Precise time mark using camera trigger and RAW GPS module

Any Ublox with RAW data capability can be used for precise time measurements with sub-microsecond resolution using the external interrupt on the GPS module. This will be really good to timestamp each picture taken for mapping purposes. A connection between the trigger of the camera and the GPS has to be made ( TTL levels ).
This function can be well integrated together with the new RAW data log capability function.

For reference: look on page 12 of the UBlox datasheet, (1.15.3)
