CONT

The ground station equipment error is mainly the octantal error in the installations using two antenna pairs and a rotating goniometer for obtaining the rotating figure-of-eight pattern. Octantal error can also arise owing to in homogeneity in the ground characteristics at the installation and could, therefore, occur even where rotating antennas are used.
