Another example is distributed phase array element synchronization for Very High Frequency (VHF) and Ultra High Frequency (UHF) systems. This solution is ideal for many wireless communications systems such as network of fire control radars to exchange targeting information in real-time, or real-time video from multi-static radars. Systems requiring free-running synchronization over hours or days, such as Time Division Multiple Access (TMDA) networks, are concerned about long-term stability to maintain a highly accurate synchronization level while being on a low power and radio silent sleep mode.Ī second-generation atomic clock is the best solution to provide such backbone networks with required precise synchronization and long-term stability, thanks to its holdover function in a GNSS-denied environment. Next-Gen atomic clocks: An optimized frequency source In the battlefield, for example, it is critical to get precise date and time-stamping to ensure a reliable end-to-end data collection process in Intelligence, Surveillance and Reconnaissance (ISR) applications. There are many applications where relying on stable and reliable GNSS reception is not an option. Having a local atomic clock to provide an accurate and stable frequency can alleviate this problem. By synchronizing to the atomic clocks in the GNSS satellites, the GNSS receiver will also get a global time reference, such as Universal Coordinated Time (UTC), to be used as a common reference across a wide geographic area, which is necessary in multi-static radars, distributed arrays, or in wireless Wide Area Network (WAN) applications.īecause GNSS satellites broadcast from Mid Earth Orbit (MEO), approximately 20K km above the earth, they make signal reception very weak and can therefore be easily interfered with or jammed. Precise and accurate timing: A battlefield necessityĪny Global Navigation Satellite System (GNSS) can be used to discipline a local oscillator (LO) to provide higher frequency accuracy than a standalone device. These next generation atomic clocks can now operate over wide temperature ranges in harsh environments with improved reliability and phase noise. Today, the second generation of miniature atomic clocks is now available and can reach a new level of accuracy and stability (~100x over high-end OCXOs) while still maintaining the low SWAP attributes. The first generation of Chip Scale Atomic Clocks (CSAC) became available on the market, offering ~10x or more improvement in accuracy and stability over a high-end OCXO in a low SWAP package.

Windows (8 / 8.1 / 10) and Mac OS X 10.Radars and wireless communication applications rely on highly precise and stable frequency sources to use as local oscillators (LO).Ī standard oven-controlled quartz oscillator (OCXO) provides the required level of accuracy and stability by adding a GNSS receiver to phase and frequency, and locks the LO to the precise atomic clock references in the satellites.īut how do you achieve high accuracy and stability when GNSS signal is not available or practical?Ī few years ago, the simple idea of implementing an atomic clock as an LO source instead of the classic OXCO was a design improvement to be considered very carefully in terms of budget, and the impact of Size, Weight, and Power (SWaP) on the final design.

4 WC BNC outputs 768 kHz (Square wave signal).

In addition, the unit provides clock outputs for the AES / EBU and SPDIF formats.Īll functions and controls are easily managed from the front panel or with the unit connected to a Mac or Windows computer via USB, through an intuitive software control panel. It can also be used as a master clock with BNC word clock outputs, supporting sampling rates of up to 768 kHz. The 10MX is equipped with BNC atomic clock outputs, generating a 10 MHz signal that allows you to control up to 10 devices simultaneously. The Antelope Audio 10MX is a Rubidium Digital Master Clock that fuses the atomic precision of the 10M and the innovative Trinity´s jitter-management algorithm.
