Abstract :
In this paper, we analyze the UAV datalink design with calculating link budget of long-distance (200 km) Ku-band LOS wireless link. We calculate C/N ratio of the system and compare it with the required C/N ratio, using the CCIR reports which contain calculation of free space loss for different geography and weather, respectively. It turns out that, in 4 mm/h rainy day of summer on the Korean Peninsula, in order to maintain percent reliability 90% and BER 10-5 together, link budget of uplink of the system has a lot of margin at 200 km, and link budget of downlink using the block turbo code is enough for distance 200 km. At the end, we calculate the overall C/N ratio which follows the lower one, the downlink C/N ratio which is much lower than uplink C/N ratio
