Brandywine’s miniature GPS Disciplined Oscillator combines the power of our existing disciplined oscillators in a footprint the size of an OCXO. Designed with interoperability in mind, the Miniature GPS Disciplined Oscillator meets military requirements such as MIL-STD-188-164A.  The GPSDO supplies a low noise, precision 10 MHz frequency reference signal output.  This output is accurate to 1x10-12 when slaved 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.  A serial data port is provided to report time, date, position, and GPS satellite health and signal strength.
 
Optional capabilities include automatic interface to an external military GPS receiver such as the Defense Advanced GPS Receiver (DAGR), Standard frequency output is 10 MHZ, but other frequencies are possible.
