The satellite industry is shifting towards smaller, more efficient satellite designs. Emerging players and established giants are embracing this transformative period by investing heavily in nimble and flexible solutions, such as small GEO satellites. Small GEO satellites are cheaper than traditional GEO satellites, providing access to new customers that might not have considered buying into GEO before. Experts expect the upcoming years to be a test period for satellite manufacturers and operators to test different satellite designs before determining the most efficient one.

SDSs have the potential to revolutionize several market segments in the Space Economy. The research we are developing within the Observatory on Space Economy #ose2024 at the POLIMI School of Management shows that this potential can be fully captured by achieving higher levels of maturity in modularity adoption, going beyond system design solutions and instilling modularity in organisational design and business model innovation Alessandro Paravano Valentina Zancan Victoria Krivova Carlo Negri Osservatori Digital Innovation

Today we show some satellite tracking footage we captured during a recent observation for the KI-SENS Project. The goal was to test the limits of our telescope optical train. For this we attempted to track very small satellites. The first successful capture was UNICONRN-2N built by Alba Orbital (https://lnkd.in/eZvaB8BN) UNICORN-2N is a 3p Pocketcube, with the main body measuring 5x5x15cm with solar panels increasing the maximum surface area to roughly the size of a sheet of A4 paper. In the #KISENS project, intelligent optical sensors for space observation are being developed, which will be able to detect approaches and contribute to collision avoidance. Further Info can be found on https://lnkd.in/ezXu54GV The project is funded by the German Space Agency at the German Aerospace Center (DLR) with funds from the Federal Ministry for Economic Affairs and Climate Action (BMWK; FKZ 50RU2227) More tracking footage will follow in the next days!

I had just published this Analysys Mason article on the small GEO satellites manufacturing market when Astranis Space Technologies revealed their recent USD200 million funding round. This round is adding another layer to the dynamics and shifting demand in GEO satcom markets. As was seen by recent news from Airbus Defence and Space, building GEO with all kinds of bell and whistles is not easy. But packing high performance payloads into smaller form factors seems appealing for many satellite manufacturers going forward. 🔍 Key insights : - Small GEO orders will grow among the overall GEO orders. These are still few and far in-between but will remain a good part of the market revenues. - Shorter order-to-launch manufacturing timelines are the ‘new normal’. - New #launchers will help drive the business cases for operators of small GEOs. - Satellite operators' small GEO business cases will likely depend on how they can address new and expanding markets, such as government and military customers and regional operators. Bottom line:  Satellite manufacturers seeking market growth and new opportunities will enhance their value proposition with small GEOs. #Satellite #GEO #SmallGEO Dallas Kasaboski Dafni Christodoulopoulou Lockheed Martin Space Terran Orbital Corporation OHB SE SWISSto12

The space industry, a rapidly evolving frontier of technology and innovation, has expanded its scope beyond mere exploration to include telecommunications, Earth observation, and even commercial travel. This sector increasingly relies on advanced materials and technologies, among which fiber optics play a crucial role. Inertial navigation and attitude control are vital for direction finding and solar cell pointing on a range of space vehicles ranging from LEO, MEO and GEO satellites to planetary rovers. Fiber optic gyroscopes (FOGs) are one of the key enabling technologies, utilizing Fibercore’s HB-G polarization maintaining (PM) optical fibers at the heart of the gyro. For long duration or deep space missions, radiation tolerant variants are required. Fibercore’s range of Radiation Tolerant (RT) PM fibers fulfils this need. As the demands for faster data transmission and more reliable connections in space missions grow, the integration of fiber optics continues to propel the space industry into new realms of possibility and efficiency. Erbium Ytterbium doped TC1500Y(11/125)HD amplifier fiber is used within LEO satcom systems, enabling satellite-to-satellite and ground-to-satellite optical communications.

Satellite manufacturer Terran Orbital announced plans to produce a new line of small satellite buses designed to operate in geostationary Earth orbit. The company said it will compete in the so-called small GEO satellite market with a new bus named SmallSat GEO for satellites above 500 kg. Small GEO satellites are an emerging class of spacecraft designed for geostationary orbit 22,236 miles above Earth’s surface. This orbital perch has traditionally been the territory of large, heavyweight communications satellites that beam data to permanently pointed antennas on the ground. Small satellites typically have been deployed in low Earth orbit but are now being offered as a more flexible alternative for geostationary applications. They typically weigh in the range of 400 to 1,700 kg compared to tons for traditional GEO satellites. Commercial and military operators are exploring the use of small geosynchronous satellites to enhance communications networks. #TerranOrbital #SmallSatGEO #SATCOM Artist rendering of Terran Orbital’s SmallSat GEO.

The linked paper studies the #instability of self-driving #satellite mega-#constellations and its impacts on the network lifetime and capacity of Low Earth Orbit (#LEO) satellite internet #networks. The key findings are: Current automatic #collisionavoidance systems in self-driving mega-constellations, while excellent at avoiding collisions with external debris/satellites, can amplify internal collision risks via cascaded maneuvers between the constellation's own satellites. This causes a dilemma between the LEO network's long-term lifetime and short-term capacity. The root cause is that the decades-old local pairwise maneuver paradigm, where each satellite only responds to its most imminent collision risk, is inherently unstable when scaled to mega-constellations. A small maneuver by one satellite propagates and amplifies hop-by-hop through the constellation. The authors provide a control-theoretic analysis of this instability and empirically validate it using Starlink's space situational awareness data. STARLINK's maneuver policy is shown to be unstable, causing explosive growth of maneuvers that exhaust satellites' limited fuel and shorten the network lifetime. To stabilize maneuvers, inter-satellite spacing needs to be increased, fundamentally limiting the constellation's size and network capacity. The authors propose bilateral maneuver control that allows stable mega-constellation self-driving without limiting network capacity. By coordinating each satellite's response to both its leading and trailing satellites, cascading can be suppressed. In summary, the paper reveals an inherent architectural limitation of current collision avoidance approaches in self-driving mega-constellations, analyzes it theoretically and empirically, and proposes a new algorithm to enable stable and scalable satellite networks. The findings have important implications for the design of the growing number of planned LEO internet mega-constellations.
