Aaronia has announced the PULSAR GNSS-Disciplined Multi Clock Standard, a high-precision coherent timing and frequency reference solution designed for demanding RF, radar, and spectrum monitoring applications. The system provides coherent 10 MHz, 100 MHz, and 1 GHz outputs with ultra-low phase noise, jitter, and drift. It is scheduled to be available in Q2 2026.
The PULSAR clock standard uses a GNSS-disciplined reference architecture with either a TCXO or OCXO oscillator option to deliver highly stable and accurate timing synchronization. The system supports timing accuracies of up to 5 ppb using a TCXO reference and 200 ppt using an OCXO reference. Designed for precision RF measurement and synchronization applications, the platform is optimized for passive radar deployments, multi-station TDOA systems, and ultra-accurate frequency monitoring networks.
The system delivers phase noise performance of -165 dBc/Hz at 10 kHz offset for 10 MHz, -180 dBc/Hz at 10 kHz offset for 100 MHz, and -155 dBc/Hz at 10 kHz offset for 1 GHz signals.
The PULSAR coherent time base has been designed to integrate with the company’s SPECTRAN V6 spectrum analysis platform. Integrating the GNSS-disciplined coherent reference with SPECTRAN V6 systems enables highly synchronized distributed RF measurement setups worldwide, supporting advanced applications such as passive radar, geolocation, and precision frequency monitoring.
