Where were you going that you didn't have GPS coverage for 30 miles? GPS coverage works even without Network/WiFi coverage. I find it very, very unlikely inert

GPS coverage works even without Network/WiFi coverage. I find it very, very unlikely inertial tracking using iPhone inertial sensors would be accurate up to 30 miles.
Could you provide a source please on the fact that iPhones use inertial navigation for predicting location (either public or private apis)

- mjlee 7y agoIt doesn't really matter how rural the area is - GPS works pretty well outside of the polar circles. AGPS does use data connection to accelerate first fix time, but will be accurate after that without data.
- quenstionsasked 7y agoThis link just says that the M7 is still active after main phone has shut down. Nothing about inertial navigation.
