🚀 HPS: Flagship CIMR-LDRS Project Reaches CDR Milestone!
On 12 October 2026, the Critical Design Review (CDR) for the Large Deployable Reflector Subsystem (LDRS) of ESA/EU’s Copernicus CIMR mission was successfully completed!

🛰 In parallel, the CIMR Satellite SYSTEM CDR officially kicked off at ESA/ESTEC on 30 September 2026, bringing together 75 key representatives from ESA and industry (see photo), including TAS-I, OHB-IT and HPS/LSS.

📡 HPS leads the LDRS Phase B2/C/D since December 2020, as prime contractor to Thales Alenia Space Italia (TAS-I).
Our partner LSS is responsible for the deployable reflector assembly.

🔧 An ambitious European space subsystem, a global FIRST:
The rotating LDRS comprises an 8-metre deployable arm, 8-metre reflector, thermal hardware, deployment control electronics, several hold-down and release mechanisms (HDRMs) and harness.

Three units are planned: an Engineering Qualification Model (EQM), a Proto-Flight Model and a second Flight Model. The EQM is already in manufacturing and assembly, with initial functional and vibration tests successfully completed. ✅

🌍 A European industrial effort
Our team includes partners from Germany (INVENT, vH&S, HPtex, Glenair, KRP, IABG, FEV etamax), Switzerland (NanoSpace), Portugal (FHP, INEGI), Sweden (LUMA), Romania (HPS-RO), Denmark (TICRA) and the Czech Republic (GL Electronics), among others.

💬 HPS CEO Dr. Ernst K. Pfeiffer:
“The successful completion of the LDRS-CDR is the result of intense work by each and every one of our own team and our subcontractors. The past months were defined by close coordination, extensive documentation, and AIT, purely stress. We thank all partners in the European industrial team for their contribution and our customer chain for their unbreakable trust in our capabilities.”

🌎 A flagship for European space:
With a contract value of more than €120 million, CIMR demonstrates HPS’ ability to lead large, technically demanding subsystems. The mission is considered a technological first in Earth observation, reinforcing ESA/EU’s position at the forefront of the field.

Pfeiffer adds: “The Copernicus joint programme is a proven success story—also on supplier-level, Europe’s SME and mid-sized business sector.” He hopes Copernicus and Earth observation will remain flagship initiatives for Europe’s space ambitions as key decisions are made at the ESA-IMM in December 2026 and the next ESA Ministerial Conference in 2028.

📡 LDRS beyond institutional space:
LDRS technology is also gaining importance in European commercial space. In spring 2026, HPS/LSS signed a contract with Swissto12 to develop and build a 5-metre L-band LDRS for the commercial broadband mission NEASTAR-1.

🤝 Congratulations and thanks to our teams, partners and customers for their commitment and trust!

🚀 HPS Takes Stage at IAC 2026 in Antalya 🇹🇷

The 77th International Astronautical Congress (IAC) in Antalya from 5 to 9 October brought together the “who’s who” of the international space sector. With a dedicated showcase and a clear IAC-focus on commercial space, HPS presented technologies and products from our Munich headquarters, HPS Romania in Bucharest and HPTex GmbH.

🛰️ Our technologies at IAC:
Led by HPS CEO Ernst K. Pfeiffer, our 4-person team showcased:
• oir ADEO deorbit dragsail modules
• Antenna subsystems & deployables
• High-precision metal mesh
• Thermal hardware
• MGSE.

🤝 High-level visitors and valuable discussions:
Our booth welcomed numerous distinguished visitors from the European space sector, including BMFTR State Secretary Launert, . Walther Pelzer, Head of the German Space Agency at DLR, ESA Director General Dr. Aschbacher, as well as ESA Directors Cheli for Earth Observation, Neuenschwander for Exploration and Densing for Operations & Space Safety.
We also welcomed Leonardo Director Comparini, OHB Executive Board member von der Recke and former ESA Director Morel, who has long emphasised the important role of European SMEs in space technology.
Discussions with Rossner, Head of the Earth Observation Department at the German Space Agency, focused in particular on CIMR and further Earth Observation topics.

🌍 Strong international interest:
IAC 2026 gave us the opportunity to deepen established partnerships within the European and ESA environment while also establishing promising new business contacts beyond Europe.
Particularly valuable were discussions with companies from Türkiye, India, Singapore, South Korea, Japan, the UAE, Brazil and South Africa. Our focus at the congress was clearly on commercial space and international business opportunities, rather than defence.

