Mentour Pilot's latest video (on YouTube) is about navigation and the various technologies that are used. Even I can understand it.
The article is focusing on the development of quantum navigation which is in response to GPS spoofing which could also affect inertial systems which may reference GPS data to correct any errors.
JB may remember discussing nav basics over on Whirlpool and how the new kids on the block seem to think that GPS is all they need to figure out how to get from point A to B via C, D, E, F and G. The US military is once again teaching celestrial navigation given the GPS frailties.
It blows my mind when I read stories about how new tech is researched, developed and commercialised, especially when I get that self-satisfied feeling when I can figure out how to use my car's GPS to get through Melbourne without ending up in Mildura...
