Detection and jamming sit in different legal boxes
Many regions allow any site owner to monitor the RF spectrum, but reserve jamming and GNSS deception for police, defense, aviation, or licensed critical-infrastructure operators.
Authorization usually involves more than one agency
Spectrum regulators, aviation authorities, and interior or defense ministries may all have a say; procurement timelines should include licensing lead time.
Export control applies to buyers and suppliers
Counter-UAV equipment is frequently export-controlled; end-user certificates and re-export restrictions are standard parts of a compliant purchase.
Document everything
Event logs, authorization scopes, and operator training records protect the operator legally and are increasingly demanded by insurers.
