Parameters:

input_paths (string or path-like or list of paths) – Path to measurement sp3 file(s).

interpolate_sp3(navdata, window=6, verbose=False)[source]

Interpolate ECEF position data from sp3 file, inplace to given navdata instance.

Parameters:

  • navdata (gnss_lib_py.navdata.navdata.NavData) – Instance of the NavData class that must include rows for gps_millis and gnss_sv_id.

  • window (int) – Number of points to use in interpolation window.
