I have used OSMand in the past on an Android phone and use it now on an iPhone 6s+. I've been testing it against Apple maps and Google Maps recently and I've noticed that although all 3 apps use the same GPS hardware, the GPS in terms of error circle size and center accuracy is much worse when I'm using OSMand than when I'm using one of the other two apps. Could this be because a determination is being made in the other two apps that I'm moving slowly enough that I must be walking and thus an update to the correct position with a small error circle, doesn't need to jump to a big error circle quickly nor have the whole circle jump because I can't walk that fast. What else besides something like Kalman filtering that I'm thinking of can the other programs be doing? Is there a plan to improve performance on OSMand? It's bad enough that I'm wanting to by a separate GPS logger and move tracks over later on a computer and not bother with phone.
As an aside, I can't wait till 1 meter accurate GPS receivers (e.g. http://bad-elf.com/blogs/bad-elf/15489204-new-product-bad-elf-gnss-surveyor-with-1-meter-accuracy) drop in price a lot more. I look forward to seeing devices use the new civilian GPS signals will help use the additional civilian signals being deployed. Then I'll be able to take a really good trail survey and edit the OSM accurately. -- You received this message because you are subscribed to the Google Groups "Osmand" group.
