mRO-50 Rubidium Oscillator: Frequency & Stability
The mRO-50 is a rubidium oscillator designed to generate a 10MHz frequency to systems that require stable frequency.
Compared to other rubidium oscillators, the mRO-50 is a miniature version that is small enough to fit in the palm of your hand. It is the lowest SWaP solution in our atomic clocks and oscillators portfolio measuring fifty millimeters length and width and twenty millimeters height. The mRO-50 allows you to maintain resilient navigation and communication, even in GPS denied environments by providing an ultra stable frequency source your system will continue to have precise time and navigation even if there is no GPS signal or if it is jammed. For your accurate timing requirements, the mRO-50 atomic clock provides you with incredible frequency stability. It has a one day holdover performance below one microsecond.
You could go an entire day without a GPS or satellite signal and still maintain precise time accuracy. Because of its internal design, it uses the microwave optical double resonance technique. The mRO-50 has less electronics inside the enclosure compared to other clocks of this size. And thus fewer points of failure. The mRO-50 only consumes point five watts of power, which translates to increased mission duration. If you're using equipment that has limited battery life, you can depend on the power efficiency of the mRO-50 to last through even the longest of missions. Safran has also developed a ruggedized version of the mRO-50 designed for mobile use cases and harsh environments.
It can operate reliably in freezing condition. Minus forty degrees Celsius, as well as extremely hot environments up to eighty degrees Celsius.
The vibration resistant capacity of the mRO-50 meets or exceeds military standards, allowing the mRO-50 to endure 50 gs of force and 7 GRMS of vibration.
This means it can be used on aircrafts, UAVs, ground transports going over bumps, or any fast moving vehicle.
What are some of the real world use cases of the mRO-50?
The mRO-50 has been successfully used in defense applications and RF communication systems.
In the event of a jamming or spoofing attack, the mRO-50 acts as a resilient backup time source for radio systems equipped imRO-50 does not rely on satellite signals to receive timing information, you're less vulnerable to interference.
Similarly, a mRO-50 used on both ends of a radio communication will provide tight synchronization between the transmitting and receiving radio. This synchronization allows the communication system to utilize very fast frequency hop rates. Or in the case of UAVs and aircraft, the mRO-50 can provide a reliable ten megahertz frequency to the navigation system. Again, because the mRO-50 is independent of GNSS signals, it can continue to produce an accurate timing source for your navigation equipment, even if you lose a lock with satellite signals.
The mRO-50 has been designed to generate a stable ten MHz signal in a GNSS degraded environment such as tunnels, urban canyons, or bridges. If there is interference from jamming or spoofing, your system can continue to operate the whole time, uninterrupted by the loss of satellite signals.
The mRO-50 is also used in key commercial applications. In data centers and networks, the mRO-50 has been used to provide a backup timing source to ensure resiliency.
Integrating the rubidium oscillator into each node, the network can stay synchronized with high accuracy.
In the event of an interruption of the primary timing source, the rubidium oscillator is able to provide a stable frequency source that ensures the network maintains accurate timekeeping.
