Suntsu Frequency Control, Inc. Unveils the Smallest Precision GPS Frequency Standard Available in the Industry

LAKE FOREST, CA--(Marketwire - June 11, 2008) - The SGPS2 Series disciplined frequency and time standard represents the latest advancements in GPS and OCXO technology.

Combining a 16 channel GPS receiver and Suntsu's own advanced OCXO technology in a 2"x2"x1.25" package, the entire unit is PCB mountable with an MMCX antenna connection on the side. This is the smallest precision GPS frequency standard available in the industry.

The OCXO frequency is disciplined with timing signals from the GPS satellites to maintain frequency accuracy to < .001ppb in 24 hours. A new Adaptive Algorithm changes the control loop coefficients as the environmental conditions change to maintain exact accuracy of the 1PPS to < 20ns, and holdover to < 1µs in 2 hours. In addition, an alternative 1PPS input selected through the serial interface can be used in place of the GPS antenna input. These features make the SGPS2 GPS disciplined OCXO unit ideal for applications like CDMA, E911, or anywhere GPS references are currently in use.
