Just a quick report, I have had some success with accurate geotags using the KAP log time stamps - the time stamping is accurate enough to be useful in combination with post processed RTK GPS data, I have achieved sub metre precision, with the majority of tags within 30cm of the calculated image positions using Pix4d. This is the limit of accuracy of the GPS system at the moment, bu with more accurate position data clock syncing between GPS becomes even more of an issue.
Unfortunately the
S100 GPS clock sync is not accurate enough - I have had to use trial and error to discover an offset which works for a given project, not impossible but time consuming.
I guess the
S100 internal clock received GPStime, applies the UTC offset and rounds to the nearst second at some point? A shame as it clearly could get an accurate sync in terms of hardware...
