Solar Panel Illumination

Postby pselves » Mon May 18, 2020 11:09 am

Hi,

I'm trying to use GMAT to find the illumination conditions of body-mounted solar panels on a CubeSat. At the moment I'm assuming the method would be to find the direction vectors of each face of the CubeSat, along with the sun vector, so that the angle between them can be calculated, leading to an effective illuminated area on each face.

However, I am pretty new to GMAT and I can't seem to figure out how to obtain these vectors, which coordinate frame to use, whether I need a .3ds model of the CubeSat etc...any help or pointers in the right direction would be much appreciated :)

There might also be an easier way of calculating effective area of solar panels than what I am attempting!

Many Thanks
