摘要

ITT工业公司开发的GPS IIR卫星有效载荷自1997年7月以来一直在轨运行，提供了出色的空间信号性能。这一出色的表现在很大程度上要归功于GPS IIR计时系统(TKS)。TKS系统的一个关键组成部分是Perkin Elmer的铷原子频率标准(RAFS)。我们现在有超过40年的GPS IIR TKS和raf在轨经验。在本文中，我们提出了12个在轨工作频率标准的特点，其中8个是同族的，是GPS星座中表现最好的，尽管其中4个具有可检测的特征。本文深入分析了每一种在轨作战raf的独特特征

GPS block IIR clocks in space: current performance and plans for the future

ITT Industries developed GPS IIR satellite payloads have been on-orbit since July of 1997, providing outstanding signal-in-space performance. Much of the credit for this outstanding performance can be given to the GPS IIR time keeping system (TKS). A key component of the TKS system is Perkin Elmer's rubidium atomic frequency standard (RAFS). We now have over 40 years of on-orbit experience with the GPS IIR TKS and RAFS. In this paper, we present the characteristics of the twelve on-orbit operating frequency standards, eight of which are in family and are the best performers in the GPS constellation, although four of which exhibit detectable features. This paper provides insight into the unique characteristics of each on-orbit operational RAFS
