About TTI Norte

Celestia TTI (formerly TTI Norte) is a Spanish satellite ground systems company founded in 1996 in Santander, Cantabria, and now operating as a subsidiary of the Celestia Technologies Group, an international satellite ground segment conglomerate. With more than 25 years of experience and around 100 staff, the company holds ISO 9001:2015 and AS/EN 9100:2018 certifications.

The company designs and manufactures RF electronics and antenna systems for satellite ground stations and spaceborne platforms, including Solid-State Power Amplifiers (SSPAs), Block Upconverters (BUCs), Low-Noise Amplifiers (LNAs) and LNBs, cryogenic amplifiers for radio astronomy, phased array and flat-panel antennas, passive RF components (feeders, orthomode transducers, polarisers) and frequency converters.

Celestia TTI's products have been supplied to major European satellite programs including SpainSat NG I (UHF amplifiers, launched 2025), the ESA ESTRACK deep space antenna network (X/K-band cryogenic receiver upgrade, five-year contract from 2020), and the ESA Galileo navigation satellite program (phased array uplink station antenna, 2021). The company also supplies electronically-steered, no-moving-parts multi-beam antennas (MEGA) for MEOLUT Galileo Search & Rescue ground stations, and equipment for EU Space Surveillance and Tracking (SST) debris monitoring installations.

The facility in Santander operates a 4,000 square metre manufacturing and test centre with ISO 7 cleanroom capability, serving broadcast, aerospace, radio astronomy/deep space, particle accelerator, and government/defence markets.
