DESCRIPTION: The all new DJI Mavic:
- COMPACT SIZE: The DJI Mavic Pro folds down as small as a bottle of water, making it small enough to bring with you everywhere.
- EXTENDED TRANSMISSION RANGE: New OcuSync transmission system offers up to 4.3 miles (7km) of transmission range.
- EXTENDED FLIGHT RANGE: Fly at up to 40mph (64kmh) or for as long as 27-minutes.
- TRUE 4K IMAGERY: True 4K, fully stabilized ensures smooth footage.
- MORE FEATURES: ActiveTrack, TapFly and other smart features make professional looking video effortless.
- OBSTACLE AVOIDANCE: Obstacle Avoidance combined with sensor redundancy increases flight safety and reliability.
- PRECISE POSITIONING: Vision positioning paired with GPS and GLONASS ensures precise positioning indoors and outdoors.
- FLY-BY-PHONE: Fly-by-Phone over Wi-Fi for even easier flight.
Situations without satellite positioning can be divided into two kinds. First, satellite connectivity may be unavailable during indoor flying. Second, satellite connectivity is cut off during an outdoor flight, such as by flying under a balcony or flying from indoors to outdoors. The loss of satellite positioning makes these scenarios dangerous for new pilots or those who want to long distances.*
If the drone wants to position using satellites, its flight controller needs to gain both the current location and flight speed of the aircraft. However, if the drone needs to position accurately without GPS, flight status still need to be collected. Many drones are equipped with what is known as an Optical Flow visual positioning system consisting of dual ultrasonic sensors and a single camera. The ultrasonic sensors provide altitude information by measuring the distance between the aircraft and the landing point, while the single camera is used to calculate positioning information by capturing images below the aircraft. As ultrasonic sensors are the only measure of height, the higher the aircraft flies the less precise the data from reflected sound waves become. Accurate height positioning is therefore limited to less than 3 meters. The single camera is unable to improve height positioning accuracy and limits areas that the drone can hover stably to those that have a clear texture. The Mavic overcomes these problems through the use of dual forward vision sensors. This setup allows the Mavic to see obstacles in 3-dimensions up to 15 meters in front, increasing positioning accuracy to 2-3 times that of an Optical Flow system. It also allows the speed of the aircraft to be calculated, enabling precise hovering at up to 10 meters without satellite positioning. Dual forward vision sensors allow it to calculate its current location and speed of flight by observing the scene in front, further increasing positioning accuracy. Thanks to the precise hovering technology, the Mavic is able to automatically land almost exactly where you took off. Every time you take off, the two downward facing vision sensors record a burst of video of the ground below and pair it with satellite coordinates. When you tell the Mavic to fly home, it will return to that coordinate, match the video, and land back at your feet.
*Line of sight flight is required in some countries.
