Should either Grav or Geo Sensors have an EM signature? Or both? Currently, both seem to have zero.
Geo sensors would seem to be the most obvious. I guess I'm picturing some sort of ground penetrating radar or scanner working from a spaceships. Seems like that would have a pretty healthy signature on anyone running an EM scanner in the area.
Grav sensors? For game play, I'm tending towards yes. But I could picture either way. I guess I like the game play notion of a grav survey ship probing around with loud sensors looking for Jump points. Again, very noticeable to anyone running an EM scanner in the neighborhood. But I suppose I can also see those Grav Sensors being some sort of quiet passive sensors measuring tiny differences in gravity leading towards finding a jump point.
Right now, both Grav and Geo ships are rather stealthy in a system as neither sensor seems to have an EM signature. Maybe I can see Grav ships being stealthy as they probe around the edges of the system. But it seems like at the least Geo ships should be noisy as heck if they are scanning for minerals down in a planet. And for game play, I suppose my mind tends towards both being noisy, and thus both being something you really can't operate in a system where you aren't welcome.
Thanks!
