Arrange the described GNSS position process in order: receive satellite signals; measure distances to satellites; combine the distance measurements by trilateration; determine geographic coordinates and show the aircraft on the device map.

### Why this is right The receiver must first obtain signals before it can estimate satellite distances. It then combines those distances to calculate a position and presents that result as coordinates and a map location. ### The concept GNSS position determination is a measurement process. Satellite signals provide the information used to estimate range. Trilateration combines ranges to constrain the receiver’s location. Once the position is computed, the device can display it and relate it to stored aeronautical information such as waypoints. An updated database is needed for current coordinate information used in route navigation. ### The order 1. Receive satellite signals: the receiver needs signal data before making measurements. 2. Measure distances to satellites: these measurements constrain possible positions. 3. Combine the distance measurements by trilateration: multiple ranges produce a position solution. 4. Determine geographic coordinates and show the aircraft on the device map: the calculated solution is presented to the user. ### Terms - **Global Navigation Satellite System (GNSS)**: satellite-based navigation. - **Trilateration**: position calculation from measured distances. - **Aeronautical Information Regulation and Control (AIRAC)**: the aeronautical information database cycle identified in the material. ### Remember Signals first, ranges second, position calculation third, map display last.
