Orolia, the world leader in resilient positioning, navigation and timing (PNT) solutions and space-based atomic clocks, has introduced an upgraded edition of its low SWaP-C miniaturized rubidium oscillator product line, the mRO-50 Ruggedized, to meet the latest military and aerospace requirements where time stability and power consumption are critical.

The mRO-50 Ruggedized 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.

With these competitive advantages, the new mRO-50 Ruggedized miniaturized rubidium oscillator provides accurate frequency and precise time synchronization to mobile applications, such as military radio-pack systems in GNSS-degraded or denied environments. Its wide-range operating temperature of -40°C to 80°C is also ideal for various range of applications such as underwater, military communications, radars, low earth orbit, electronic warfare, airborne and unmanned vehicles.
