X_ellips2ned {navigation}

Transform position from ellipsoidal to NED coordinates

Description

Transform position from ellipsoidal coordinates to a fixed Cartesian NED frame

Usage

X_ellips2ned(x, x_o = NULL)

Arguments

x

An object of class trajectory in "ellipsoidal" system or a matrix of position data with latitude, longitude, and altitude

x_o

Origin of the fixed Cartesian NED frame expressed in ellipsoidal coordinates

Value

An object of class trajectory in "NED" system or a matrix of position data with x_N, x_E, and x_D, according to the type of input x
