Epsilon Clocks and Ageless® master oscillators are highly accurate frequency and timing sources locked to GPS. Both Rubidium and oven-stabilized crystal (OCXO) oscillators are available depending on the allowable drift in event of loss of GPS. GPS clocks and master oscillators are ideally suited as a site master clock / oscillator for communication systems for for test and measurement applications. Typical uses include calibration, digital broadcast, land mobile simulcast, narrow band land mobile radio, SMR (specialized mobile radio), paging simulcast, satellite/microwave communication links, T1/E1, cellular telephone, and SDH/SONET and ATM enterprise timing.
