Moon Scanning Pointing

Hello everyone, i would like to implement a pointing to the moon in order to be able to scan it. The scanning would be so that if we have a rectangular field of view on earth i would like the moon to pass though this field of view in a linear movement along the accross track axis of my sensor. I was trying to see if some of orekit pointings would be useful to use them directly or combine them. Has someone some ideas for that ?

Thanks a lot
Louis
