One major major major problem that Russia has is their lack of optical satellites. They only have 3 operational optical recon satellites remaining: the recently launched (March 2022) BARS-M, then Persona 2 and 3. All their other satellites like the EMKA series decayed out of orbit and weren't replaced, or failed.
This is nothing. Russian Space Forces are asleep or something. For comparison, China has the civilian Jilin-1 constellation with 75 full sized (1+ ton, <1 m resolution) optical satellites.
If Russian forces are not buying satellite imagery from China, they have to start yesterday. It is no wonder Ukrainian forces are achieving operational surprise.
They achieved operational surprise by using the oldest trick of the book. Bad weather. No airplane, no drone, no satellite. No aircraft to attack you nor can artillery get to you. However it also means everything will turn to mud.
