no GPS is relative. Most phones have AGPS - while this works fine in a city, have fun finding, where you took that picture in a remote forest. Actual, independent GPS devices still cost a lot of money (and need power).
- ghaff 7y agoI have a rugged point and shoot that has just GPS. It takes a bit to find a lock and does run down it’s smoothly with no cellular. But there’s definitely GPS in cheap devices. For that matter you can get $100 standalone GPS receivers.
- NickNameNick 7y agoAGPS devices are still GPS devices. They just fast-load the ephemera/almanac data from the cell network instead of waiting to get it from the GPS signal. I know there are options for offloading the GPS signal analysis to other devices, but I wasn't aware of any main-stream cellphones that can't use GPS without the network.
- ghaff 7y agoI’ve definitely used my iPhones at any rate as GOS receivers where no cell signal was available. It just takes longer to get a lock.
