Both local (relative to the grid that is parent of the subgrid the brick is on) and global (actual world position/rotation) variants.
The gate would also have a boolean to decide to either report position of "center of mass" of the grid it is on or the brick that has this component/this gate position.
Use case would be minimaps, race lap tracking, etc., basically anytime you want to know something's position.

also, getting the position of another grid (via read brick grid) relative to the position of this gate,
or some other way to be able to choose a point to measure relative to, by placing a gate down as a marker
e.g. one gate is on a car, another is on the center of a race track
or even have the measurer gate have two position or brick grid entity inputs and then you can keep your logic elsewhere from the position markers
