GPS-Disciplined Frequency Standard

Suntsu Frequency Control, Inc. offers the SGPS2 series GPS- disciplined frequency and time standard. Combining a Furuno 16-channel GPS receiver and Suntsu’s own oven controlled crystal oscillator (OCXO) technology in a 2 x 2 x 1.25 inches (50.8 x 50.8 x 31.75 millimeters) package, the entire unit is mountable on printed circuit boards with a micro-miniature connector (MMCX) antenna connection on the side. The OCXO frequency is disciplined with timing signals from GPS satellites to maintain frequency accuracy to <1×10-12 in 24 hours.

The OCXO frequency is disciplined with timing signals from GPS satellites to maintain frequency accuracy to <1×10-12 in 24 hours. A new adaptive algorithm changes the control loop coefficients as environmental conditions change in order to maintain exact accuracy of the 1PPS to <20 nanoseconds, and holdover to <1 microseconds in 2 hours. In addition an alternative 1PPS input selected through the serial interface can be used in place of the GPS antenna input. Suntsu Frequency Control, Inc., Lake Forest, California, USA
