IEEE 802.1Qbv TSN Schedulers and Microsecond Clock Synchronization (IEEE 1588 PTP)

Hardware-timestamped IEEE 1588v2 PTP clocks and 802.1Qbv time-aware shapers guaranteeing bounded latency for critical motion and safety packets.

IEEE 1588v2 PTP Grandmaster Distribution

UGVSync synchronizes all onboard compute nodes, sensors, and remote motor inverters to within ±250 nanoseconds using hardware-assisted IEEE 1588v2 PTP over Gigabit automotive Ethernet, preventing phase drift during synchronized tandem operations.

Time-Aware Shaper (TAS) Slot Allocation

By reserving cyclically repeating microsecond time slots via IEEE 802.1Qbv, safety-critical motion commands traverse the network with zero queueing jitter, strictly isolated from high-bandwidth LiDAR point cloud and video streams.

Hardware timestamping with sub-250 ns clock synchronization
IEEE 802.1Qbv cyclic time-aware traffic scheduling
Redundant grandmaster clock failover compliant with IEEE 802.1AS
Zero packet collisions for ISO 13849 safety data frames
