The GPS antenna receives information from the constellation of GPS satellites in the sky. The signals are 'line of sight' transmissions i.e. there must be an unobstructed view between the satellites and the GPS antenna. The antenna is able to pick up signals through glass and non-electrically conducting trim - but not through metallic objects, buildings etc.
