Thanks for these interesting comments. I dunno exact details 
about RSA's use in GPS', and I know absolutely nothing about 
the architecture of GPS' PKI, etc.; that Princeton PowerPoint 
is my only source of knowledge about RSA's use, so it is nice 
to read the more educated speculations of others.

An article which elaborates on the topic, citing Lockheed Martin, 
also a target of ComodoHacker, as the drone manufacturer (DE):
