Constructor & Destructor Documentation

ENUUtil()

gnsstk::ENUUtil::ENUUtil	(	const double	refGeodeticLatRad,
		const double	refLonRad
	)

Given a location as a (geodetic) latitude and longitude the constructor creates the appropriate rotation matrix from XYZ to ENU and retains it for later use.

Parameters

refGeodeticLatRad	geodetic latitude of point of interest (radians)
refLonRad	longitude of point of interest (radians).

inVec

)

const

Convert from a vector in ECEF XYZ to ECEF ENU using the current rotation matrix.

Parameters

[in]

inVec

vector of interest in ECEF XYZ.

Returns

Same type as input but with the vector in ECEF ENU

Definition at line 90 of file ENUUtil.cpp.

inV

)

const

Convert from a vector in ECEF XYZ to ECEF ENU using the current rotation matrix.

Parameters

[in]

inV

convertToENU() [3/3]

gnsstk::Xvt gnsstk::ENUUtil::convertToENU

(

const gnsstk::Xvt &

in

)

const
