GNSS enhancements bundle #701
Description
Internal provider (no external device)
Android
-
fused is now by default
-
system reports ellipsoid heights
-
we transform to EGM96 by default
- geoid height + ellipsoid height values are available
-
transforming to chosen geoid is available and geoid height + ellipsoid height values are also available
iOS
-
system reports msl heights
- by default we do not do any transformations, simply accept whatever is coming from the system
- geoid height + ellipsoid height values are not available
-
transforming to chosen geoid - @Withalion ?
External provider - Mock
- If there is no transformation, we accept data as they come
- geoid height + ellipsoid height values are not available
- Transforming to chosen geoid is available, but users must set the mock app to send ellipsoid heights, otherwise undulation would be applied twice
iOS
- iOS only sends a minimal subset of available GPS data - x, y, z (no accuracy,...)
External provider - Bluetooth
- Available only on Android
- If there is no transformation, we accept data as they come
- geoid height + ellipsoid height values are available, but we do not know the selected geoid model
- transforming to chosen geoid is available and geoid height + ellipsoid height values are also available + we know the geoid model and show it in the app
External provider - Network
(same as bluetooth)

Name of position provider has been changed if mock location is detected to "External (Mock)"
Variables
@position_geoid_separation@position_elevation_ellipsoid@position_elevation(will have the same value as@position_altitude) Return altitude variable mobile#4333@position_provider_namewill be "External (Mock)" if mock location is detected Fix position provider name variable mobile#4348Android
seems right
iOS
External - Mock
geoid heightdo you mean separation?Android
External - Bluetooth
seems correct
External - Network
correct, but should be available on all platforms
