Currently, FTS is constructing five advanced Preproduction Models (Model FTS 4402) as well as manufacturing the full GPS Block II complement of 56 advanced Space Vehicle Clocks (Model FTS 4401A). The design and applications history of these clocks is depicted in Fig. 1 and Tables 1 and 2. The basic design concept of these clocks which include a digital integrator featuring an infinite loop-time constant is depicted in the general block diagram of Fig. 2 and the detailed servo/integrator subsystem in Fig. 3.
