UAV Electromagnetic Compatibility (EMC) Testing: The Invisible Guardian of Flight Safety

EMC Testing: The First Step Toward Compliance and Safety for UAV Products
In today’s rapidly evolving UAV industry, from consumer-grade aerial drones and logistics transport drones to specialized military and police UAVs, products must not only deliver flight performance and payload capacity but also meet the stringent electromagnetic compatibility (EMC) requirements set by various countries and regions. EMC is not just a regulatory requirement — it is a key indicator that ensures stable UAV operation, prevents communication failures, and guards against electromagnetic interference.

Professional Testing Based on UAV Category
SGS EMC Lab is one of the primary BSMI-accredited Lab, and also CAA-recognized testing laboratory for UAVs. Different testing modes and parameters are applied for drones under 2 kilograms and those over 2 kilograms. At the same time, SGS supports international standards such as CE and FCC, helping products enter global markets with confidence.

Comprehensive Test Scenarios That Accurately Simulate Real-World Conditions
The SGS EMC laboratory uses a variety of test scenarios to precisely simulate UAV operational and charging states in real-world applications, including:

• Radiated Interference (Operating Mode): Simulating radiation effects when the UAV activates functions such as GPS, photography, or Wi-Fi during flight. Tests require suspending the UAV in the air and operating it under both “standby” and “heavy load” (high-speed rotation) conditions.
• Conducted Interference (Charging Mode): to examine whether the conducted interference levels of a UAV or its remote controller during charging - to prevent from affecting other devices .
• Accessory Testing: Remote controllers and joysticks with built-in lithium batteries are also included in the testing scope.

Electronic Fence Map System Verification for Aviation Law Compliance
According to Taiwan’s new Ministry of Transportation regulations, starting in 2025, all UAVs with map display functions must submit separate map system test reports. SGS offers testing solutions aligned with the “Remote-Controlled UAV Management Regulations,” covering geographical zones including the north, central, south, east, and Fujian (Kinmen County), verifying whether UAVs can accurately display restricted or no-fly zones and issue alerts through on-screen messages, sounds, or light signals.
