Hydrogen Maser Frequency Standard Systems Technology.

Abstract

Space-qualified hydrogen maser atomic clocks suitable for the Global Positioning System (GPS) are reviewed in this study. Existing ground-based masers are compared in performance and failure modes. Design improvements are suggested for the components of both the physics unit and the electronics unit of a space qualifiable maser clock. Several overall design options including passive operation are compared in projected performance. Reliability and accelerated life testing procedures are discussed. A schedule for the orderly development of masers for the GPS is given.
