WebJul 17, 2009 · This visualization shows the Lunar Reconnaissance Orbiter (LRO) orbit insertion from two different points of view (i.e., coordinate systems): Earth centered inertial coordinates and moon centered fixed coordinates. Orbit trails are shown in bright colors where the orbits have been and in darker colors for where the orbits will be. At any … Webwhich is why coordinate transformation matrices are also called “direction cosines matrices.” Navigation makes use of coordinates that are natural to the problem at hand: inertial coordinates for inertial navigation, orbital coordinates for GPS navigation, and earth-fixed coordinates for representing locations on the earth. dwight muhammad
