Note: Timestamps and Sensor Synchronization¶
You are probably here because callbacks are not lining up, fusion quality is inconsistent, or a multi-sensor pipeline behaves differently on replay than it did live.
Likely First Answer¶
Start with Timestamp Discipline and Message Synchronization.
If the Real Problem Is...¶
- ROS time model confusion: ROS 2 Time, Duration, and Sim Time
- sync policy tuning: message_filters and Time-Synchronized Sensors
- multi-machine clock assumptions: ROS 2 Multi-Machine Networking and Discovery
- downstream fusion instability: Multi-Sensor Fusion Patterns
