High-Performance Rubidium Atomic Clocks

Safran Rubidium Atomic Clocks are made with the microwave optical double resonance (MODR) technique, providing you with a low SWaP-C solution in a small form factor. It’s 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 500 ns in a form factor (50.8 x 50.8 x 16mm) that takes up only 42 cc of volume (about one-third of the volume compared to standard rubidiums) and consumes only 0.5W of power in the steady state function (it consumes 1.5W of power using the high performance function), which is about ten times less than existing solutions with similar capabilities.

Since Safran’s atomic clocks are ruggedized, they are able to provide accurate frequency and precise atomic time synchronization to mobile applications, such as military radio-pack systems in GNSS-degraded or denied environments. Its wide-ranging operating temperature of -40° to +80°C is also ideal for Underwater, Military, Radars, Low Earth Orbit, Electronic Warfare, Airbornes & Avionics, and UAV/UGV/USV/UUV.
