A primitive time synchronization method is proposed based on the FC-AE-1553 bus technology, aiming at the comprehensive development of onboard measurement systems and the background demand for real-time data sensitivity. This method enables each node in the FC-AE-1553 bus to have the same-time reference. On the basis of time synchronization, a scheduling timing based on time synchronization wasdesigned to collect real-time data from various NT nodes, meeting the requirements of real-time data for onboard measurement systems. The experimental results show that the FC-AE-1553 bus designed has nanosecond time synchronization, dual redundancy, and other functions, which meet the application requirements-of onboard measurement systems and improve the comprehensive level of onboard measurement systems.
