Synchronization, continued...
- Station #1 and #2 indicate 1 received station. Station #3 indicate 2.
- Who becomes the semaphore?
1. If all stations lack UTC, #3 will become the semaphore and increase its report rate to 2 seconds. #1 and #2 will synchronize on #3.
2. If #2 indicates UTC Direct, #3 will indicate UTC Indirect and synchronize on #2, #1 will then also indicate UTC Indirect and synchronize on #3. Station #3 and #2 will increase their update rates to 2 seconds (they are both semaphore qualified).
3. Any station indicating UTC Direct, will use the UTC source only. The state of other stations is ignored.
