Instruction Book for Time Standard AN/FSM-5A
Abstract
To isolate and eliminate the various causes of errors in the determination and distribution of Navy time signals, the Naval Research Laboratory has been carrying out theoretical and experimental investigations of techniques useful in the precise determination of standard time and time intervals including the evaluation of their relative merits. The basic techniques in the AN/FSM-5A equipments were developed at NRL to provide a means of evaluating and resolving various errors in the present Navy time system. The equipment contains a 100-kc oscillator, a five channel electronic keyer with fixed program sequence, and a measuring system for rapidly comparing and setting the equipment to the Naval Observatory time signals as transmitted by radio or landline. The oscillator is capable of maintaining a constant rate of better than one part in 10^8. The measuring system resolution is better than one millisecond.
