EclipseLocator #383

Hello, (trying to upgrade to nyx-master + ANISE 5.0) provided that I have an Almanac (possibly high precision), an earth centered frame and the sun reference frame, I am interested in determining the percentage rate of occultation of a satellite body. I already have the body's orbit figured. What is the point of using Nyx new EclipseLocator and not simply remain in ANISE, because it apparently can calculate everything that I need |

Hi Guillaume, The EclipseLocator in Nyx is mostly useful to find the start and stop times of eclipses. This is helpful when exporting a trajectory, as in this example. In general, this feature is used to analyze orbits and check that a given mission design meets the power generation requirements on a mission. Under the hood, the EclipseLocator directly calls the ANISE |

Hi Guillaume,

Under the hood, the EclipseLocator directly calls the ANISE
solar_eclipsingfunction. Therefore, if you have a fully defined orbit (position, velocity, epoch), and are looking to know whether your spacecraft is currently in eclipse (or any percentage of eclipsing), then you should use ANISE directly.
