+   * 2. Waits for 2500 milliseconds to allow the system to collect and process NMEA strings,
+   *    which carry essential navigation data.
+   * 3. Resets the feature model's attributes to ensure feature updated.
+   * 4. Validates that the attribute values for source, quality, fix status, and satellite count
+   *    are set correctly, confirming that the positioning data has been successfully acquired.
+   * 5. Verifies that the position coordinates (x, y, z) and are now defined,
+   *    signaling that the feature model has processed the positioning data correctly.
