RE:RE:RE:RE:What I like about this companyYes it's a function of view distance, so at 15km the error is 150 meters. Look at your own chart, those are all from a drone/camera holding position as the drone moves or looks at farther distances the error will compound. The two two tests were done in perfect conditions, what happens when the terrain looks different due to clouds, weather or time of day? No navigation! What happens when the terrain changes from war? No navigation.
