讨论了设计目标和方法;更重要的设计特点;信号参数和误差预算;以及在开发用于全球定位系统导航卫星的第二源铷频率标准方面的早期测试结果。实验板版本的RFS的测试表明，测得的时域稳定性是在目标规格。结果未对参比品的组成进行校正，可能受到中期区域内参比品稳定性的限制。Rb参考在中期区域较好，但Cs参考在10，000秒或更长时间较好，这可能是因为铷参考单位的气压灵敏度。
The design objectives and approach; the more important design features; the signal parameters and error budget; and early test results in the development of a second-source rubidium frequency standard for use in the GPS navigation satellites are discussed. Tests of a breadboard version of the RFS show that the measured time-domain stability is within the goal specification. The results are uncorrected for the conribution of the reference and are probably limited by the reference stability in the medium term region. The Rb reference is bbetter in the medium term region, but the Cs reference is etter at 10,000 seconds and longer, probably because of the barometric sensitivity of the rubidium reference unit.
