Function navtk::navutils::C_n_to_e_to_wander

Function Documentation

double navtk::navutils::C_n_to_e_to_wander(const Matrix3 &C_n_to_e)

Extract the wander angle from the N frame to E frame DCM \(\textbf{C}_\text{N}^\text{E}\).

When latitude is at or very close to +/- pi/2, the wander angle is set to 0 (as it becomes undefined).

See also

Coordinate Frames for the definitions of the N and E frames and how the wander angle is defined. This tutorial also shows how the wander angle is calculated from the \(\textbf{C}_\text{N}^\text{E}\) DCM.

Parameters

C_n_to_e – The DCM that rotates a vector from the N to E frame: \(\textbf{C}_\text{N}^\text{E}\)

Returns

Wander angle (radians).
