QuestionWhy is there a 1 second time error from my GPS reference?
AnswerJuly 20, 2016
We have identified a potential one-second error in the GPS-based time calculation in some of our products related to the pending Leap Second notification in the GPS message.
This timing error is affecting many GPS Systems from different manufacturers. The identified Spectracom products affected are those equipped with the Trimble Resolution SMT GG receiver or Accutime GG smart antenna:
- SecureSync/NetClock 9400 (serial number range 05006-11719 Manufactured between Nov 2013 and March 2016) [How do I determine the GPS receiver type in a SecureSync or NetClock 9400]
- TSync bus-level timing boards
- Epsilon Clock model EC20S
We are working directly with the Trimble engineering team on a resolution. Please contact us if you have an urgent need to correct the problem. Otherwise, we will be posting a permanent fix to the problem shortly. You can register your email address to be notified for the solution here.
The permanent fix is released and available for SecureSync/NetClock 9400 here.
