GPStarplus Model 565

 
 


GPStarplus is a fully featured, off-the-shelf, compact time and frequency system providing a new level of price/performance. It provides accuracy within 100 nanoseconds of
UTC (Coordinated Universal Time). GPStarplus tracks up to eight satellites at a time. When used as a frequency standard, GPStarplus can provide 5 E-12 frequency accuracy.

GPStarplus is packaged in a 19" rack mount chassis that is only 1.75" high. The control
and operation interface is provided via RS-232 or a front panel key pad. A 2-line by 40-character backlit LCD display reports Julian time and date, as well as informing the user if
time is locked, how many satellites are being received, and other status information.
The standard power supply operates from 95 - 264 VAC at 50 - 60 Hz.
