Suranaree University of Technology (SUT) has unveiled a homegrown drone signal jamming system designed to counter espionage and security threats, which it claims costs ten times less than comparable systems on the market.

 

The system, demonstrated on the 4 September, at the university’s U-Space Technology Centre, was presented by Associate Professor Dr. Anan Thongra-ua, President of SUT, alongside Associate Professor Dr. Chanchai Thongsopa, head of the university’s Centre of Excellence in Electromagnetic Applications, and Assistant Professor Dr. Samran Santhalunai.

 

The innovation, developed by a team of Thai researchers, disrupts both GPS navigation signals (1.575 GHz) and remote-control frequencies (2.4/5.8 GHz), causing unmanned aerial vehicles (UAVs) to lose navigation and control, forcing them to hover or crash. It can be deployed either for site-specific defence or for border surveillance, with an effective jamming range of about 10 kilometres,

 

 

Colonel Sathit Oonkai, deputy commander of the 21st Military Circle, attended the demonstration on behalf of the 2nd Army Region, which plans to test and adapt the system for border security operations.

 

Field trials at Nakhon Ratchasima’s Wing 1 airbase confirmed the system’s effectiveness against both custom-built drones and commercial agricultural UAVs. According to the developers, the prototype can be produced for under 300,000 baht and built within 15 days, making it significantly cheaper than foreign-imported alternatives.

 

The device uses specialised omni-directional and parabolic dish antennas to deliver high-power interference signals, supported by an advanced cooling system for stable field use.

 

Dr. Chanchai said the development addresses an urgent need, as drones are increasingly used for surveillance, smuggling and unrest along Thailand’s borders.

 

“This innovation proves that Thai research can deliver real-world solutions for national security,” he said. “It reduces reliance on imports, strengthens military capability, and ensures Thailand can safeguard its sovereignty with technology developed domestically.”

 

The 2nd Army Region, based at Suranaree Camp in Nakhon Ratchasima, will conduct further field applications of the system to reinforce national defence.

Surely they could have reprogrammed one of the bomb detectors with a drone jammer card.
