Phantom 4 specifications

[Reem_]

Hello guys! I hope you are doing well. I'm kind of beginner and I've a silly question regrading the specifications.

"The Phantom 4 drone is chosen as the platform, since it includes a better safety system and ultrasonic height sensor, compared to the older versions in the Phantom series. The improved ultrasonic height sensor provides a reliable height measure that is used throughout mission execution to make altitude adjustments."

Is it correct to say this about phantom 4?

Is it correct to say this about phantom 4?

The ultrasonic sensor has a range of only 10 metres so is only used close to the ground.
Beyond 10 metres the drone uses a barometric sensor to maintain altitude.
