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

Thomas Debrunner 43bc6db99e PPS capture: Add a param to enable / disable PPS capture module. This is important, since it takes over an FMU pin which can no longer be used for actuator output. 2021-12-17 07:56:08 +01:00
