When the sequoia reports that it has a gps lock but only has around 6-8 satellites it often starts gps capture mode successfully but then drops out without notice.
This is also causing problems for the radiometric capture. if you start a radiometric capture when the previous mode was gps (even if not capturing), if the gps lock status changes it seems to cancel the radiometric capture.
I may work around the radiometric capture issue by temporarily changing the capture mode to single capture before starting a radiometric capture to avoid gps lock changes. This seems to work.
Are there conditions that would cause a gps capture to cancel by itself?
