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. |
