Upon landing, the battery can be automatically replaced in just 25 seconds, allowing the drone to take off again within 45 seconds. The system offers a single-mission endurance of up to 59 minutes. The included Matrice 5TD drone is equipped with multiple sensor modules, delivering mapping accuracy of up to 10 centimeters. It excels in telephoto and infrared imaging capabilities, supports a maximum payload of 450 grams, and provides three mounting positions for additional equipment. Leveraging full-link AI technology, the platform enables real-time identification of 17 types of targets and supports the integration of custom third-party AI models. Additionally, it features advanced multi-sensor systems for precise nighttime obstacle avoidance and can operate reliably in extreme weather conditions. The inclusion of a parachute further enhances its suitability for diverse mission scenarios, including power line inspections and emergency rescue operations.
