The LN Rubidium Reference builds upon, and is backwards compatible to our LN CSAC GPSDO product line. These Rubidium units have better Phase Noise, better ADEV performance, lower thermal sensitivity, better holdover performance, longer lifetime and MTBF, and lower cost than comparable units.
The AR51A05 incorporates numerous features into a single box, including a Rubidium Standard, an internal GPS receiver a RubidiumGPS DPLL (disciplining) circuit, time codes, multiple outputs. The Rubidium clock is phase locked to the GPS or other external inputs (as a backup to GPS system).
When the frequency of the applied rf signal corresponds to the frequency of the groundstate hyperfine transition of the 87Rb atom (an ultrastable highQ rubidium atomic resonance), light is absorbed causing a change (decrease) in photo detector current (IPH).
an Ovenized Quartz or a Rubidium Atomic oscillator, as well as Civil or Military (SAASM) GPS receiver options. In addition, the GSync II can receive external inputs to provide internal frequency synchronization to the accuracy of the external source.
A rubidium standard, or rubidium atomic clock, is a high accuracy frequency and time standard, usually accurate to within a few parts in 10 11.This is still several orders of magnitude less than
Development of the Fast Warmup Rubidium Atomic Oscillator A design method and experiment data for fast warmup Rubidium Atomic Oscillator are introduced in

As for the receiver using atomic clocks, CSAC and a rubidium frequency standard in our analysis, the PLL bandwidth can be reduced down to at least 0.1 Hz while C/N 0 is above 15 dBHz. Experimental Tracking Loop Performance. Experimental data
solution is the Rubidium Atomic Reference. A rubidium oscillator will provide better shortterm stability and frequency accuracy, which becomes important for signal integrity and cochannel interference. Phase noise, that relates to jitter in the digital world, is much better than a standard GPS receiver. Rubidium also offers a low aging rate of
Study of the Stark Shift of New Type Rubidium Atomic Optical Filter Because of very narrow passband and very high outofband suppression of the Na atomic optical filter,the lidar echo at 80～110 km altitude can
Note 1: The accuracy in Hertz is based on the standard frequency of 10 MHz. For example: Accuracy of TCXO (free run one day) is ۫𬭃 䞆MHz = ± 1 HZ . The given values for the accuracy of frequency and time (not short term accuracy) are only valid for a constant ambient temperature !
It utilizes a GPS disciplined rubidium frequency reference to provide timing outputs characterized by the shortterm stability of the atomic reference and the longterm stability of GPS. The versatility of the TSC 4420A makes it suitable for a variety of appliions.
Enhancing the positioning precision is the primary pursuit of global positioning system (GPS) users. To achieve this goal, most studies have focused on the relationship between GPS receiver clock
Q: GPS satellites used to carry two cesium and two rubidium atomic standards on board. Subsequently, GPS switched to all rubidium clocks. Galileo plans to use hydrogen masers instead. What are the relative merits of these clocks for use in navigation satellites? A: It is well recognized that the spacequalified atomic clocks in the GPS satellites are an enabling technology, if not the enabling
PHYS 450 Design Project Final Report: Rubidium Atomic Clock Josh Bendavid 4920047 David Burns 4920860 Although the overall objective of the project is to build a functioning Rubidium atomic frequency standard, and to characterize its performance, doing so requires many subcomponents, each with their own set of receiver we acquired
An atomic clock is a clock device that uses a hyperfine transition frequency in the microwave, or electron transition frequency in the optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are
