1. Yes, multiple miners on a ship stack.
2. In SE4 you could put all 3 types on an asteroid field and it worked perfectly fine, so I'm assuming you can do the same in SE5.
3. Robo miners consume lots of supplies; however, they do continue working even after supplies are drained. So you won't have to worry about resupplying your robo miners, but if you ever need to move them to avoid enemy ships, you will have trouble with that! (Of course, since asteroids - at least in Balance Mod - provide some level of sight obscuration, you won't have to worry about that until the enemy deploys advanced sensors! A fact I took advantage of during my KOTH game against you to stave off defeat a bit longer )

Note that in SE5, unlike in SE4, it appears you need a spaceport in a system in order to mine there! (Though I could be mistaken...)

The power of the ancients is now yours to command. You are truly the Master... of the obvious

Unless you have FQM and then they have small planetoids in the belt

I'm not positive, but I don't think you need a spaceport... Can someone confirm or contradict this?

Javaslinger

No you do not. Or at least I haven't had to have one. I could be wrong though.

I asume that it all depends on the question if you are a natural merchant or not.

I don't think Robo-stuff needs to have spaceports in the same system...even if you aren't a natural merchant...tho I'm at work and so can't check!

I tested this last week in a stock SP game that I am playing. I did not need a space port to receive the minerals, and I am not playing a natural merchant. I simply deployed my 5 mining satellites, left them alone, and checked the Remote Mining line for my Empire Resources.

remote extraction components dont need a space port and you can have as many of them of any combination of the three types on a ship or base and they all work and stack.

What you cant do is have multiple ships or bases working the same location

Don't forget to compare your maintenance costs against your mining production? otherwise you will be running your vessels at a loss?

Old truth, but maybe someone does not know:
Satelite group is considered one ship when applying rule that only one ship can mine from one hex.

not sure on that and I have a nasty feeling that they dont. Sataerlites are also individualy a bit small even the max tl large ones

A Satellite group is considered one ship in this case.
I tried that out. The Empire had no other significant income and did not run out of resources.

interesting have to try that

I have long wondered why people even bother with mining ships and mining bases... the first are inefficient, while the second are hard to research then build...

The sats, on the other hand, only require a 110 kT sat which is pretty cheap to research (lvl4: first medium sat in BM), can be built on any planet, are very efficient (maybe even more than bases, have to check that...) and can be easily redeployed (while the ship will run out of supplies and the base has to be scrapped).
Oh, and you can have any number of them in a asteroid field, opposed to only one ship/base.
You only need sat launchers to maintain them, sat launchers who can already be used as cargo transports and mantaining warp point defenses (which will be better with better sats!)

Maybe they are a little bit overpowered right now...
