NBTC Certification for UAS (Drone) and Radar-equipped UAS

UAS (Drone) and radar-equipped UAS sold or imported into Thailand require NBTC certification for their radio systems. The control and data links across the 433 MHz, 2.4 GHz, and 5.8 GHz bands require SDoC, while the onboard radar system at 24 GHz requires Class A. A drone that incorporates both requires compliance with both NBTC applications.

How NBTC Classifies Drone Radio Systems

The NBTC defines two separate application names for drone radio equipment, each governed by a different technical standard:

UAS (Drone) — the application covering control and data links at 433.05–434.79 MHz, 2400–2500 MHz, and 5725–5850 MHz, governed by the NBTC Announcement on Rules and Conditions for Radio Frequency Authorization for Unmanned Aircraft for General Use.
Radar-equipped UAS — the onboard radar system application for the 24.05–24.25 GHz band, governed by NBTC TS 1038-2564.

These are distinct NBTC applications with separate certification requirements. A drone that operates on both must satisfy the requirements for each. NBTC issues a single certificate covering all applicable technologies — where applications fall under different certification classes, the highest class applies. In this case: Class A.

Certification Requirements

Application	Frequency Band	Max Transmit Power	Certification
UAS (Drone)	433.05–434.79 MHz	10 mW eirp	SDoC
UAS (Drone)	2400–2500 MHz	100 mW eirp	SDoC
UAS (Drone)	5725–5850 MHz	1,000 mW eirp	SDoC
Radar-equipped UAS	24.05–24.25 GHz	100 mW eirp	Class A

Required Documents

For SDoC — UAS (Drone) application only:

Technical specification or datasheet including wireless communication details
Product photos
Test report from an accredited laboratory
Authorised declaration

For Class A — Radar-equipped UAS application (or combined submission):

Technical specification or datasheet including wireless communication details
Product photos
Test report from an accredited laboratory
ISO/IEC 17025 accreditation certificate and laboratory scope
Authorised declaration

Where both applications apply, the Class A requirements govern the combined submission. No physical product sample submission is required.

Indicative Timeline

SDoCApproximately 1 week from submission

Class AApproximately 5 weeks from submission

Additional time may be required if NBTC requests supplementary documents during review.
