This answer to What do all these vectors point to in this New Horizons trajectory/operations simulation? begins:

The software is definitely AGI's STK (notice the font and the states at the left top corner). There seem to be two or maybe three frames attached to the spacecraft.

Sir Brian May's New Horizons music video and probably AGI's STK graphics

Also shown are a block of long, skinny rectangles drawn against the celestial sphere, and these move around as the spacecraft's attitude changes.

Question: What is this block of long, skinny rectangles in this New Horizons trajectory/operations simulation?

    $\begingroup$ @Fred whatever it is, it seems to be opposite the RTG and rotate along with the spacecraft. It also turns out that LORRI is opposite the RTG and rotates along with the spacecraft. Coincidence? $\endgroup$

Those look like the instrument fields-of-view (FOVs).

Figure 7 of The New Horizons Spacecraft, Fountain et al. looks quite similar:

    $\begingroup$ They sure do! The instruments can't independently point themselves; their FOVs are permanently glued to the spacecraft's attitude. $\endgroup$
