Rangefinders and Drones | Everything You Need To Know (2020)

Rangefinders are a very important component for drone applications. Most drones estimate altitude with a barometer, that correlates changes in pressure to changes in altitude. However, this method of altitude estimation is prone to becoming less accurate over time via a phenomena called "barometer drift". Rangefinders can be used to more precisely obtain the distance from the ground to the drone, translating into smoother flight in particular flight modes. On top of that, some drone functions require rangefinders to even work- things like precision landing and optical flow. ----------------------------------------------------------------------------------------------------------------------------------------------- If you want to learn more about rangefinders, how to install them and use them with precision landing, check out this course - --- ------ https://dojofordrones.com/drone-delivery-and-precision-landing-course/ ------ --- -
