TL;DR
A Lithuanian startup has introduced an open-source drone detection network that leverages volunteer smartphones to identify Shahed-type drones. The initiative aims to create the largest civic acoustic drone detection system in the Baltic region, with plans to expand across neighboring countries.
A Lithuanian startup has launched an open-source drone detection system that utilizes volunteer smartphones to identify Shahed-type drones, marking a significant step in regional security efforts. The initiative involves a network of users contributing acoustic data to detect and locate suspicious drone activity.
The project, led by the Mainline startup, involves volunteers connecting unused Android smartphones near windows, which run an app analyzing ambient sounds for low-frequency signatures characteristic of Shahed drone engines. When a suspicious sound is detected, the system cross-references data from multiple devices to estimate the drone’s location, according to a press release from the Drone Rada initiative.
Currently, the project involves 20 specialists and partners from the Lithuanian Artificial Intelligence Association, the Baltic Institute of Technology, and the Lithuanian Riflemen’s Union. The organizers aim to recruit 10,000 active users to expand the network across the Baltic states and Poland, aspiring to build the largest civic acoustic drone detection system in the region.
Future plans include integrating audio data from surveillance cameras and potentially collaborating with Lithuania’s major mobile network operators to install sensors on telecommunications towers. The team emphasizes that user privacy remains a priority, with efforts to identify drones using minimal data.
Implications for Regional Security and Civic Engagement
This initiative represents a novel approach to civilian-led drone detection, potentially enhancing security against unauthorized or hostile drone activity in the Baltic region. By involving ordinary citizens and leveraging open-source technology, it could set a precedent for community-based surveillance systems. The project also highlights the growing role of artificial intelligence and acoustic sensing in modern security infrastructure, though privacy concerns and the system’s accuracy remain under evaluation.

Background on Drone Threats and Detection Technologies
Recent years have seen increased drone activity in the Baltic region, with concerns over unauthorized surveillance and potential military threats. Existing detection methods often rely on expensive radar systems or specialized sensors, limiting widespread deployment. The Lithuanian startup’s open-source approach aims to democratize drone detection by utilizing everyday devices, building on the trend of civic participation in security measures.
Previous efforts in drone detection have focused on military or law enforcement applications, but civilian-led networks like this are emerging as cost-effective supplements, especially in areas with rising drone activity and limited infrastructure.
“Our goal is to connect these sensors into a common network that would provide an additional layer of security for society and strengthen the country’s resilience.”
