The GPSDO from Brandywine Communications is a small Off-the-Shelf (COTS) GPSDisciplined Oscillator that has been designed to meet military requirements and is MIL-STD-188-164A certified. This GPSDO supplies three isolated, low noise precision 10 MHz frequency reference signal outputs. These outputs are accurate to 1x10-12 when a slave to a GPS source. The frequency standard is also able to slave to an external 1PPS signal to steer and hold the internal oscillator and clock system precisely in time. Time and frequency information maintains its high accuracy with the internal oscillator even when no satellites can be tracked. It is available in a surface-mount package that measures 4.1 x 2.75 1 inches. A serial data port is provided to report time, date, position, and GPS satellite health and signal strength.
