A group of cooperative UAVs, also called a swarm of UAVs sometimes very effective for certain tasks like mapping, target searching etc. For large area surveillance, a number of UAVs are preferred. In such situation, navigation becomes a prime factor, which reduces the chance of collision. UAVs primarily depend on GPS, which has an order of inaccuracy. Conventional correction methods like differential GPS needs extra hardware and cannot improve stochastic errors like multipath error and receiver error. In this paper, the authors demonstrate a novel technique to reduce the GPS error, in a swarm of UAVs.
