I think it's just an XY system, with X=decimal longitude and Y=decimal 
latitude.  The origin is where the equator meets the prime meridian.  The 
range of X is from -180 to +180 and the range of Y is from -90 to +90.

If the coordinates were scaled to a linear measure (meters) then I think it 
might become a standard cylindrical projection, but I don't know which one.
