Orolia Introduces New Atomic Clock for Military & Aerospace Operations

The 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 By DA Reporter / 22 Jun 2022

Orolia has introduced the mRO-50 Ruggedized, an upgraded edition of its low Size, Weight, Power and Cost (SWaP-C) miniaturized rubidium oscillator product line, designed 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 the company has said 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. 

With a wide-range operating temperature of -40°C to 80°C, the mRO-50 Ruggedized is designed for a range of applications such as underwater, military communications, radars, low earth orbit, electronic warfare, airborne and unmanned vehicles.

“Our dedication and innovative design have contributed to the most accurate GNSS systems in service today,” said Orolia’s Atomic Clocks Product Line Director, Jean-Charles Chen. 

The mRO-50 Ruggedized enhances the breakthrough technology of the mRO-50, launched in 2020, with modifications providing wider thermal range, quicker lock and higher stability. 

The European Space Agency (ESA) awarded Orolia two contracts to provide atomic clocks for the first 12 satellites for the Galileo Second Generation System (G2S). Each of the new G2S satellites (designed to provide unprecedented accuracy worldwide) will contain three Orolia Rubidium Atomic Frequency Standards (RAFS) and two Orolia atomic clock physics packages integrated with Leonardo’s Passive Hydrogen Masers (PHM).

In order to provide in-depth mRO-50 Ruggedized product details, applications and technical information, Orolia is hosting a Launch Webinar on 7 July, 2022.
