NanoSync III™
Model 407
|
|
| |
The NanoSync III is a very compact
(2.25 inch x 4.0 inch x 8.0 inch), low power GPS referenced time
and frequency module providing a precise 1PPS and
10MHz reference in a small, ruggedized enclosure.
Well-suited
for various military platforms supporting wireless and
electronic warfare applications, the NanoSync III SAASM
comes equipped with either a GB-GRAM or MRU SAASM receiver,
easy-to-use key load connector, PLGR/DAGR port for hot start
GPS acquisition and a zeroize switch. NanoSync III is also
available with a civil C/A code GPS receiver.
In the event of GPS signal loss,
the NanoSync III will continue to provide accurate time and
frequency using a high stability crystal oscillator (OCXO).
The NanoSync III uses the latest FEI-Zyfer proprietary
learning algorithm to compensate for external and internal
conditions that may affect accuracy, ensuring
the most accurate GPS time and frequency reference available.
The NanoSync III can be monitored and controlled through an
easily accessible RS-232 port. |
