I. Product Introduction

The MS155FA electro-optical pod consists of long and short focal length infrared thermal imagers, a 30x continuous zoom visible light camera, a laser rangefinder, a two-axis servo-stabilized platform, and an image processing component (autonomous recognition and tracking) . It features high precision and low latency, and can be used on small unmanned aerial vehicles (UAVs) to perform day and night reconnaissance and surveillance missions over target areas.

The optoelectronic pod uses an uncooled infrared thermal imager and a visible light camera to detect, identify, and track ground targets around the clock, while simultaneously outputting infrared and visible light video in real time for mission personnel to view.

The pod has been adapted to several mainstream flight control platforms in China, enabling seamless integration with flight control systems; it can also be connected to the ViewControlStudio display and control software platform of our organization, assisting the overall unit in quickly completing the development of the UAV system.

This optoelectronic pod is mainly used in scenarios such as reconnaissance, guidance, border patrol, personnel search and rescue, and forest fire prevention.