🇩🇪 Part of the German Pavilion:
HPS was proud to be part of the German Pavilion, supported by the Federal Ministry for Economic Affairs and Energy (BMWE). Our neighbouring exhibitors included OHB, TESAT, ArianeGroup, Exolaunch, Dcubed, DSI or IABG.
We would like to thank the German Aerospace Industries Association (BDLI), led by -Christine von Hahn, for organising the pavilion and the BMWE for its valuable support.

🤖 When space meets fashion:
A particular eye-catcher at the ESA booth was the humanoid robot AMECA, presented by our cooperation partner and fashion designer Theiss. AMECA wore a haute couture dress created from offcuts of HPS multilayer insulation material. An unusual and creative application that gave space materials a completely new visibility and demonstrated how technology can find inspiration far beyond its traditional environment.

🌱 Sustainability and the future of space:
The congress programme itself also provided valuable insights into the topics shaping the global space sector. One highlight was a SpaceX presentation on Starlink’s sustainability concept, highlighting the risks posed by active satellites whose operators do not share collision-avoidance information, as well as failed satellites that remain uncontrolled in orbit for years.

💬 HPS CEO Ernst K. Pfeiffer sums up:
“IAC 2026 provided us with an ideal platform to deepen our cooperation with close and trusted business partners within the ESA-environment, exchange important updates, establish promising new contacts outside Europe and gain a first-hand impression of the topics and developments shaping the global space sector.” 🚀

🍻 HPS Wiesn Day 2026 🎉
It’s always great to realise on that occasion our Team to Trust growing year after year. What started with just a half table in 2003 has now grown to seven fully occupied tables (plus corridor 🙈) at this year’s HPS Wiesn Day! 🍺

And even more special: 20 colleagues joined our Munich tradition for the very first time this year. A tradition we have been celebrating for many years and that keeps getting better as our team grows.

🤝 With our offices now spread across three floors, the Wiesn is also a great opportunity to bring colleagues together who might not see each other every day. Sitting together, in the "Löwenbräu" Tent, a perfect way to connect beyond the office. And let’s be honest: eating, drinking, standing on the benches, singing together and celebrating the Wiesn atmosphere is also a pretty good way to get to know your colleagues! 😃🥨🎶🍻

👗 One thing we particularly love seeing is how many colleagues embrace the tradition and come dressed in Tracht (rate >50%?): Lederhosen, Dirndl and plenty of good spirit made the Wiesn Day feel truly Bavarian. 😊

We are very happy to keep this tradition alive and to introduce more and more members of our Team to Trust to our beloved Munich Oktoberfest every year. ❤️

And of course, the evening didn’t end there… 🍻 A few colleagues continued the celebrations later at the Ochsenbraterei for a couple more beers and a Wiesn finale...no details... 😉

Prost from Munich! 🍺🥨

🚀 NEASTAR-1: 5-metre Deployable Reflector Reaches PDR Close-Out.

At the end of August, HPS/LSS successfully completed the Preliminary Design Review (PDR) close-out for the 5-metre Large Deployable Reflector Subsystem (LDRS) for the NEASTAR-1 mission.

The milestone was reached just four months after signing the Phase B/C/D contract, following an initial pre-development phase. It is an important step forward for the programme and reflects the focused ex*****on, close cooperation and steady progress of all teams involved.

🤝 Strong collaboration across the programme:
We would like to thank our direct customer and NEASTAR-1 mission prime SWISSto12 for the constructive collaboration and guidance throughout the programme. A shared focus on programme needs, including accommodation and interface definitions, timely decision-making, efficient documentation and streamlined reviews, supported very much the teams to reach this milestone.

🛰️ A 5-metre L-band deployable subsystem:
The LDRS is being developed for a commercial satcom mission in geostationary orbit. The subsystem includes the deployable arm, deployable reflector, hold-down and release mechanisms, harness and thermal hardware. MAIT activities are supported by tailored MGSE.

The HPS/LSS consortium is backed by an established supply chain across Germany, Switzerland, Portugal, Romania and the Czech Republic. ESA’s Directorate of Commercialisation is contributing to the GEO-orbit LDRS with financial support from Member States, mainly Germany, Switzerland and Portugal.

The antenna will be integrated onto SWISSto12’s HummingSat platform, a new class of geostationary satellite currently being manufactured for several global operators. Astrum Space is the end customer and will operate the satellite above Asia to provide dedicated direct-to-device connectivity.

💬 HPS CEO Ernst K. Pfeiffer:
“This cooperation demonstrates the value of trust, technical focus and shared commitment. The dedication of the LDRS project teams and their team leads at HPS GmbH and LSS GmbH has been essential to reaching this stage. I am very proud of what the teams have achieved.”

