GB/T 38909-2020Electromagnetic compatibility requirements and test methods for civil small and light unmanned aircraft system (English PDF)

1 Scope

This standard specifies the electromagnetic compatibility requirements for civil light and small UAV systems (including aircraft and ground stations, hereinafter referred to as UAV systems)

And test methods, including electromagnetic emission and immunity test items, test requirements, test conditions, test equipment, test methods and test reports.

This standard applies to the design, manufacture and testing of civil light and small UAV systems (take-off weight between 0.25kg and 150kg).

Other types of UAV systems can also be implemented by reference.
