Frequency Standards

Frequency Standards

Excelitas Technologies is the world leader in the design, development and manufacture of Rubidium Atomic Frequency Standards (RAFS), also known as Atomic Clocks, for space-borne applications. RAFS are the heart of Global Navigation Satellite Systems. Our time standards were developed specifically for Global Positioning System (GPS) applications where an extremely reliable atomic clock, combining exceptional frequency stability and low drift with negligible environmental sensitivity is needed. With more than 100 space-qualified atomic clocks delivered and 60 already in space, far exceeding any other company, we continue to innovate for future space programs and are confident that our 30 years of experience, dedicated design and manufacturing capabilities and facilities will serve to enhance GPS satellites for decades to come.
