SmartGNSS

Geolocation

Via GNSS RAW

Using Rokubun's Jason service (https://jason.rokubun.cat), we send Android's GNSS raw data and compare the resulting coordinates with the user's provided coordinates.

Via IP

Using ipinfo.io within its free tier. Sending an IP address.

Via WiFi

WiGLE Documentation

Using wigle.net within its free tier. Sending the SSID of a WiFi router.

There is the possibility of sending coordinates to reduce the search area.

NOTE: Response is hardcoded since they have a limitation of 5 queries per day.
