Path: SCPro/Landers
% 3D lander simulation. The spacecraft has 3-axis thruster control. Ideal attitude pointing is assumed. An altimeter gives the altitude. The planet is assumed to be a perfect sphere. This demo demonstrates the bilinear tangent law for descent from a circular equatorial orbit. Things to explore: 1. For the bilinear control vary the control acceleration (nAccel). 2. Try different starting altitudes. 3. Try different planets -------------------------------------------------------------------------- % -------------------------------------------------------------------------- Copyright (c) 2013-2014 Princeton Satellite Systems, Inc.
