Verification of IEEE1588 time synchronization in NASA agate data bus standard

Time synchronization quality of measurement devices plays critical role under necessity of precise data sampling, e.g. for usage of the Kirchhoff Current Law. This article proposes new arrangement of aircraft inertial sensors, that are spread over an airplane construction and needs to be time synchronized. Generally a single signal wire is used for time synchronization for local networks or they rely on their internal timers. The IEEE standardized a time synchronization algorithm designed for packet network such Ethernet. In this paper we propose usage of IEEE1588 over the Agate data bus based on the CAN bus in order to synchronize group of inertial sensors. In addition precision of the time synchronization is measured and compared.
