Orolia Introduces its First Low SWaP-C Miniaturized Rubidium Oscillator

World leader in Resilient Positioning, Navigation and Timing (PNT) solutions and space-based atomic clocks, Orolia, has introduced the Spectratime mRO-50. It is a breakthrough low SWaP-C (Size, Weight, Power and Cost) Miniaturized Rubidium Oscillator designed to meet the latest commercial, military and aerospace requirements where time stability and power consumption are critical.

The Spectratime mRO-50 provides a one day holdover below 1µs and a retrace below 1 x 10-10 in a form factor (50.8 x 50.8 x 19.5mm) that takes up only 51 cc of volume (about one-third of the volume compared to standard rubidium) and consumes only 0.45W of power, which is about ten times less than existing solutions with similar capabilities.

With these competitive advantages, the new Spectratime mRO-50 Miniaturized Rubidium Oscillator provides accurate frequency and precise time synchronization to mobile applications, such as military radio-pack systems in GNSS denied environments. Its improved operating temperature of-10°C to 60°C (military version extended to -40°C to 75°C) is also ideal for UAVs and underwater applications.

Orolia’s Atomic Clocks team received the 2019 PTTI Distinguished Service Award in January 2020 for advancing the state-of-the-art in high stability atomic clocks and producing the only space-based passive H-maser in the world, operating on all Galileo satellites. Spectratime mRO-50 is the latest technology solution offered through this award-winning team.
