Time Devices
ZTI provides computer time synchronization devices based on GPS
that can ensure reliable accurate time on any machine under Windows,
Linux/Unix or others...
We provide industrial time synchronization devices for servers and
workstations.
Our timing products can synchronize a single PC or a complete
network of devices.

The
z200
module
is designed specifically for GPS synchronization
applications, and will automatically enter a Self Survey mode of operation on power
up. The Self Survey mode allows the receiver to continuously
calculate its geographic position for a period of 20 minutes
(the pps is valid during this period but its accuracy will
fluctuate relative to the positional error).
After the 20 minutes self
survey period, the
z200
module
will automatically calculate an average of the geographical
position and fix this value in the receiver firmware, which
allows the pps to be more accurately controlled,
even when only one
satellite
is being tracked.
If no satellite is tracked,
the pps is still delivered thanks to
Holdover
mode,
with a drift better than 100μs/hour at room temperature. Another feature of the
z200
module
is the ability to maintain a positional fix at extremely low
GPS signal strengths, and to track satellites down to levels
of -155dBm (-185dBw) which equates to signal strengths
typically seen deep inside buildings. This means that the
antenna does not need to be located externally, up a mast or
on the rooftop as is the norm. This considerably reduces the
cost and complexity of deployment in terms of antenna
cabling and the need for lightning strike protection and significantly reduces the costs
associated with maintenance.

zClock | High Precision Clock |
|
Main Applications: instrumentation, metrology and all very accurate measurements
Clock module with a very high degree of accuracy for use on PC parallel port (EPP mode).
The Real Time Clock (RTC) built into most machines is far from reliable and most RTCs drift considerably over time. Based on a high stability and ultra stable OCXO (Oven-Controlled Crystal Oscillator) with a fast warm up, the zClock product offers a very precise clock (0,27ppm) to PC applications in a small and compact packaging.
