Auto Survey
In automatic mode, the EPSILON CLOCK MODEL EC1S calculates the
position of the antenna and, after testing the result, imposes the position
on the internal GPS receiver. The receiver therefore functions in GPS 0D
reception mode: The EPSILON CLOCK MODEL EC1S is synchronized by
tracking at least one satellite.

Holdover
If the reference input signal is lost, the EPSILON CLOCK® maintains the
generation of information and of time and frequency signals.
Reliability
Concerns the positioning mode of the antenna. In automatic mode, the
EPSILON CLOCK® calculates the position of the antenna and, after
testing the result, imposes the reliable position on the internal GPS
receiver. The receiver therefore functions in GPS 0D reception mode. The
EPSILON CLOCK® is synchronized by following at least one satellite.
Frequency driver
Frequency signal generated by the built-in oscillator.
Reference input
Time and frequency source used by the EPSILON CLOCK®.
IERS
International Earth Rotation Service.
