U.S. ARMY PTTI FREQUENCY-CONTROL ACTIVITIES AND PLANS

John R. Vig

Abstract:	The primary mission of the Frequency Control and Timing Branch, ETD Laboratory, is to develop the oscillators and clocks needed by evolving Army communications, navigation, surveillance, identification-friend-or-foe (IFF) and electronic warfare (EW) systems. The main emphasis is on the development of small, low-power, high-precision quartz crystal oscillators. This paper summarizes the current (1986) in-house and contractual programs and the directions that future programs are expected to take. Army Needs: Surveillance, c3, navigation, IFF and EW systems currently under development require high-stability quartz crystal and atomic oscillators for use as (spread spectrum) system clocks and frequency standards. For many evolving systems, the commercially available oscillators lack the required long-term stability, vibration resistance, radiation hardness, small size, low power consumption, and fast warmup capabilities.
