Stable imaging is essential when a UAV operates in wind, changes direction, or follows a moving subject. The DAU80 addresses this challenge with a three-axis gyro-stabilized platform. Specifically, it provides 0.1mrad stabilization accuracy, while angular position accuracy remains at or below 0.3°. Consequently, operators can keep a subject within view and collect more usable footage. The gimbal supports yaw movement from -140° to +140°, roll movement from -45° to +45°, and pitch movement from -90° to +30°. Its maximum angular velocity reaches at least 60° per second. This range gives pilots and payload operators greater flexibility during observation.

Furthermore, the metal enclosure protects the internal electronics and supports improved EMC performance. That design matters when the aircraft carries several communication and navigation systems. The DAU80 communicates through a 232 serial port with TTL support and SBUS. Therefore, integrators can connect it with suitable autopilot and control architectures. Network video output also allows imagery to reach remote operators and ground teams in real time, depending on the wider UAV system configuration.

The visible-light system delivers 3840×2160 video at 30fps. It offers a wide 83°×53° field of view with a 3.2mm lens and a narrow 20°×11° view with a 16mm lens. In practice, the wide view helps crews understand the surrounding scene. The narrow view, however, supports more focused observation of distant subjects. This combination reduces the need to choose between broad awareness and detailed viewing before a mission begins.

The infrared channel adds another layer of information. It provides 640×512 thermal imaging at 30fps, with a 22.9°×18.4° infrared field of view and a 19mm lens. As a result, a thermal drone equipped with this payload can support heat-source detection after sunset or in reduced visibility. Similarly, an inspection team can compare visible details with thermal patterns when assessing equipment, facilities, or other remote assets. The two imaging modes work together rather than forcing operators to depend on a single type of information.

The integrated laser rangefinder measures distances up to 1200m and provides ±1m accuracy. Therefore, operators can add distance information to visual and thermal observations. This capability can support situational awareness, target positioning, clearance checks, and remote assessment. It is especially useful when a crew needs more than an image to understand the relationship between the UAV and an observed object.

In addition, the DAU80 supports target recognition and target tracking. These functions help the payload maintain attention on relevant subjects during a mission. Image compression further supports efficient transmission across a network. However, final performance depends on the aircraft, communications system, operating environment, and software integration. For that reason, system designers should evaluate the complete UAV configuration before deployment.

The DAU80 fits missions that require more than standard daylight video. For example, an inspection drone can use its 4K cameras to examine power infrastructure, facilities, and remote assets. Meanwhile, thermal imagery can highlight unusual heat patterns for closer review. Similarly, the payload can support perimeter monitoring, reconnaissance, and security patrols. Its wide field of view helps crews survey an area, while the narrow view supports focused observation.

Emergency teams can also use the combined sensor package for search missions, disaster assessment, and fire monitoring. Thermal imaging may assist with locating heat signatures or identifying warmer areas in difficult conditions. Additionally, the rangefinder can provide useful distance data during remote assessment. Because the unit weighs 280g, it leaves room for other equipment on compatible UAV platforms. As a result, integrators can balance sensor capability with aircraft endurance and mission requirements.

• UAV aerial surveillance and perimeter monitoring
• Power line, facility, and infrastructure inspection
• Day-and-night observation with visible and thermal sensors
• Search and rescue, disaster assessment, and emergency reconnaissance
• Target recognition, tracking, and long-range measurement

Overall, the DAU80 offers a balanced solution for UAV teams seeking compact multi-spectral capability. Its low weight, stabilized imaging, thermal resolution, 4K video, tracking functions, and 1200m laser rangefinder make it suitable for demanding observation tasks. Before purchase, however, confirm mechanical compatibility, power requirements, control interfaces, and network integration with the intended aircraft.
