This will not have the same feature set but the UI will let you know that this is operating with reduced data. Route planning is still very good offline. I had to use this feature because for some time part of my route home had no cell signal.
- rch 5y agoI use this hiking sometimes. Not as good as GPS obviously, but better than AllTrails.
- Eelongate 5y ago> Not as good as GPS obviously It is GPS.
- gravypod 5y agoYou might be misunderstanding. They parent may be saying that they download the maps and just search for a road and use it like a paper map. Also, "GPS" in the United States colloquially refers what people in the UK would call "sat-nav" not to the satellites + protocol (what it actually means on paper).
- Eelongate 5y ago> You might be misunderstanding. They parent may be saying that they download the maps and just search for a road and use it like a paper map. Maybe? When hiking it makes some sense to forego GPS to save battery power. I didn't consider that possibility when I commented earlier, but in my defense the context of the comment is using maps without an internet connection. > Also, "GPS" in the United States colloquially refers what people in the UK would call "sat-nav" Sure, but sat-nav doesn't require internet service...
- tekno45 5y agodoesn't that still allow GPS communication?
- Eelongate 5y agoIt certainly does. Pure inertial guidance with smartphone sensors is garbage. I must say I'm a bit startled by how many people evidently think that GPS is an internet service...
- nradov 5y agoCell phones use A-GPS which relies on cellular data service. It allows for faster position fixes using base station signals. Of course a cell phone with a view of the sky can still get a position fix entirely from satellites, it just takes a little longer.
- Eelongate 5y agoI've used GPS navigation extensively on my phone with no internet service; I drove clear across Canada with my simcard pulled, it works fine. If I had to guess, these conflations of cell service with GPS are a product of misleading UX created by Google. OSMAnd makes the nature of GPS clear, displaying a count of satellites it's managed to hear. Enough satellites to get a location good enough for car navigation almost always takes less than a minute.
- astrange 5y agoThere are some other aspects of locations that use downloaded data, like building heights, wifi base station locations, etc.
- gravypod 5y agoYes, it does but knowing where you are isn't the problem for these systems it seems. Also, you can get very far with inertial tracking: https://en.wikipedia.org/wiki/Inertial_navigation_system https://en.wikipedia.org/wiki/Inertial_navigation_system Couple that with point clouds of the sea floor, manual input from humans, etc, you can do quite well.
