GPS location Accuracy

[SteveJG]

This is what MIT says:

Is the App Inventor LocationSensor 'out of date'; It seems to use only a few of the available satellite 'constellations'

We use whatever the system returns as being the most best provider for the given parameters you set. You can see the full list of providers and the chosen provide by using the corresponding properties: AvailableProviders and ProviderName. For example, I get a fix almost immediately in my home office on a Google Pixel 6 with Android 14. The provider it selects is "fused".

Yes, using the LocationSensor simultaneously with having Google Maps active does appear to improve 'accuracy'. I think that is because these apps trigger the device hardware gps receiver to make use of all the 'constellations' whereas App Inventor may be only using the original one or two constellations. MIT doesn't seem to agree as shown in the above link.

Satellites used by App Inventor. It is not using all available constellations on my Android 13.

Satellites used by other mapping/ positioning software at more or less the same time showing they are using almost double the 'channels'/satellites in their fix.

Here are some other discussions about the often POOR quality of positioning of App Inventor coordinates versus Google Maps and other mapping software. Several make mention of using App Inventor in conjunction with 'other' mapping software to improve accuracy. I expect this may happen because the 'other' software uses all the channels available to one's hardware gps receiver on the device and App Inventor doesn't.

Hello, I'm struggling a bit with location sensor... Trying to get the speed but Is almost not working. If I open an external GPS logger than the accuracy increase a lot. It seems that sensore location do not fix enough satellites...

Google Maps and the Location Sensor (running simultaneously to achieve better Accuracy)

Hello all, I cannot find much on the internet about this but I noticed and interesting phenomenon. In my Inventor App if I ONLY use code blocks to move an updating marker on a map to the current Latitude and Longitude on the map and notice the accuracy isn't that great regardless of update intervals of time or distance. I would say in some cases off by 30 meters especially while moving in car. While the aforementioned Inventor App is running AND I have the Google Maps app in the process to n…

Location accuracy sometimes poor (half a mile out) on new phone

I have written an app which uses GPS data. On my old phone (Android 8.1, bought in 2018) it works perfectly. But I have recently bought a new phone (Android 13) and sometimes (not always) the GPS location data is wrong by up to about half a mile. Google maps always gets the location right, so why can't App Inventor and my new phone be more reliable? Any help much appreciated!

GPS with Android 12

it seems that the refresh of the GPS position does not work well with Android 12
