Product Main Characteristics 2 3. Product Description 3 4. Product Parameter Description 6 5. Additional Information 7 CROSS STARS III—PRODUCT DESCRIPTION 2 1. Product Introduction CROSS STARS III is the drone specially designed for drone performance. Supported with the world’s leading self-developed core swarm control technology, hundreds of drones fly in the night sky form the constantly changing pictures through the color change of drone RGB LED lights and the dynamic transformation of 3D space, which like a magician plays his show lighting the sky with wisdom. 2. Product Main Characteristics ⚫ The drones carry with 16.77 million color (256*256*256) RGB lights. The drones can show different colors and different lighting modes according to the change of drone dance steps in the night sky creating the starry visual feast. ⚫ Flying operation is simplified. According to the dance step documents prepared in advance, the drones realize the automatic flight in the whole performance process and unmanned operation in the flight process. ⚫ The drone performance support two communication modes including Lora radio and WI-FI. The signal is stable throughout the flight ensuring the safety of communication. TOF, barometer integrate slow CROSS STARS III—PRODUCT DESCRIPTION 3 descent technology and optional propeller protective cover physical protection can realize the dual safety protection of the drones. ⚫ High precision GNSS positioning technology ensures the reliable and accurate position of drones flying in the sky. ⚫ The drone meets the standard requirements of different countries and reach the whole world. 3. Product Description CROSS STARS III drone adopts an integrated structural shape following design. The whole drone consists of following parts: battery weight 527g, wheelbase 240mmm, The protective cover is optional as an accessory. The whole drone can be roughly divided into the following components as the following figure: CROSS STARS III—PRODUCT DESCRIPTION 4 1. Drone body: Drone body is streamlined designed with scientific and technological aesthetics. All components are designed in an integrated way, giving consideration to heat dissipation, dust prevention and water proof. The integrated design structure ensures the flight performance, greatly reduces the weight of the airframe structure, and effectively balances the ultimate weight and structural strength. The integrated design ensures the effective flight time and reliability of the system. 2. RGB LED: With high brightness and low power LED light, the drone can realize the 256 * 256 * 256 color combinations; With highly customized design light-shade ensuring the color penetrability, brightness and high fidelity of the lamp beads; RGB can support different customized colors and flashing modes, meet the switching of different working modes such as constant light and flashing. Professional customized design creates the ultimate lighting performance system. 3. Landing gear: The supporting part of the drone which is integrated with the drone body. 4. Motor: The custom developed brushless power motor which is specially developed for swarm flying scenes. The waterproof and sand resistance motor can overcome weight and provide efficient power output for the drone. CROSS STARS III—PRODUCT DESCRIPTION 5 5. Propeller: The foldable plastic propeller can balance the power efficiency, appearance of the drone and cost. There is no need to dismantle the propeller for the overall operation, which simplifies the operation and reduces the storage space. 6. SN Label: the unique identification number of the drone, which is used for equipment management such as equipment warehousing, operation management, after-sales service, etc. 7. Battery: the battery specially matching for the drone. As an accessory of the drone supplies power to the drone. The battery adopts 18650 cells with a capacity of 3500mah. 8. GNSS Antenna: The drone has built-in GNSS module and customized GNSS antenna to realize the reliable, stable and high- precision positioning of the drone. 9. Flight Control System: The system includes swarm control system, IMU navigation system, wireless communication system, TOF altitude determination system, etc. to realize the automatic control, navigation and data communication of the drone. Among them, wireless communication includes Wi-Fi and Lora radio for redundant backup to ensure worry free communication. CROSS STARS III—PRODUCT DESCRIPTION 6 4. Product Parameter Description CROSS STARS III is specially designed for drone performance show, the whole body is small, light in weight and long in endurance. Using 4 strings of conventional 18650 cells can meet the energy supply demand and achieve the maximum endurance of 33 minutes. Flight Power: 90W Working voltage range of battery: 12v-16.8v. Nominal voltage: 14.54v During the operation of the drone, RGB lights are mixed with colors through R/G/B to realize the conversion of 256*256*256 groups of colors. The maximum power of the overall LED light is 25W. The light has 3 working states:1.Extinguish; 2. Always on; 3. Breathing light / flashing.
