Cutting-edge technology innovations in RF, antennas & ground stations
OUR FACILITIES
Our headquarters in Santander (Spain) is over 4000m2 in size and has a specific mass-production area.
We have state of the art equipment and facilities that allow us to undertake any technological challenge.
Clean room
A certified ISO 7 clean room, also certified as an ESD Protected Area (EPA) according to the standard IEC-61340-5.1, for the integration and validation of RF products in controlled environmental conditions. Its size of 47 m2 can be adapted in accordance with the production needs of our qualified RF products for the space, aeronautics and defence sectors.
Bonding room
RF & MW laboratory
Anechoic chamber
A large anechoic chamber (11 x 6 x 5 m) with measurement capabilities up to 40 GHz. This chamber is equipped with the latest generation of control and post processing software, as well as automatic array calibration tools. Celestia TTI offers its customers the possibility of using the anechoic chamber, at a very competitive pay-per use price.
Production area
Celestia TTI can produce PCBs and mechanical pieces. The production equipment set includes: Pick & Place tools, PCB drilling equipment (LPKF PROTOMAT), ultrasound cleaning system and a mechanical workshop including (CNC) drilling machine. Celestia TTI has specific areas dedicated to component soldering and inspection.
Cryogenic laboratory
Celestia TTI has cryogenic testing and characterizing facilities, including reconfigurable laboratory cryostats up to 10 ºK (-263 ºC) with an automatic measurement system of scattering parameters and noise temperature.
Climate chamber
Celestia TTI has a set of climate chambers to test our equipment from -65 ºC to 150 ºC, with the possibility of managing large loads. We can test production batches simultaneously to the most demanding conditions to ensure reliability and full functionality over a wide range of temperatures.

Certifications & Quality Standards
Celestia TTI operates under the highest quality standards to ensure reliability and performance in every product and project we deliver.
ISO 9001:2015 Certified — Our quality management system covers the design, development, production and integration of telecommunications equipment, with multisite certification across all our locations.
ISO 7 Clean Room — A certified controlled environment for the integration and validation of RF products destined for space, aeronautics and defence applications, also certified as an ESD Protected Area (EPA) according to the IEC-61340-5.1 standard.
Space-Qualified Manufacturing — Our production processes and materials meet the stringent requirements of the European Space Agency (ESA) and other international space programmes, with flight-proven hardware delivered for multiple missions.
Environmental & Reliability Testing — In-house climate chambers (-65 to 150 degrees C), cryogenic laboratories (down to 10 K) and a large anechoic chamber (11 x 6 x 5 m, up to 40 GHz) enable comprehensive qualification and acceptance testing.
Proven Track Record with Leading Institutions
Over more than two decades, Celestia TTI has earned the trust of the world’s most demanding organisations in space, science and defence. Our engineering heritage spans hundreds of projects delivered to agencies, operators and research centres worldwide.
European Space Agency (ESA) — Celestia TTI is a long-standing ESA supplier. We designed and manufactured X/K-band coaxial feed systems deployed at ESA’s Deep Space Antenna network (DSA-2 Cebreros, Spain and DSA-3 Malargue, Argentina). We also delivered critical upgrades for the ESTRACK global tracking station network under the XATACA programme, improving X-band auto-tracking capabilities for LEO satellite operations.
Space Debris Tracking (EU-SST) — Celestia TTI leads the consortium developing Greece’s LEO Space Debris Tracking Radar (HSTR) as prime contractor, contributing to the European Space Surveillance and Tracking programme for orbital safety.
Broadcast & Teleports — Our GaN solid-state power amplifiers (SSPAs) are deployed in major teleport facilities and broadcast uplink stations worldwide, providing reliable high-power amplification for DTH, SNG and contribution services.
Radio Astronomy & Science — Celestia TTI designs and manufactures ultra-low-noise cryogenic amplifiers operating at temperatures as low as 10 K for radio astronomy observatories, enabling deep space communication and scientific discovery at the frontiers of physics.
