- www.nature.com Mapping the ionosphere with millions of phones | Nature
The ionosphere is a layer of weakly ionized plasma bathed in Earth’s geomagnetic field extending about 50–1,500 kilometres above Earth1. The ionospheric total electron content varies in response to Earth’s space environment, interfering with Global Satellite Navigation System (GNSS) signals, resulti...

Contribute network location data to get location everywhere without sattelites!
tux.social Rhababerbarbar (@Rhababerbarbar@tux.social)Wie geht einfache schnelle Standortbestimmung überall,, auch in Gebäuden und ohne Satteliten? Hier hilft #NLP (network location position), also Standortbestimmung ohne #GPS oder #AGPS Mithilfe von Datenbanken kann dein Handy dir so sagen, wo du bist, aufgrund von umliegenden Mobilfunktürmen, WLan...
Opensource geodata of celltowers, wifis and bluetooth beacons is crucial.
It allows apps like UnifiedNLP to give the OS the location data it needs, without relying on GPS Sattelites.
GPS can be tampered with, and A-GPS is not privacy friendly at all.
UnifiedNLP is only found included in microG, which is pretty insecure.
But GrapheneOS devs are working on a regular user app that serves network location data, using Apple, Apple (proxied) or a local BeaconDB database!
BeaconDB is a new service to replace MozillaLocationServices which has shut down unfortunately.
Apps like TowerCollector dont yet support it, but NeoStumbler does, and also has more advanced features.
Collect network info in your region, and in the future you (and everyone else using it) dont need GPS anymore!
