Michael Schaeuble	5ad8b84dec	Fix PPS based UTC timestamp in camera trigger and capture messages The existing implementation has about 100ms difference to a reference clock. With the changes this error less than 25us. - Use sensor_gps messages with hrt timestamps as RTC reference and not the system realtime clock. The PPS interrupt can then be aligned with the GPS clock system. - Keep fallback based on system RTC when no PPS pulse was captured	2021-12-17 07:56:08 +01:00

Fix PPS based UTC timestamp in camera trigger and capture messages

The existing implementation has about 100ms difference to a reference clock. With the changes this error less than 25us.
- Use sensor_gps messages with hrt timestamps as RTC reference and not the system realtime clock. The PPS interrupt can then be aligned with the GPS clock system.
- Keep fallback based on system RTC when no PPS pulse was captured
