A three‐dimensional ray‐trace program developed by ITSA, Boulder, Colorado is compared for range accuracy with theoretically calculated values of range. Ray tracings were made through two quasi‐parabolic ionospheres of different heights and thicknesses with no magnetic field or electronic collisions involved. For the case where the maximum allowable single step error was a minimum (corresponding to longer computer running time), the maximum range error encountered was 26.3 km at a zero‐degree launch angle. However, for launch angles equal to or greater than 0.5°, the typical range errors were less than 1.0 km.
