A rubidium standard or rubidium atomic clock is a frequency standard in which a specified hyperfine transition of electrons in rubidium -87 atoms is used to control the output frequency. [1]

Safran is a world leader in rubidium atomic clocks and oscillators, rubidium standards, maser, testing instrument technologies and more that rely on accurate atomic time.

Aug 22, 2024 · In a rubidium clock, a gas of rubidium atoms is trapped in a vapor cell — essentially, a small glass box. A laser puts the atoms into a particular energy state.

The Pulsed Optically Pumped Rubidium Atomic Frequency Standard (POPRAFS) clock technology employs a pulsed laser light source locked to an optical transition in a separate Rb vapor cell, to prepare the atoms and probe the atomic transitions.

The Miniature Atomic Clock (MAC) was launched in 2020, setting the standard as the top-performing rubidium oscillator in terms of size and power efficiency. Since then, thousands of MAC units have been deployed across the communications, test and measurement and aerospace and defense sectors.

Unseen and forgotten in this now-routine use of GPS are the atomic clocks. The propagation times of signals trav-eling 20 000 km from space to Earth are measured at the nanosecond level, and from those measurements, positions are calculated to …

The SRO-100 is a reliable and best selling atomic clock that can generate both a 10 MHz frequency as well as 1 PPS output. The SRO-100 can act as a backup time source inside a SecureSync Time Server. It makes the time and frequency reference systems more resilient in case of a loss of GPS.

Dec 6, 2023 · The clock uses a rubidium vapor lamp and a glass cell containing rubidium. A voltage-controlled oscillator excites the cell with a 6.8 GHz signal. Rubidium atoms can exist in three states.

AccuBeat is a world leader in Rubidium oscillators, Time Servers and GPS disciplined atomic clock products and solutions with anti GPS/GNSS spoofing capabilities

The two most widely used atomic clocks in recent years have been the cesium beam atomic clock and the rubidium clock. Such clocks have provided the accuracy necessary to test general relativity and to track variations in the frequencies of pulsars.
