  • Orolia’s latest offering comes with improved features such as low power consumption and wide temperature range
  • Provides accurate frequency and precise time synchronization to mobile applications

Orolia, a provider of Resilient Positioning, Navigation and Timing (PNT) solutions and space-based atomic clocks, has introduced a breakthrough low SWaP-C Miniaturized Rubidium Oscillator, the Spectratime mRO-50, for meeting the latest commercial, military and aerospace requirements where time stability and power consumption are critical factors.

The Spectratime mRO-50 provides a one day holdover below 1µs and a retrace below 1E-10 that takes up only 51 cc of volume (about one-third of the volume compared to standard rubidiums) and consumes only 0.45W of power, which is about ten times less than existing solutions with similar capabilities.

With these advantageous features, the Miniaturized Rubidium Oscillator provides accurate frequency and precise time synchronization to mobile applications, such as military radio-pack systems in environments without GNSS. Its operating temperature of -10 degrees Celsius to 60 degrees Celsius (military version having -40 degrees Celsius to 75 degrees Celsius) is ideal for UAVs and underwater applications.

“Through Orolia’s continuous commitment to innovation, we are proud to offer our customers more precise PNT data in a cutting-edge, lightweight form factor for mobile missions,” said Orolia’s Atomic Clocks Product Line Director, Jean-Charles Chen.

The Spectratime mRO-50 is available in a form factor of 50.8mm x 50.8mm x 19.5mm.

The company also provides testing instruments for space missions that rely on high precision atomic clock technology.
