The 5071A is the most accurate commercial atomic clock available. It has an accuracy of less than 5E−13 under all environmental conditions and no deterministic frequency drift. The capabilities and reliability of the 5071A make it the single largest contributor of cesium clocks—more than half of all contributing clocks—to Coordinated Universal Time (UTC). The 5071A is the world’s leading timing solution for strategic defense assets and critical civilian and government infrastructure, with the ability to deliver submicrosecond holdover for months at a time during Global Navigation Satellite System (GNSS) denial.
Key Features:
