Info

Adding new CB’s• Create NewCbName.cb file• Edit settings appropriately– Start with a good example: Io, Ceres– DON’T use Earth, Sun, Moon as starting point– Really, DON’T use any major planet either to start• Create NewCbName folder– Put in *.cb file (and any *.rot, *.grv files too)• Place folder in CentralBodies directory• If using SPICE, add *.bsp file to STKData/Spice• Restart STK/ODTKAGIPg 32 of 40www.agi.com
Eclipse and Obstruction (LOS)• STK Objects use CB for eclipse/obstruction– Satellites can specify the eclipsing body list• Additional obstructing bodies– Specify each body as Access Constraint• Lighting in the 3D Graphics Window– Doesn’t consider eclipse– Ex.: Io appears lit while located in shadow of Jupiter• Sensor projection– Doesn’t consider obstruction– Projects to object’s CB surface (thru any other CB if need be)AGIPg 33 of 40www.agi.com
