Magnetic Moment of a Satellite and Hysteresis Rods Inclusion

Hi Julien,

You are on the right path using the magnetorquer model. Look for the function 42actuators.c:MTBModel to see how torques are derived from magnetic moments. You just need to provide your desired magnetic moment along with the other parameters. There are various ways to do this for your purposes, either populating the variable SC[i].AC.MTB[j].Mcmd (with i and j as appropriate), or setting up more calls to MTBModel customized to your situation. Go for it.

You'll have to write your own hysteresis rod model, but studying MTBModel will show you where to plug it in.

If you haven't already, I'll also suggest you familiarize yourself with the MTBType struct in Include/42types.h.

Regards,