SWISSto12 CEO Emile de Rijk added:
“The successful completion of the PDR shortly after contract signature demonstrates that faster schedules can be achieved when small and capable teams work in an integrated fashion with a common goal, high ownership and dedication. We appreciate the performance of HPS/LSS as an effective partner, with a focus on delivering a performing product at speed.”

Erfolgreiche HPS/Fraunhofer-Zusammenarbeit bei Array-Antennen: Projekt MANT erreicht Halbzeit.‼️

Die HPS GmbH und das Fraunhofer IIS setzen ihre erfolgreiche Zusammenarbeit im Bereich innovativer Raumfahrtantennen konsequent fort: Im ESA-geförderten GSTP-Projekt MANT – „Miniaturised Deployable Antenna for Small and Nano Satellites“ – entwickelt das gemeinsame Team eine kompakte, entfaltbare Array-Antenne für Klein- und Nanosatelliten. Das Projekt, das HPS und Fraunhofer IIS Anfang 2025 gewinnen konnten, befindet sich nun zur Halbzeit und kurz vor dem Preliminary Design Review (PDR) im September 2026.

Im Mittelpunkt steht die Miniaturisierung eines Reflectarrays für Anwendungen im Ka-Band. Das Fraunhofer IIS bringt dabei seine Forschungs- und Entwicklungskompetenz in kompakten, leistungsfähigen Antennentechnologien ein, während HPS seine langjährige Erfahrung mit entfaltbaren, mechatronischen Raumfahrtstrukturen und Antennensystemen beisteuert. Ziel ist eine Antennenlösung, die im verstauten Zustand in weniger als 1U – also in einen Bauraum von rund 10 x 10 x 10 Kubikzentimetern – passt und sich damit besonders für CubeSat-Implementierungen bis maximal 16U eignet.

„MANT zeigt beispielhaft, wie die Zusammenarbeit zwischen Forschung und Industrie in der Raumfahrt funktioniert: wissenschaftliche Exzellenz, industrielle Umsetzungsstärke und ein gemeinsames Ziel, neue Technologien schneller in die Anwendung zu bringen“, so die Quintessenz eines aktuellen Austauschs zwischen HPS-CEO Ernst K. Pfeiffer und Fraunhofer IIS-Abteilungsleiter Rainer Wansch.

Mit MANT leisten HPS und Fraunhofer IIS einen wichtigen Beitrag zur nächsten Generation kleiner Satellitenplattformen: kompakter, leistungsfähiger und besser geeignet für moderne Erdbeobachtungs- und Kommunikationsanwendungen im Orbit.

Auf dieser Basis planen HPS und Fraunhofer IIS nun auch eine vertiefte Zusammenarbeit im Bereich Active Array Antennen. Vorgesehen ist der Einstieg von HPS im Rahmen eines laufenden ESA-ARTES-Projekts im Oktober 2026. Damit wird die erfolgreiche Partnerschaft in einem weiteren technologisch anspruchsvollen Feld fortgesetzt.

Die Kooperation zwischen HPS und der Fraunhofer-Gesellschaft besteht bereits seit mehr als zehn Jahren und umfasst unterschiedlichste Technologien. Eine besondere Verbindung mit dem Fraunhofer IIS besteht zudem über die deutsche Heinrich-Hertz-Mission: Beide Partner fliegen dort – unabhängig voneinander, aber auf demselben Satelliten – eigene Hardware.

☀️ Work hard. Hike together. Grow stronger. 🏔️
Yesterday, friday, july 24th, we swapped our desks for the mountains and spent an unforgettable HPS Team Day in the beautiful mountains near Lake Achensee.

After taking the cable car up the mountain, we kicked off the day with a quick breakfast at 1.850m, before half of the team set off on the two-hour hike to the Rofan Spitze (2.259m). 💪 It didn't matter who was an experienced hiker and who wasn't. We encouraged each other, reached the summit together and enjoyed the marvellous 360° view.

Others explored the hiking trails at their own pace, relaxed in the sunshine or enjoyed the breathtaking views. No matter which route everyone chose, the day was filled with great conversations, good food and drinks, and lots of laughter :) 🌄

One fun surprise made the day even more special: 41 people had signed up... but 47 colleagues showed up! 😄

To round off the day, we all came together again for a delicious lunch at Almstüberl (1.840m) and a few Weißbier 🍽️🍻

Moments like these remind us that our greatest strength isn't just the work we do—it's the people we do it with. Taking time to connect, support one another is what makes our team the "TEAM TO TRUST" 🧡

A huge thank you to everyone who joined and made yesterday such a fantastic day! 🧡
