The More Things Change…

…the more they stay the same. In the original Star Trek* episode “The Ultimate Computer,” Captain Kirk recites a line from John Masefield’s poem “Sea-Fever”: All I ask is a tall ship and a star to steer her by. What was good enough for the captain of a Constellation-class starship is good enough for modern sea captains as well, whether they be in command of merchantmen, Naval vessels, or Coast Guard ships.

GPS is indispensable these days—but it’s still incredibly fragile. It can be spoofed with a fake satellite signal, hacked by an adversary, or simply destroyed. Spoofing, hacking, or destroying the stars? Not happening.
