European Engineering Consultancy Ltd (EECL) achieved a technical milestone on the ESA HydroGNSS climate mission, launched in November 2025 from Vandenberg Space Force Base, California. This mission, ESA's first Earth Observation Scout mission, employs twin satellites to analyze faint GNSS signals for climate monitoring.

EECL designed six ultra-low-noise microwave amplifiers critical for signal amplification. Initial in-orbit results indicate successful performance, with both satellites collecting Delay Doppler Maps. The amplifiers were rigorously tested in the U.K. to meet space standards, reinforcing EECL's expertise in microwave technology for space applications.
