Hello Purnanand, Could you show us how you are specifying your spacecraft's initial attitude conditions ? Thanks, |

Hi Ben, I'm setting the initial condition in the function configure_initial_conditions in the example script scenario_OpNavAttODLimb.py :
def configure_initial_conditions(self):

Hi Purnanand, I've used your initial MRP in the scenario and the spacecraft attitude looks good, at least until 1 minute into the simulation. Beyond this point, there appears to be in a snag in the Vizard file that causes the vizualizer to hang, I have not had the time to explore why yet and probably won't. Moreover, i've attached the spacecraft attitude from a one hour long simulation span. The states do look smooth. What led you to believe that the spacecraft attitude was not preserved ? Finally, note that you can get the DCM using BSK's rigid body kinematics functions :

Hi Ben, You're right. Thank you very much for confirming this. I must have missed something during my first few attempts. I have a few more questions about the OpNav capabilities in Basilisk/Vizard: Best, |

Hello,
I am a new user of basilisk/vizard and am trying to learn the software and evaluate its capabilities. I am trying to manually set the initial MRP of the spacecraft in the opnav screnarios (scenario_OpNavAttODLimb.py) such that the simulation begins at t=0 with the camera pointed at the central body. However, the spacecraft is immediately rotating away from my initial condition. This behavior is not observed in other (non-opnav) basilisk simulations, where my mrp calculations precisely orient the spacecraft camera at the central body. Can you point me in the right direction?
Thank you so much!
Purnanand
