Abstract

In this thesis, we congregate the security threats on UAS and suggest solutions using ADS-B device. UAS ground and intercommunication is prone to availability, confidentiality and integrity attacks. UAS communication has three layered wireless Ad-Hock network which comprises of Complex group key exchange. Loss of one layer in the Ad-hock network leads to a complete loss of communication in the network. Current UAS navigation methods include complete reliance on on-board sensors, radars and GPS. This research proposes solutions for UAS communication, navigation and collision avoidance using ADS-B. ADS-B acts as a back-up when there is a loss in any one of the trees layers in an Ad-Hock network. Integration of ADS-B along with on-board sensors gives an accurate and precise location of the UAS. ADS-B also helps in neighbor discovery which prevents collisions in small UAS
