Kosmos 2499 ( Russian Космос-2499 ) is a military, Russian satellite .

Undeclared start

The satellite was launched on May 23, 2014 from the Plesetsk Cosmodrome together with three military communication satellites of the Rodknik series. Since the launch of a fourth satellite was not initially announced, it was thought to be space debris . Due to changes in the orbit from the end of May, it became clear that it had to be a self-propelled payload , which was now designated Kosmos 2499. Something similar had already been observed in December 2013. At that time, only the launch of three Rodnik satellites had been announced, although a fourth satellite, Kosmos 2491, was on board the rocket.

Rendezvous with the rocket stage

In August 2014, the satellite significantly lowered its orbit through several maneuvers and raised it again at the end of October. As a result, the satellite approached the Bris KM rocket stage, which was still in orbit. According to measurements and calculations, the minimum distance between Kosmos 2499 and Bris-KM was reached on November 8 or 9, 2014 and was approx. 760 m. The international press then speculated that Kosmos 2499 was an experimental anti-satellite weapon . A second rendezvous with a distance of less than 30 m took place from November 25 to 29, 2014.

purpose

On December 15, 2014, the head of the Roscosmos space agency , Oleg Ostapenko , denied that Kosmos 2499 and Kosmos 2491 were weapons. According to the Moscow Institute of Physics and Technology , the satellite is testing a magnetoplasmic dynamic drive .

Amateur radio

From November 30, 2014, Kosmos 2499, as an amateur radio satellite, was transmitting telemetry signals in the 70 centimeter band on 435.465 MHz in CW with the callsign RS -47.
