Truck driver has GPS jammer, accidentally jams Newark airport
An engineering firm worker in New Jersey has a GPS jammer so his bosses don't know where he is all the time. However, his route takes him close to Newark airport, and his jammer affects its satellite systems. (news.cnet.com) Más...Sort type: [Top] [Newest]
Now let me get this straight: we are going to be lining up airliners full of people, into a very busy airport, on a system that can be inadvertently jammed by a $100 black market item in a random vehicle driving by? WHAT COULD POSSIBLY GO WRONG??????
And that is why the VOR's, LORAN, and the compass are still necessary!
LORAN still out there???
From what I've read, the traditional LORAN-C signals of old were phased out in 2010. However, there is development of something called LORAN data channel and eLORAN as an terrestrial alternative to GPS. Long wave frequencies as used in the LORAN system tend to be less prone to interference than those in the GPS band. Sounds like a good idea if they carry it out.
I used Loran C for marine navigation even used it to guide an "autopilot" and found it exceptionally dependable. It was mostly land based rather than satellite driven, but it worked well in the United States waters.
VORs can be jammed just as easily. In fact, the frequency range for VOR is immediately adjacent to FM radio. Any navigation system based on radio waves is subject to interference, be that natural or man-made.
I enjoyed FM radio entertainment through one of my VOR receivers many times when I was flying small planes locally out of HFD. Early morning flights to and from Long Island were a little more pleasant and didn't require an additional receiver.
