WebNGA extrapolates the current and future offset of Earth's inertial orientation to the WGS 84 reference frame's orientation by fitting 435 days of polar X and Y axes locations and 32 days of UT1-UTC differences from USNO and a zonal Earth tide model. ... This coordinate frame translation is part of NGA's maintenance of the WGS 84 reference frame. WebThe most popular model is WGS84, used by most modern maps and also by the Global Positioning System (GPS). If you are given a longitude and latitude without a datum specified, they are probably WGS84 coordinates. You can pass the latitude and longitude to a datum like WGS84 by calling its latlon () method.
