Is GPS positioning technology photogrammetry or satellite measurement?
GPS positioning technology is satellite measurement. You can calculate your latitude and longitude by receiving the elevation signal of each satellite signal and the height data of the satellite body.
Note that this latitude and longitude is a latitude and longitude parameter relative to the absolute elevation of a standard. If the elevation of your place is not equal to the standard elevation, you need to use the elevation value of this place for coordinate correction.
