🚀 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!
