Description

The Direction Cosine Matrix ECEF to NED block generates a direction cosine matrix for the transition from the Greenwich rectangular coordinate system (The Earth-center, Earth-fixed (ECEF) system) to the local North-east-down (NED) tangent coordinate system (The north-east-down (NED) system) based on the geodetic latitude and longitude .

The transformation matrix has the form:

Ports

Input

μ l - geodetic latitude and longitude
`vector 2 to 1

Geodetic latitude and longitude, deg. It is recommended that the values do not exceed the ranges [-90°, +90°] and [-180°, +180°] for latitude and longitude respectively.

Data types: Float64.

Output

DCM_ef - conversion matrix
3-by-3 matrix

The matrix of directional cosines for the transformation from the Greenwich rectangular coordinate system to the local tangent coordinate system North, East, Down.

Data types: Float64.
