Rubidium oscillator for position, navigation, and timing (PNT) in GNSS-denied areas introduced by Orolia

Aug. 5, 2022
The PNT subsystem is for military underwater communications, radar, low-Earth orbit uses, electronic warfare (EW), aircraft, and unmanned vehicles.

WEST HENRIETTA, N.Y. – Orolia USA in West Henrietta, N.Y., is introducing the mRO-50 Rugged miniaturized rubidium oscillator for military and aerospace requirements where time stability and low power consumption are critical.

The subsystem is for GNSS-denied applications like military radio-pack systems, military underwater communications, radar, low-Earth orbit, electronic warfare (EW), aircraft, and unmanned vehicles.

The mRO-50 Ruggedized provides a one-day holdover below 1 microsecond and a retrace below 1E-10. The position, navigation, and timing (PNT) product measures 50.8 by 50.8 by 20 millimeters, and takes up 51 cubic centimeters of volume.

It consumes 0.36 Watts of power, which is about ten times less than existing solutions with similar capabilities, operates in temperatures from -40 to 80 degrees Celsius.

The miniaturized mRO-50 Ruggedized rubidium oscillator offers low size, weight, power consumption, and cost (SWaP-C), and provides accurate frequency and precise time synchronization in global navigation satellite system (GNSS)-denied and -degraded environments.

The mRO-50 Ruggedized provides wide thermal range, quick lock, and high stability. For more information contact Orolia online at
