How do I use GeoSensor Missiles? ... and other odd questions

[NihilRex (OP)]

Do I just make the geosensor missile, load it in a ship's tube, then fire it at a waypoint, and watch the system be surveyed?  Or do I have to fire one at each system body?  If the latter, how do I make them show up in the targeting list?  (The one time I tried to just launch them and let them work automatically, they just sat there.)

Is there any way to make a fleet deploy its parasites while retaining their previous orders, like "geo survey, refuel resupply as needed," or do I have to redo that for each deployment?

Is there a "recall parasites\escorts" command I can stack in the orders list that Im missing somewhere?  (I doubt it, but worth asking)

How do I figure out the TCS1\Missile detection range of a higher resolution sensor system?

1) Fire one at each system body. There are two ways to do this. A: Give the launching ship the "launch at" order which causes the ship to fly to the body before kicking all currently loaded missiles out the hatch. B: Create a waypoint attached to the body by first clicking on the system body and then clicking the 'last' button on the waypoint tab.

2) Not sure.

3) Not really. The last time I did something like that I gave the parasites the "return to jump entry point" as a secondary default order and left the carriers/jump tenders on the jump point. The conditional order "join parent fleet" might also help, but I don't know of any command that can be given to a parent fleet to recall the offspring.

4) Missiles have a TCS of Missile_Size / 20 or 0.33, whichever number is greater. If  Target Size < Resolution, then Detection Range = MaxRange * (targetSize/Resolution)^2. For a small missile this works out approximately as 1/225th of the 250ton detection range. Practically, just assume that larger resolutions will never reliably detect small missiles.
