grss.fit.fit_utils.parallax_to_lat_lon_alt

grss.fit.fit_utils.parallax_to_lat_lon_alt(lon, rho_cos_lat, rho_sin_lat)

Convert parallax constants to geocentric longitude, latitude, and distance.

Parameters:

• lon (float) – degrees, longitude of observer

• rho_cos_lat (float) – rho cos phi’, where rho is the distance from the geocenter to the observer and phi’ is the geocentric latitude of the observer

• rho_sin_lat (float) – rho sin phi’, where rho is the distance from the geocenter to the observer and phi’ is the geocentric latitude of the observer

Returns:

• lon (float) – radians, longitude of observer

• lat (float) – radians, geocentric latitude of observer

• rho (float) – distance from the geocenter to the observer, m
