Safran GAHM Ground Active Hydrogen Maser

The Ground Active Hydrogen Maser (GAHM) is Safran’s new proprietary frequency stability atomic clock. Designed for Ground Segment Space Applications (deep space tracking, geodesy, radioastronomy, …), GNSS Precise Time Stations, Autonomous time scale for defense and security, and, for National Metrology Institute to build the International atomic time (TAI) mandatory for UTC time.

The GAHM is backed by Safran’s successful 40-years track record of manufacturing high performance atomic clocks and fielding 200 units worldwide in High-level operational sites (extreme environmental sites, high level of maintainability).

ADVANTAGES

Atomic Clock Design Experience

Safran has over 40 years of experience developing, testing, and refining the most precise oscillators and atomic clocks in the world. Whether it’s rubidium or cesium, Safran has embraced the technical challenges of precise timekeeping and the rigorous scientific experimentation to bolster the products.

Stabile Lifetime

When you acquire the Ground Active Hydrogen Maser, you can rest assured that it will last for over 20 years. This includes a maintenance-free package. It is that simple. It has been designed to stand the test of time.Reliable, Stable Frequency – with a Frequency Stability @ 1s: <1.5E-13 / @1d: <2.5E-15, the GAHM provides cutting-edge accuracy and precision and a frequency output that you can depend on.
