It was developed by the designers of the space-scientific production center named after. Khrunichev. The complex will start working by the end of this year. The unique equipment is designed to detect and track falling spent fragments of the Angara launch vehicle. In turn, the aerospace defense forces intend to use it at the Kamchatka Kura training ground in the implementation of combat training launches of ballistic missiles.
The spent missile fragments fall down at supersonic speed, which is accompanied by a powerful thundering sound that spreads for tens of kilometers. Based on the recorded sound, the complex determines with high accuracy the place where the fragment falls. To do this, it measures the time difference with which the modules register the sound wave.
Operating in autonomous mode, the modules maintain constant communication via a special radio channel. Having determined with high accuracy the location of the fallen fragment, the module immediately reports this to the Orlan UAV.
The new system will be able to record up to hundreds of falling fragments at the same time, with the current rate of 4-5. Greater detection accuracy will be provided by several working stations located at a distance of 80 to 100 kilometers from each other.
