Secondary phase error

4-4-160

Secondary phase error (in Loran C)

Alternative term: Fixed errors (in Decca)

Those errors in the lattice as charted, due to different phase velocities over regions of different earth conductivity and dielectric constant.

These errors are defined for a given site, and are listed for each system correction for the errors can therefore be made.

Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
