Optical Flow sensors are used for position hold on drones. Works indoors and in low altitudes even if GPS is not available. Lidar sensors helps in altitude hold.

Optical Flow sensors are useful for maintaining drone position without GPS. Suitable for indoor and low altitudes where GPS signals are not reliable. This flow sensor also includes a lidar sensor for altitude detection. 

This sensor works the same way as an optical mouse, helping your iNAV quad maintain position without GPS! It has a working range of up to 2m, and uses a VL53L0X Lidar rangefinder along with a PMW3901 optic flow module. The sensor is connected to your flight controller via a UART.
