Cannot find Paul Riseborough, “GNC Solutions Small UAS State Estimation” Training presented to ARWORKS, 2017, important for my reseach

Hi everyone,
I am Youssef Telha. I am a sensor fusion reseacher at the RWTH Aachen, Germany. I found many citations for the forementioned resource, but I could not find it?
Can any help me find “Paul Riseborough, “GNC Solutions Small UAS State Estimation” Training presented to ARWORKS, 2017,”.

Kind regards,
Youssef
