Re: Geotagging Photos


GPS or as it is known today as GNSS is a constellation of sats that provide signals that GPS/GNSS receivers can decode to calculate their exact location. that signal is constant. there is no GPS provider other than the US Govt (there are other systems of different freqs and usable locations). minimum 4 GPS sats to get a precision location. the chip in your device does the all the math (kalman filtering). the more strong signals your receiver can capture the more precise your position can become. there are variables that can throw off that precision.
US provider: Navstar US Govt USAF (Z9 supported)
Russia: Glonass (Z9 supported and various gps supported)
QZSS: Japan (Z9 supported)**
China: Beidou (solmeta supported)
EU: Galileo
the availability/usability of these systems will vary by location and the receivers.
the availability of said systems constellations varies considerably.
