Dronelyzer MIL
Dronelyzer™ MIL is a rapidly deployable Counter-UAS system designed for temporary and forward operations. Combining long-range RF detection, high-accuracy classification, and selective reactive mitigation, it delivers reliable protection against Group 1 and Group 2 drones wherever permanent infrastructure is unavailable.
Dronelyzer Stationary
Dronelyzer Stationary is a fixed installation system designed for border control, critical and intelligence agencies to detect, identify, and track all types of Group 1-2 UAVs infiltrating protected airspace. Operating with passive RF antennas, it remains completely undetectable while monitoring UAS and FPV drones within a 5-mile radius with 99.99% accuracy. The system delivers real-time analysis of multiple drone signals simultaneously, providing unmatched situational awareness and reliable threat disruption in high-risk environments. The system is scalable and compatible with other sensors such as: radar, acoustic, EO/IR and acoustic.
Dronelyzer Vehicle
Dronelyzer Vehicle provides fully autonomous protection against UxS that threaten all types of frontline vehicles - from armored units to medical and supply transports. The system can be installed on the patrol vehicle to warn a team of the presence of threat. The system automatically detects multiple UAS targets within 300 - 2000 ft, alerts the crew with visual and audio indicators, and activates its reactive jammer for a pre-set cycle without any operator input. Designed for hands-free defense, it ensures continuous vehicle and team protection while minimizing power consumption and operator workload. Compact weight and size and moderate power consumption allows for usage at practically any vehicle.
Dronelyzer Mini
Dronelyzer MINI is a small sized RF detector, that can be used with any phone, laptop or as is to scan RF environment for presence of Group 1-2 UAS and FPV drones. Also it allows to convert existing barrage jammer into advanced reactive jammers, enhancing protection for both stationary and mobile platforms. It safeguards vehicles, facilities, and critical infrastructure from UAS and UAV threats, including weaponized drones and reconnaissance missions. Fully autonomous and compact, it delivers intelligent, real-time defense against modern aerial attacks. Compact size and light weight with high accuracy allows to be carried anywhere, with powering from phone, laptop or by external power source.
Dronelyzer Software
Dronelyzer™ Software is Cold Sky Tech's embedded signal-processing core, purpose-built to detect and classify unmanned aerial systems (UAS) in complex RF environments with 99.99% detection accuracy. Operating entirely at the edge, Dronelyzer™ enables reliable drone awareness in contested, disconnected, and mission-critical environments where traditional network-dependent solutions are not viable.
CST DF-210
DF-210 is a high-precision cellular direction finder designed for permanent installation in secure facilities. Delivering accurate Direction-of-Arrival estimation across a wide frequency range, it enables reliable localization of unauthorized mobile phones—especially when paired with an IMSI catcher—making it a critical tool for correctional and high-security environments.
