Transform position from NED to ellipsoidal coordinates

Transform position from a fixed Cartesian NED frame to ellipsoidal coordinates

X_ned2ellips(x, x_o = NULL)

Arguments

x

An object of class trajectory in "NED" system or a matrix of position data with x_N, x_E, and x_D

x_o

Origin of the fixed Cartesian NED frame expressed in ellipsoidal coordinates

Value

An object of class trajectory in "ellipsoidal" system or a matrix of position data with latitude, longitude, and altitude, according to the type of input x

Examples

data("example_1_traj_ned")
traj_ned <- make_trajectory(example_1_traj_ned, system = "ned")
plot(traj_ned)

traj_ellips <- X_ned2ellips(traj_ned, x_o = example_1_traj_ellipsoidal[1, -1])
plot(traj_ellips, threeD = FALSE)

plot(traj_ellips, threeD = TRUE)
