All of this brings us to a very interesting Australian company called Advanced Navigation. If we fast-forward to the present, we find that the guys and gals at Advanced Navigation have expanded their footprint across the globe. I was just chatting with Matthew Suntup, who is a Senior Application Engineer at Advanced Navigation. In fact, folks at Advanced Navigation successfully demonstrated a breakthrough in underground navigation, delivering high-precision positioning without reliance on fixed infrastructure or GNSS, in one of the world’s deepest underground mines at Pyhäjärvi, Finland. LUNA is a space-qualified laser-based navigation sensor that delivers precise 3D velocity and altitude data relative to the lunar surface.
