z200 brochure

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.
