I have recently been using aerial photography to correlate ULS-listed lat/long of some part 101 things where they really are.
I have found a lot of glaring errors where the z/y coodinates are off by 50 meters or more, on new links. Nowadays this is in my opinion inexcusable, a $300 smartphone on a rooftop or hilltop will see ten GPS satellites and four or five GLONASS satellites. Everything I've put up recently is accurate in x/y/z dimensions to 2 meters or less, including the AGL figure. > On September 24, 2015 at 5:50 AM "Hardy, Tim" <[email protected]> wrote: > > > Typical example of the many errors one can find in ULS and why it’s a bad idea > to use this data for interference analysis / coordination.
