How would you house rule triangulating the location of something while moving?

[Storyteller01]

I'm playing with an idea for my DS campaign, and I'd like some help (purtty please??)

The idea is combining a home made dwarven starfighter class with remote operation drones. One character can be a squadron (sort of). With the proper equipment a pilot can 'be' the craft (full brain port cybernetics).

Here's where it gets touchy. The dwarven starfighter gains the ability to location objects in space by detecting gravity with a spot check. The sense wouldn't carry over to the drone. When he uses the spot gravity trick he's going to be effectively disembodied, forcing him to figure out where he and his targets are in relation to his body.

Long winded, but hopeful it was clear. Would I handle this by upping the DC of the Spot check? Do you have other suggestions?

I have no idea what you're talking about, so my suggestion is to keep it really simple: just up the spot DC.

IMC I have a Sea Ranger/Navigator PrC who gets 'Orientation as a class ability

Orientation allows the Sea Ranger at higher levels this allows the Navigator to use the stars and other signs to triangulate the position of any location using a Survival check at DC 15+distance (measured in days-travel imc)

Not sure from yuour description if that fits but it may help...
