    I put your data for the CelesTrak TLE and for the H-A TLE into my GPS and
    indeed, for the CelesTrak it shows that I was about 0.48 miles too far West
    and for the H-A TLE it shows that I was about 0.67 miles too far W, as far
    as I can tell. I'm trying to figure out how to measure distance using the
    controls on my GPSr and am finding it a bit challenging. The unit
    instructions are all but worthless.
    Thanks for the input.
