The accident of the Fregat upper stage was recorded by the military observation complex.
The detection of an emergency situation was provided by the Krona laser-radar complex for recognition of space objects.
A newspaper source in Roscosmos confirmed the receipt of data from the military department.
The Defense Ministry noted that this was the first "combat" test of the new element of the Russian space monitoring system.
He explained that the failure of the upper stage occurred “after leaving the zone of visibility of Roscosmos ground stations”, and that relaying equipment through the Luch satellites is not provided for.
The manufacturer of equipment for the complex is the company "RTI System". They explained that now the complex consists of two "nodes". One of them is located in the Caucasus, the second - in the Far East (recently commissioned).
"Krona" is part of the 821-th Main Center for the exploration of the space situation. This system combines radar and laser-optical means of monitoring space.
“The radar station constantly monitors the sky sphere, tracking all available objects. When detecting a new, its characteristics and flight parameters are determined. According to this data, a laser locator is induced on the object. The reflected signal arrives at the receiving optical telescope. Thus, the shape of the orbiter is determined. Its image and parameters are analyzed to determine the purpose of space technology, ”the material says.
