			b) moveable object "distance" to the next globe coord in game ticks (distance / speed).
			Field_8 is fractional part of distance (distance % speed).

			I think I've found what this field_8 is and what these 5400/7560 values are.
			This is a fractional part of latitude/longitude coordinate which is accumulated when craft is flying (this is omnidirectional value of how much craft moved away from "grid" center). Say, 2880 units is whole 360 degrees (along equator). 8 units per one degree... That's too much really. So they've splitted up this coordinate grid into "subgrid" 5400 units long and 7560 along diagonal (1/1.4, quite close to 1/sqrt(2)) and logically connected with craft speed units.
			Thereby craft move from (300,300) to (302,303) will take 2 straight moves and one diagonal. Maximum craft speed is...? Right, 5400! So this craft will be flying right 1/8 degree per 1 game frame (which is 5sec). Slower crafts will require more game frames to fly through 1 xcom geographic unit.
