Detailed Description

Store and interpolate attitude measurements.

Constructor & Destructor Documentation

Constructor.

Parameters

[in]	time	Time tags, seconds since some epoch. Must be strictly increasing.
[in]	quaternions	Unit quaternions representing antenna to XYZ (ECEF) rotation.
[in]	epoch	Reference epoch (UTC) for time tags.

Attitude isce3::core::Attitude::crop	(	const DateTime &	start,
		const DateTime &	end,
		int	npad = 0 ) const

Create a new Attitude containing data in the requested interval.

Parameters

[in]	start	Beginning of time interval
[in]	end	End of time interval
[in]	npad	Minimal number of quaternions to include past each of the given time bounds (useful to guarantee adequate support for interpolation).

void isce3::core::Attitude::referenceEpoch ( const DateTime & epoch )

Set reference epoch (UTC)

Updates contents of time() so that referenceEpoch() + TimeDelta(time()[i]) remains the invariant.
