Contact Support Spectratime mRO-50 Manual


The mRO-50 Ruggedized is a breakthrough microwave optical double resonance (MODR) 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 1E-10 in a form factor (50.8 x 50.8 x 20mm) that takes up only 51 cc of volume (about one-third of the volume compared to standard rubidiums) and consumes only 0.36W of power, which is about ten times less than existing solutions with similar capabilities.

The mRO-50 Ruggedized Oscillator provides accurate frequency and precise 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 Applications,
  • Military Communications,
  • Radars,
  • Low Earth Orbit,
  • Electronic Warfare,
  • Airbornes & Avionics,
  • UAV/UGV/USV/UUV
