Detailed Description

CUDA counterpart of isce3::core::Orbit.

This class exports a host-side interface for managing and interacting with orbit data residing in device memory. It is not intended for use in device code - use OrbitView instead.

Constructor & Destructor Documentation

◆ Orbit() [1/2]

isce3::cuda::core::Orbit::Orbit	(	const std::vector< isce3::core::StateVector > &	statevecs,
		isce3::core::OrbitInterpMethod	interp_method = isce3::core::OrbitInterpMethod::Hermite )

Construct from list of state vectors.

Reference epoch defaults to time of first state vector

Parameters

[in]	statevecs	State vectors
[in]	interp_method	Interpolation method

◆ Orbit() [2/2]

isce3::cuda::core::Orbit::Orbit	(	const std::vector< isce3::core::StateVector > &	statevecs,
		const isce3::core::DateTime &	reference_epoch,
		isce3::core::OrbitInterpMethod	interp_method = isce3::core::OrbitInterpMethod::Hermite )

Construct from list of state vectors and reference epoch.

Parameters

[in]	statevecs	State vectors
[in]	reference_epoch	Reference epoch
[in]	interp_method	Interpolation method

Member Function Documentation

◆ interpolate()

ErrorCode isce3::cuda::core::Orbit::interpolate	(	isce3::core::Vec3 *	position,
		isce3::core::Vec3 *	velocity,
		double	t,
		isce3::core::OrbitInterpBorderMode	border_mode = isce3::core::OrbitInterpBorderMode::Error ) const

Interpolate platform position and/or velocity.

If either position or velocity is a null pointer, that output will not be computed. This may improve runtime by avoiding unnecessary operations.

Parameters

[out]	position	Interpolated position
[out]	velocity	Interpolated velocity
[in]	t	Interpolation time
[in]	border_mode	Mode for handling interpolation outside orbit domain

Returns: Error code indicating exit status
