The Atlas 1PPS from Bliley Technologies is a GPS Disciplined OCXO (GPSDO) that operates at 10 MHz. This GPSDO combines an OCXO with a GPS module to provide high precision frequency stability. It has a holdover stability of ±10 ppb and phase noise of -123 dBc/Hz @ 10 Hz. The GPSDO requires start up power of 0.25 W and steady state power of 0.35 W. It is available in a 41 x 36 mm package and is ideal for a wide range of GPS Disciplined applications like GPS Denied Network Synchronization, Low Probability of Intercept (LPI) and Low Probability of Detection (LPD) Communications, Assured Timing for Critical Infrastructure, Battlefield Networks, Autonomous and Semi-Autonomous System Timing and Weapon System Synchronization.
The Atlas GPS disciplined oscillator is a drop in replacement for the CSAC that offers an order of magnitude cost reduction while still providing high timing accuracy and low error in GPS denied environments.
