GPSDO Taming Clock GPS Timing 10MHz Frequency Reference UCCM Module GPS Disciplined Oscillator with Power Supply and Antenna

GPSDO Taming Clock GPS Timing 10MHz Frequency Reference UCCM Module GPS Disciplined Oscillator with Power Supply and Antenna

Description:
- This GPSDO taming clock adopts for Samsung UCCM (Universal Center Clock Module) clock module, which has the characteristics of fast locking, high sensitivity, strong frequency stability, and low phase noise. It is very suitable for use as a clock source for high temperature HiFi audio devices or as a frequency reference for laboratories.
- The internal core is the secondhand UCCM module, which was originally integrated into high-end communication equipment after being dismantled. Due to equipment upgrades, the UCCM module has been dismantled and sold separately at a much lower price than the new product. Built-in STP2878 OCXO constant temperature crystal oscillator and uBlox LEA-6T GPS receiver module. Its comprehensive performance is as follows:
  * The average accuracy within 24 hours after GPS locking is 1x10^-12, equivalent to 10.00000000001MHz, with an accuracy of 0.000001ppm (0.001ppb).
  * When GPS is not connected, it can still maintain an accuracy of 1x10^-10
  * Phase noise: better than -100dBc at 1Hz offset
  * Allen variance: < 1e-12 at 1S

Connection and Monitoring:
- The UCCM module supports connection to a computer via RS232 serial port and can be monitored for status and parameter settings using terminal software or GPS monitoring software for Lady Heather. The information that can be viewed includes UTC time, satellite signal strength, PPS time quality, frequency quality, etc.

Usage Suggestion:
- Antenna location: ensure that the antenna can receive at least 50% of the sky signal, preferably installed in open areas (such as rooftops).
- Power on time: to improve frequency accuracy, it is recommended that GPSDO equipment be powered on for a long time.
- Audio usage: connect the GPS antenna for the first time and power it on for at least 24 hours, then disconnect the GPS antenna to continue using.
- Module status: although the UCCM module is a second-hand dismantled part, it has undergone comprehensive testing to ensure its normal performance.
