pyinterp.orbit.Orbit

class pyinterp.orbit.Orbit(height, latitude, longitude, pass_time, time, x_al, wgs)

Bases: object

Represent properties of the orbit.

Store and manage orbital parameters including position, timing, and geodetic information.

Parameters:

• height (float) – Height of the satellite (in meters).

• latitude (NDArray1DFloat64) – Latitudes (in degrees).

• longitude (NDArray1DFloat64) – Longitudes (in degrees).

• pass_time (NDArray1DTimeDelta64) – Start date of half-orbits.

• time (NDArray1DTimeDelta64) – Time elapsed since the beginning of the orbit.

• x_al (NDArray1DFloat64) – Along track distance (in meters).

• wgs (Spheroid | None) – World Geodetic System used.
