Why did Medog Post in Tibet use drones to airdrop supplies?

Because most of the duty stations in Medog, Tibet are located in no man's land, with high mountains and dense forests and steep valleys, there is no highway so far, and the supply of materials depends entirely on the relay of officers and men on foot. On the eve of National Day this year, drones flew in with supplies. For the first time, the "Snow Island" postal service was opened to transport goods by air. Soldiers eat fresh fruits, vegetables and moon cakes.

Sergeant Qi Zhen of a frontier defense company in Tibet Military Region has served in Medog for 4 years. He introduced that for a long time, officers and men spent two-thirds of their time on unlucky roads. "From the starting point of sending materials to the first-line duty point, it usually takes 120 people to relay for 2 to 3 days. It is difficult for many officers and men on duty to eat fresh vegetables, fruits, eggs, milk and meat, basically eating dehydrated vegetables and canned food. "

This time, Qi Zhen and his comrades-in-arms ate fresh fruits and vegetables, eggs and meat, and drank milk and drinks. "In the past, we seldom ate eggs in the mountains because our backs were easily broken. Now we feel happy to eat them. The drone also sent us moon cakes, and I believe that our food will become more and more abundant in the future. "

UAV intelligent airdrop material supply

The duty station in Medog, Tibet, is a veritable "isolated island" because of the frequent shortage of materials due to geological disasters, heavy snow closure and other reasons. Every rainy season in Medog, continuous rainfall leads to frequent geological disasters such as landslides and mudslides, and it is difficult for even land and air transport helicopters to find a "window period" for flight.

On the eve of the National Day this year, the Army Logistics Department organized a number of units and used more than a dozen multi-rotor drones and unmanned helicopters to organize a real flight and verification project in Medog. According to the mode of satellite positioning, autonomous take-off and landing, intelligent cruise and fixed-point delivery, all four air routes deployed by officers and men of a certain unit of the Tibet Military Region have been opened one after another.

According to reports, the multi-rotor drone has a load of 15 to 25 kilograms, is powered by batteries, and the charging time is 40 to 50 minutes. It can last 1 hour and fly 20 kilometers with full load. This time, the drone flew back and forth between different points, ensuring continuous flight and air delivery by quickly replacing the battery.
