mRO-50 Ruggedized Rubidium Atomic Clock

The mRO-50 Ruggedized is a breakthrough rb clock with microwave optical double resonance (MODR) low SWaP-C Miniaturized Rubidium Oscillator. It’s designed to meet the latest commercial, military and aerospace requirements where time stability and power consumption are critical. It provides a one day holdover below 1µs and a retrace below 1E-10 in a form factor (50.8 x 50.8 x 20mm) that takes up only 51 cc of volume (about one-third of the volume compared to standard rubidiums) and consumes only 0.36W of power, which is about ten times less than existing solutions with similar capabilities.

The mRO-50 Ruggedized Rubidium Oscillator provides accurate frequency and precise atomic time synchronization to mobile applications, such as military radio-pack systems in GNSS-degraded or denied environments. Its wide-ranging operating temperature of -40° to +80°C is also ideal for Underwater, Military, Radars, Low Earth Orbit, Electronic Warfare, Airbornes & Avionics, and UAVUnmanned Aerial Vehicle. Remotely piloted aircraft commonly referred to as a drone. See also/UGV/USV/UUV.
