More

The TRU is a state of the art, high-precision time/frequency standard capable of outputting five isolated IRIG Time of Day and 1PPS reference outputs. The TRU uses an internal GPS receiver to control a precision oscillator with accuracy up to 1 x 10-12 and excellent short term stability.

The TRU incorporates a high-sensitivity 12 channel SAASM GPS receiver, incorporating the latest advances in GPS anti-spoofing technology.

Dual Ethernet ports are used for both monitoring/control of the FRU using Simple Network Monitoring Protocol (SNMP) as well as providing Network Time Protocol (NTP) to clients.

A Brandywine supplied user application may also be used to provide a Graphical User Interface to the TRU.

The TRU is available is a number of configurations to support specific applications. A

Mobile Application version features a special vibration isolated oscillator that provides isolation of the reference source from portable generator induced phase noise. The High Performance version uses a rubidium oscillator.

A C/A code GPS receiver is available for non-military applications.
