I am planning on flying at night, and I know that below 10m the VPS ( Visual Positioning System) starts working, but at night VPS wont work, so am wondering if at night time the drone know it night and automatically use GPS at all altitudes?

Hello there lakijs1992. Good day and thank you for reaching out. Just a friendly reminder that DJI do not recommend flying your DJI drones during low light condition as the vision sensors may not work properly. DJI suggest to choose an outdoor open area where the GPS is good with lighting condition is suitable, no magnetic interference, to fly your DJI  drone and check if all the functions are normal. Thank you and fly safe always.
