NAVIGATION ERROR REDUCTION IN SWARM OF UAVS

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 we demonstrate a novel technique to reduce the GPS error, in a swarm of UAVs.
