Hands-on session on SPICE.

Exercice 6.

You are interested in using HRSC images to find rovers in Mars. Propose a pseudocode algorithm that finds out whether the resolution of the SRC sensor of HRSC if good enough for the task.

Solution.

1. Find the position of MEX for a ET you choose.
2. Calculate the boresight of HRSC in the HRSC frame.
3. Transform the boresight to the MARS IAU frame.
5. Calculate the distance between MEX and the intersection of the boresight in the Mars surface.
6. Multipying the distance by the number of radians per pixel for SRC will give its pixel resolution.
