Local tangent plane coordinates (LTP), also known as local ellipsoidal system, local geodetic coordinate system, or local vertical, local horizontal coordinates (LVLH), are a spatial reference system based on the tangent plane defined by the local vertical direction and the Earth's axis of rotation. It consists of three … See more These frames are location dependent. For movements around the globe, like air or sea navigation, the frames are defined as tangent to the lines of geographical coordinates: • East … See more In many targeting and tracking applications the local East, North, Up (ENU) Cartesian coordinate system is far more intuitive and practical than ECEF or Geodetic coordinates. The local ENU coordinates are formed from a plane tangent to the … See more In an airplane, most objects of interest are below the aircraft, so it is sensible to define down as a positive number. The North, East, Down … See more • Axes conventions • Figure of Earth • Horizontal coordinate system See more WebTwo of those ways are the geocentric and geodetic systems. The geocentric latitude of a point is the angle it makes with the Equatorial plane. The geodetic latitude of a point is the angle made between the Equatorial …

WebThe geodetic latitude, f, of any point is the angle that "up" makes to the equatorial plane. When a differs from b, the value of f differs from that of t (except along the equator and at the poles). In this picture, the blue curve is one quadrant of such an ellipse (greatly exaggerated compared to the earth's eccentricity). WebGeographical distance or geodetic distance is the distance measured along the surface of the earth.The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.This distance is an element in solving the second (inverse) geodetic problem. ecks crime triangle
