A rubidium standard, often known as an atomic clock made of rubidium, is a type of frequency standard in which the output frequency is controlled by a specific hyperfine transition of the electrons in rubidium-87 atoms.
The simplest and smallest of all atomic clocks, rubidium atomic clocks use a glass cell of rubidium gas that, when the surrounding microwave frequency is exactly perfect, changes its absorption of light at the optical rubidium frequency.
The global rubidium atomic clock market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In order to meet the most recent military and aerospace requirements where time stability and power consumption are crucial, Orolia, the global leader in resilient positioning, navigation, and timing (PNT) solutions and space-based atomic clocks, has introduced an upgraded edition of its low SWaP-C miniaturized rubidium atomic clock oscillator product line, the mRO-50 Ruggedized.
The mRO-50 Ruggedized offers a one-day holdover below 1s and a retrace below 1E-10 in a form factor (50.8 x 50.8 x 20mm) that uses just 51 cc of volume (roughly one-third of the volume compared to standard rubidiums) and only 0.36W of power, which is roughly ten times less than competing solutions with similar capabilities.
The new mRO-50 Ruggedized tiny rubidium atomic clock oscillator offers accurate frequency and exact time synchronization to transportable applications, such as military radio-pack systems in GNSS-degraded or prohibited settings, thanks to these competitive advantages.
Its wide operating temperature range of -40°C to 80°C makes it perfect for a variety of applications, including airborne, underwater, radar, low earth orbit, electronic warfare, and autonomous vehicles.
