This standard is applicable to systems operating under the Space Plug-and-Play Architecture (SPA).

The SPA System Timing Standard establishes a common method for providing common timing within a system of networked SPA components.

Discussions on availability, latency, jitter, and drift provide general guidelines on system timing requirements which are intended to meet the needs of most systems. Systems requiring greater timing accuracy than described herein may be implemented within the Space Plug-and-Play Architecture with enhanced or modified timing provisions as necessary.
