So, according to our calculation of filling the waste paper gap, how did this cool UAV light show come about?

-- how did the unmanned aircrew transform various dance steps

"we use two computers to control 800 UAVs." Wang Yajun said that the timing of each dance step of the UAV formation is calculated in milliseconds. After repeated motion simulation, each time node is accurately grasped. Array transformation, light change and flight rhythm are closely linked throughout the whole process, presenting wonderful visual feelings to citizens and tourists in a limited time

-- will there be a risk of collision when 800 UAVs lift off at the same time

"this will hardly happen, because we use the current domestic advanced differential positioning (RTK) technology." Wang Yajun introduced that this technology is very accurate. The horizontal error can be accurate to 2 cm, and the vertical (height) error can be accurate to 1 cm. Each UAV has an independent IP, and the dance steps and flight routes will be set by computer programming in advance. In other words, the technical level of each UAV still lags behind that of some developed countries, which have their own dance steps and flight routes and do not interfere with each other, so generally there will be no collision

-- how to ensure the viewing effect of citizens and tourists

"work hard visually." Wang Yajun said that 800 unmanned aerial vehicles dance together in the high air, which is a large scale. In order to ensure the visual effect, each unmanned aerial vehicle maintains a distance of about 1 meter. The height difference between the highest unmanned aerial vehicle and the lowest unmanned aerial vehicle is about 130 meters, and the direction facing the Wanlvyuan is inclined to 60 degrees, trying to match the line of sight of citizens and tourists to show the dance of unmanned aerial vehicles
