I skipped the GPS project, because there was too much to read for me (I was only scanning through). I think the storyboard of the problem seems to explain the problem good. It looks like the sketches are more on the background if I compare it with the HP project.
It might be nice to separate your projects more with a front page per project. Like you did for your thesis project. A money shot of your project with a title (+ subtitle) and short description and design challenge. It feels more like the GPS and HP project are merging into one project.
Good luck
