9. Ondas Inc. (NASDAQ:ONDS)
Ondas Inc. rallied for a second day on Tuesday, jumping 7.95 percent to finish at $10.05 apiece as investors took heart from a new multi-billion-dollar market potential in Europe following the successful deployment of its drone solutions to the German State Police.
In a statement, Ondas Inc. (NASDAQ:ONDS) said that its subsidiary, Sentrycs, delivered C-UAS Solutions to the German authorities in a bid to support the detection, identification, and control of unauthorized drones without jamming or kinetic engagement.
Ondas Inc. (NASDAQ:ONDS) said that the technology was engineered for the demands of modern policing such as providing precision mitigation by taking control of unauthorized drones and guiding them to predefined landing zones, identifying serial numbers and operator locations in real time, as well as enabling a comprehensive, intelligence-driven response.
