LT and GPS allow for tracking of objects and people using satellites and receivers. The GPS system consists of 24 operational satellites controlled from stations on Earth that communicate with receivers to determine location via trilateration of distances. While useful for applications like fleet management and emergency response, GPS has drawbacks like cost and inability to track powered-down or insulated receivers.
