GPS receivers determine location in which coordinates?

Explanation:
Your position with GPS is described in three coordinates: longitude, latitude, and altitude. Longitude and latitude pin down where you are on the Earth’s surface (east–west and north–south), but you also need height to specify your exact place in 3D space. Altitude provides that vertical dimension, usually height above the reference ellipsoid. GPS uses signals from satellites and precise timing to solve for these three coordinates, plus the receiver’s time. Time alone doesn’t tell you where you are, and any single dimension (just longitude or just latitude) wouldn’t locate you in space, so all three are needed together.
