time lag in tracklog GPX?

[ralfhesse]

Hi,



is it possible that Oruxmaps does not write the correct (GPS-based) time stamp into the GPX track log files? I have compared the logs created by Oruxmaps (using an external i-blue 747 bluetooth GPS) with a GP-102 and a GT-11 GPS logger (which have identical time stamps) and have found that Oruxmaps has a time lag of 15 seconds (i.e. roughly 400 m 2D distance when driving in a car). System time on my android device is only one second off, so this can not be the problem either. I also noted that when walking around with the device, the track displayed seemed to keep "crawling" for a while after I stopped. Does anybody have an explanation or a solution?
