% Estimate the orbit position using horizon measurements Assume the spacecraft is orbiting the Earth and measures n star vectors. We point the camera at the horizon. This script uses the Hipparcos star catalog for navigation. This is a method of optical navigation that is what sailors use. ------------------------------------------------------------------------ See also: Constant, ISSOrbit, Period, RVOrbGen, PlotPlanetOrbit, Mag, Unit, NavigationCamera, StarCameraViewer, LoadCatalog, RaDec2U, HorizonUnitVectors, U2Q, TimeLabl, Plot2D ------------------------------------------------------------------------
