[time-nuts] Loran C returning to a station near you...

[Magnus Danielson]

Hi,

There is indeed investigations going on about what the cost of receivers 
would be etc. A benefit of Loran-C is that relative jamming/spoofing 
resistance can be had without the need of opening up for keyed 
receivers. This helps for non-military and non-government operations. 
Now, there is tamper-proof GPS receivers that can use the keyed signal 
for increased signal stability, but I wonder to what degree they are 
deployed. Then, naturally the military can have use for these receivers. 
Work is in progress, but we do not yet know the outcome, but they do ask 
about what it would cost and what performance one would get. It will be 
interesting to follow.

While LORAN-C is "sold" as jamming/spooing resistant, that is based on 
the assumption that nobody would raise a 200 m tower undetected. True, 
but we now know that it was done for that purpose. The safety is 
relative, in that it takes quite a bit of more infrastructure compared 
to the jamming of GPS, and that lies in the wavelength of the signal 
than anything else.

Cheers,
Magnus
