Orbit Enumerations¶
Enumerations for specifying orbit representation types and reference frames.
OrbitRepresentation¶
Specifies the type of orbital elements being used.
OrbitFrame¶
Reference frame for orbital trajectory representation.
Specifies the coordinate reference frame for position and velocity states.
Initialize instance.
class-attribute ¶
ECEF: Any = OrbitFrame(Earth-Centered Earth-Fixed)
Reference frame for orbital trajectory representation.
Specifies the coordinate reference frame for position and velocity states.
class-attribute ¶
ECI: Any = OrbitFrame(Earth-Centered Inertial)
Reference frame for orbital trajectory representation.
Specifies the coordinate reference frame for position and velocity states.
class-attribute ¶
EME2000: Any = OrbitFrame(Earth Mean Equator and Equinox of J2000.0)
Reference frame for orbital trajectory representation.
Specifies the coordinate reference frame for position and velocity states.
class-attribute ¶
GCRF: Any = OrbitFrame(Geocentric Celestial Reference Frame)
Reference frame for orbital trajectory representation.
Specifies the coordinate reference frame for position and velocity states.
InterpolationMethod¶
Python bindings for trajectory traits and orbital trajectory. Interpolation method for trajectory state estimation.
Specifies the algorithm used to estimate states at epochs between discrete trajectory points.
Initialize instance.
class-attribute ¶
HERMITE_CUBIC: Any = InterpolationMethod.HERMITE_CUBIC
Python bindings for trajectory traits and orbital trajectory. Interpolation method for trajectory state estimation.
Specifies the algorithm used to estimate states at epochs between discrete trajectory points.
class-attribute ¶
HERMITE_QUINTIC: Any = InterpolationMethod.HERMITE_QUINTIC
Python bindings for trajectory traits and orbital trajectory. Interpolation method for trajectory state estimation.
Specifies the algorithm used to estimate states at epochs between discrete trajectory points.
class-attribute ¶
LINEAR: Any = InterpolationMethod.LINEAR
Python bindings for trajectory traits and orbital trajectory. Interpolation method for trajectory state estimation.
Specifies the algorithm used to estimate states at epochs between discrete trajectory points.
property ¶
degree: int
Get the polynomial degree for Lagrange interpolation.
Returns:
| Type | Description |
|---|---|
int | int | None: The degree if this is a Lagrange method, None otherwise |
property ¶
min_points_required: int
Get the minimum number of data points required for this interpolation method.
Returns:
| Name | Type | Description |
|---|---|---|
int | int | Minimum number of points required |
staticmethod ¶
lagrange(degree: int) -> InterpolationMethod
Create a Lagrange polynomial interpolation method.
Lagrange interpolation requires degree + 1 data points. Higher degrees provide more accuracy but can oscillate (Runge's phenomenon) for poorly distributed points.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
degree | int | Polynomial degree for Lagrange interpolation (must be >= 1) | required |
Returns:
| Name | Type | Description |
|---|---|---|
InterpolationMethod | InterpolationMethod | Lagrange interpolation method with specified degree |
Raises:
| Type | Description |
|---|---|
ValueError | If degree is less than 1 |
