The Screenshot is a tad odd, although the cyrillic doesn't help.
When near or landed on a Moon (mapped or auto-mapped by Game Design) with one Installation (human) it should read :
- Detected Signals : 1
- Human : 1 (= that's the very Installation you're docked at)
So on such a Planet/Moon and docked at the only Installation = no action required. That Signal must be the location you're docked.
I wonder if this might be a glitch in the translation? It would be worth landing at another Planet/Moon with human installations to verify what the signal type states there.
In the English Version, "other" AFAIK indicates a Comms Beacon or Tourist Beacon (unsure).
Planetary Installations (dockable or not), close enough Outposts and Stations or Orbital Installations (various types) and Fleet Carriers should indicate and count as "human".
