gcrf_to_lat_lon

ssapy.utils.gcrf_to_lat_lon(r, t)[source][source]

Converts a position vector in the GCRF (Geocentric Celestial Reference Frame) to latitude, longitude, and height coordinates on Earth.

Parameters:

r (array-like): The position vector in GCRF coordinates (x, y, z) in meters. t (datetime or float): The time associated with the position vector.

This can be a datetime object or a timestamp in seconds.

Returns:

tuple: A tuple containing:

  • lon (float): Longitude in degrees (East-positive).

  • lat (float): Latitude in degrees (North-positive).

  • height (float): Height above the Earth’s surface in meters.

Note:

This function relies on the groundTrack function from the .compute module to perform the conversion.
