LightPath Technologies and Picket Defense Systems Partner to Integrate CST Solo Infrared Sensing into Inferno RTC Counter-UAS Platform
LightPath Technologies and Picket Defense Systems have announced a partnership to integrate LightPath's CST Solo passive infrared sensing technology into Picket's Inferno RTC close-range counter-UAS system. The CST Solo employs a shutterless algorithm to deliver uninterrupted passive infrared awareness, eliminating the detection blind spots caused by traditional infrared camera calibration cycles — a critical advantage against high-speed FPV and AI-enabled drones.

Highlights
- LightPath Technologies and Picket Defense Systems have announced a partnership to integrate the CST Solo passive infrared sensor into the Inferno RTC close-range counter-UAS platform.
- The CST Solo uses a proprietary shutterless algorithm that combines multiple infrared focal plane arrays into a single imaging engine, delivering uninterrupted passive infrared sensing without calibration-induced blind spots.
- Eliminating sensor blind spots during calibration cycles is identified by both companies as a critical advantage against high-speed FPV drones in close-range engagements.
- The integration of passive infrared sensing into the Inferno RTC system enhances threat detection, identification, and continuous tracking without emitting radar signals, reducing the system's electromagnetic signature.
- The partnership targets the growing threat from FPV and AI-enabled unmanned aerial systems in tactical close-range defense scenarios.
LightPath Technologies and Picket Defense Systems Join Forces to Enhance Counter-UAS Infrared Sensing
U.S. companies LightPath Technologies and Picket Defense Systems have announced a partnership to integrate LightPath's CST Solo passive infrared sensing technology into Picket's Inferno RTC counter-UAS (C-UAS) platform.
Technology Integration Overview
Under the agreement, the CST Solo sensor will be embedded into the Inferno RTC system, combining LightPath's passive infrared technology with Picket's close-range drone defense capabilities to address threats posed by FPV (first-person view) and AI-enabled unmanned aerial systems.
CST Solo Shutterless Technology Advantages
The CST Solo system integrates multiple infrared focal plane arrays into a single imaging engine and employs a proprietary shutterless algorithm.
Unlike conventional infrared cameras, which briefly interrupt image capture during their calibration (non-uniformity correction) cycles, the CST Solo's shutterless design delivers continuous, uninterrupted passive infrared awareness — eliminating the momentary detection blind spots that traditional sensors produce during recalibration.
A Critical Defense Consideration Against High-Speed FPV Drones
Both companies highlighted that eliminating calibration interruptions is particularly important when countering high-speed FPV drones. In close-range engagement scenarios, even a brief sensor blackout can be exploited by an incoming FPV drone, creating a dangerous gap in defensive coverage.
Enhanced Detection and Tracking with a Reduced Electromagnetic Signature
According to LightPath and Picket Defense Systems, integrating the passive infrared sensor into the Inferno RTC platform is designed to improve the system's ability to detect, identify, and continuously track aerial threats — all without emitting radar signals that could be detected by adversaries, thereby significantly reducing the system's overall electromagnetic signature.
