Direction Cosine Matrix ECEF to NED

Formation of the conversion matrix from ECEF to NED.

direction cosine matrix ecef to ned

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

DCMef - 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.
