9.3 National safety requirements
Interference constitutes disruptions to the radio controls
of GNSS of a UAS, whether deliberate or not, by other systems. In some cases,
control signals may be disrupted by other signals sent simultaneously on the
same frequency, e.g. by radio towers and transformers.
Modification concerns making technical adjustments to an
UAS. Such modifications may disrupt an operation.
