Side note: > The current Android platform supports GPS, SBAS, GLONASS, QZSS, BEIDOU, GALILEO, and IRNSS[0]. But it depends (and varies wildly) on the hardware of said Android. I buy 3 to 5 cheap (sub 100 euro/US$) Androids per year and it always surprises me which device supports which GNSS is supported and how accurate or not they are. PS I use them to Wigle (https://wigle.net https://wigle.net) mainly, and the WiFi reception is exactly as diverse as the GNSS.
