On August 16, InformNapalm published an investigation  with the first photo evidence confirming multiple reports of the presence of the Russian SPR-2M Rtut-BM jammer system in Donbas.
The readers of informnapalm.org contributed to the investigation helping us to define the exact location of the SPR-2M Rtut-BM station. The photos were found to have been made in Donetsk, in the area of Topaz plant (48.0302113, 37.7560857 ).
The geo referencing was performed by Oles Kolomiets. 
Having analyzed the satellite images from open sources, InformNapalm volunteers also confirmed the location of theSPR-2M Rtut-BM station at the ruined building.
Here are the satellite images in chronological order from 2015.
10/01/2015 – this is the last picture in which the SPR-2M Rtut-BM is visible. Therefore, from June to October, the station remained in the same position. Also in the picture, a power supply unit is visible with transmission antennas belonging to another type of Russian equipment – R-330Z Zhitel  jamming station repeatedly spotted in Donbas (marked with a green arrow).
