mRO-50 Atomic Clock
Miniature, Low SWaP-C Atomic Frequency Source
The mRO-50 Rubidium Atomic Clock is a breakthrough low SWaP-C Miniaturized Rubidium Oscillator 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 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 rubidiums) and consumes only 0.45W of power, or about ten times less than existing solutions with similar capabilities.
The mRO-50 provides accurate frequency and precise time synchronization to mobile applications, such as military radio-pack systems in GNSS denied environments. Its wide-ranging operating temperature of -40°C to +80°C is ideal for applications in extreme environments.
What is SWaP-C?
Size, Weight, Power and Cost.
Multiplied together, they produce a number that limits the possible use cases the higher it is, particularly in application areas where these factors count:
- When payload is measured to the gram
- When you don’t have an inch to space
- When power needs to be conserved
- When cost is critical
The mRO-50 is Swiss Made and designed and manufactured by Safran.
