![]() The atomic clock has a built-in RCC receiver for automatic synchronization of WWVB radio broadcasts. It is expected that the signal can reach a distance of over 2,000 miles from the transmitter.The NIST broadcasts the time signal (WWVB,60KHz) continuously from Fort Collins, Colorado. They can receive the time signal transmitted by the National Institute of Standards and Technology (NIST). Most atomic clocks in North America use WWVB's transmissions to set the correct time automatically. ![]() Atomic clock is an extremely Accurate Timepiece.Shape: Rectangular LFF atomic clock with indoor temperature and humidity & adjustable backlight How do Atomic Clocks Work? Room Type: Living Room, Bedroom, Home Office, Dining Room The Docking Station provides the status of each AR50-05 unit including battery status, frequency lock and deviation from the desired frequency as well as recording and storing the data obtained from the field calibration.Special Feature: Loud Alarm, Multiple Time Zone, Adjustable Brightness, Atomic When the AR50-05 calibration case is connected to the Docking Station the case is loaded with the protected time and 1PPS and the battery is charged. The Docking Station is fully redundant and includes a highly accurate and stable reference clock that is protected from GNSS jamming and spoofing using AccuBeat’s proprietary technology. At each affected site or platform, the case is easily connected to the system with the cables supplied and both TOD and accurate 1PPS information can be “injected” into the receiving clock thereby ensuring full frequency, TOD and 1PPS synchronization across multiple platforms without the need for a GNSS signal.Ĭustomers who have multiple AR50-05 Calibration cases can store them in AccuBeat’s Docking Station that will simultaneously synchronize up to 12 units ensuring uniform time and frequency in each unit. When a need for external synchronization arises - such as in the case of jamming or spoofing - the AR50-05 calibration case can be easily transported to the required site while the internal atomic clock keeps the accurate TOD and 1PPS, taking its power from either an external DC input or from its own internal battery. This Ruggedized portable case contains an accurate atomic clock, an internal backup battery, a tablet and easy to use Graphical User Interface for performing the calibration, as well as all the required cables to synchronize various types of Atomic clocks. With this in mind, AccuBeat has designed and delivered to its customers a portable calibration case, the AR50-05, providing the user with a comprehensive solution for time dissemination in any GNSS denied environment. However, it has been well recognized that the any GNSS (GPS, GLONASS, Galileo…) signal can easily be blocked, jammed or spoofed intentionally or unintentionally, thereby preventing correct initial setup of the equipment and consequently posing a serious threat on the overall performance of the system or mission. Most platforms and systems already deploy advanced Rubidium atomic clocks for timing and synchronization - many of which are manufactured and supplied by AccuBeat - and in almost all cases a GNSS signal is needed in order to input the initial time into the platform. The wide spectrum of applications encompasses the fields of Navigation, Communications, Identification, Remote Sensing, Intelligence, and Weapons. Numerous critical applications and equipment rely on GNSS systems for providing timing and synchronization.
