MS220TD Two-Axis Tri-Light Pod

The MS220TD electro-optical pod integrates a cooled infrared thermal imager, a 30× continuously zoomable visible light camera, a laser rangefinder, a two-axis servo-stabilized platform, and an image processing module featuring autonomous target identification and tracking. Designed with high precision and a long operational range, the pod is well-suited for medium and small-sized UAVs to conduct round-the-clock reconnaissance and surveillance missions over target areas.

Equipped with the cooled infrared thermal imager and visible light camera, the pod enables all-weather detection, identification, and tracking of ground targets. It simultaneously outputs real-time infrared and visible light video for mission operators to monitor.

The MS220TD has been adapted to several mainstream flight control platforms in China, allowing seamless integration with UAV flight control systems. It can also interface with our organization’s ViewControlStudio display and control software platform, helping the overall system integrator to rapidly complete UAV system development.

Typical applications for this electro-optical pod include reconnaissance, border patrol, personnel search and rescue, and forest fire prevention.
