Constructor & Destructor Documentation

NEDUtil()

gnsstk::NEDUtil::NEDUtil	(	const double	refGdLatRad,
		const double	refLonRad
	)

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

Parameters

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

convertToNED() [1/3]

gnsstk::Triple gnsstk::NEDUtil::convertToNED

(

const gnsstk::Triple &

inVec

)

const

Convert from a vector in ECEF XYZ to ECEF NED 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 NED

Definition at line 93 of file NEDUtil.cpp.

convertToNED() [2/3]

gnsstk::Vector< double > gnsstk::NEDUtil::convertToNED

(

const gnsstk::Vector< double > &

inV

)

const

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

Parameters

[in]

inV

vector of interest in ECEF XYZ.

Returns

Same type as input but with the vector in ECEF NED

Definition at line 80 of file NEDUtil.cpp.

convertToNED() [3/3]

gnsstk::Xvt gnsstk::NEDUtil::convertToNED

(

const gnsstk::Xvt &

in

)

const

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

Parameters

[in]

in

vector of interest in ECEF XYZ.

Returns

Same type as input but with the vector in ECEF NED

Definition at line 105 of file NEDUtil.cpp.

updatePosition()

void gnsstk::NEDUtil::updatePosition	(	const double	refLatRad,
		const double	refLonRad
	)

Update the rotation matrix to the new location without creating a new object

Parameters
