Gosh I thought we already brought this into develop |
This ensures that the transformation is active and the facet normal is rotated correctly into the spacecraft body frame

@codyallard28 @patkenneally I just ran pre-commit on the srp module fiiles, this PR should be ready to merge after the checks pass. |

Description
The computed
dcm_BB0DCM in thefacetSRPDynamicEffectormodule that maps the facet normal vectors to the spacecraft body frame needs to be transposed. The rotation of the facet normal vector is an active rotation; however the computed DCM in the module is for a passive rotation. The correct transformation is therefore the transpose of the passive rotation matrix.This bug was pointed out by @rcalaon when he was not obtaining expected results from the module. Applying the transpose resolved the issue and he sees the expected results.
Verification
The transformation is identically updated in both the module and the module unit test.
Documentation
The documentation is updated to reflect this change.
Future work
The module unit test needs to be improved. The module and documentation also needs to be cleaned up.
