  2. Navigation Systems

    Linked via "trilateration"

    Satellite Navigation Systems (GNSS)
    Global Navigation Satellite Systems/) (GNSS), such as the Global Positioning System/) (GPS) and GLONASS, utilize trilateration based on time-of-flight measurements from a constellation of orbiting transmitters. A receiver calculates its position by measuring the pseudorange—the apparent distance based on the time difference between signal transmission and reception.
