#1. In a Satellite Assisted Navigation system (GNSS/GPS) a position line is obtained by:

• AThe aircraft's receiver measuring the phase angle of the signal received from a satellite in a know position.
• BTiming the period that is taken for a transmission from the aircraft's transmitter/receiver to reach and return from a satellite in a known position.
• CTiming the period that is taken for a satellite's transmission to reach the aircraft's receiver.
• DThe aircraft's receiver measuring the time difference between signals received from a minimum number of satellites.
