Atomic Frequency Standards for the GPS IIF Satellites

Abstract

The GPS IIF block of satellites will carry Cs beam and Rb vapor cell atomic frequency standards. This paper presents a description of the two frequency standards and reviews their expected performance. The performance of the two technologies is also assessed within the context of the orbital environment. User range error, a measure of accuracy, is calculated based on projected performance of the IIF frequency standards. Potential system performance improvements, possible with two future clock technologies, are also considered.
