The effect of the atmosphere would be to cause drag on any ship flying
through
it. A simple method would be to apply a force to each ship that starts
in / ends
in / passes through (your choice) the atmosphere. This force would
applied
directly against the ship's final vector for the turn (so would be
applied once
all of the rest of the ship's movement is complete). It would be
proportional to
the speed of the ship (eg if ship's overall speed <= 6, force = 1,
ship's speed
7-12 then force = 2 etc).

Apply the gravitational forces for each planet separately as if they
were simple
point masses, and you won't then need to produce a map of different
gravity
zones.
