for high resolution Doppler processing based on the Riemannian geometry of Toeplitz covariance matrices and the notion of Riemannian p -means. This paper summarizes briefly our recent work in this direction. First of all, we introduce radar data and the problem of target detection. Then we show how to transform the original radar data into Toeplitz covariance matrices. After that, we give our results on the Riemannian geometry of Toeplitz covariance matrices. In order to compute p -means in practical cases, we propose deterministic and stochastic algorithms, of which the convergence results are given, as well as the rate of convergence and error estimates. Finally, we propose a new detector based on Riemannian median and show its advantage over the existing processing methods.
