Inputs

lat,lon, alt: ellipsoid geodetic coordinates of point under test (degrees, degrees, meters)
lat0, lon0, alt0: ellipsoid geodetic coordinates of observer/reference (degrees, degrees, meters)
spheroid: referenceEllipsoid
angleUnit: string for angular units. Default 'd': degrees

outputs

n,e,d: North, East, Down coordinates of test points (meters)
