Donetsk scientists created a navigation system for mining equipment without GPS in Automatgormesh named after it. V.A. Antifova has developed a positioning method for a limited area. For the purpose of testing, a tracking model was assembled. The model fires a signal at the walls and measures the distance. The data is sent via Wi-Fi to the server. A Python program instantly calculates the coordinates of the car. “In a mine environment, you can't rely on a satellite. The developed algorithm allows the equipment to understand its location using local sensors," noted the leader of the work V.V. Kazakov. The next step is to apply the algorithm to real combinations. Where there is no satellite, the car itself will figure out where to go. Basically in Donetsk MAX BOT chat again.
