LORAN would be easy but it appears the USG doesn't want to fund it. It's still unidirectional and could suffer similar spoofing attacks as GPS, though this seems less likely. This article describes a sort of bi-directional LORAN alternative that would support encryption and uses inexpensive OTS components.
- davismwfl 7y agoYea, the reference in the article is what made me think of when we used LORAN out on the ocean. I learned to navigate the ocean using only a compass and LORAN, which while imperfect was always good enough to get us where we were going. I think a system like LORAN could be revisited with some encryption and not take a huge investment, the only problem is I am not sure the cost would be worth it given the likely limited range to being near coastal only. Doesn't solve the problem of crossing an ocean and wanting solid, reliable positional accuracy for emergencies etc.
