Which calculation on lat/lon coordinates would make an atom-scale error grow, say, a million times to millimeter-size?

    You joke but a lot of radar/radio observation is done with ECEF coordinates, which is a (lat, lon, z-axis) triple.

      ECEF is a Cartesian (x,y,z) not spherical (𝞺, θ, 𝜑) coordinate system. Units in ECEF are in meters from (0,0,0).

        Blah, shows how much I remember about it. We always converted to ENU locally to start with, hah.
