[QUOTE="mha1, post: 80717, member: 12174"] Please try and get a basic idea of how the GPS system works to understand your observations. You might want to start here: [URL="https://en.wikipedia.org/wiki/Global_Positioning_System"]Global Positioning System - Wikipedia[/URL] [URL="https://en.wikipedia.org/wiki/Dilution_of_precision_(navigation)"]Dilution of precision (navigation) - Wikipedia[/URL] This is a good basic read to understand why it sometimes takes more time to aquire a first fix: [URL="https://www.e-education.psu.edu/geog862/node/1739"]The Almanac, Time to First Fix and Satellite Health | GEOG 862: GPS and GNSS for Geospatial Professionals[/URL] To the question of recharchable battery: all modern GPS receivers have some means on storing dowloaded GPS system data in non-volatile oder battery buffered memory to be able to do acquisition warm starts even if the main system (your drone) is taken off power. But it is in the nature of the GPS system that it might take up to 12 minutes worst case to obtain a first fix. So all your observations about varying times to first fix are perfectly within the to be expected range. [/QUOTE]
