Abstract:	The detection and localization of GNSS jammers might be of high interest due to the increasing services and applications relying on the GNSS signals for its operation. In this context, the current evolution of cloud computing and the Internet of Things (IoT) –with future devices connected to the Internet and applications running in the cloud– together with the concept of Smart Cities, makes feasible to think about a cloud-based localization of GNSS jammers. This paper presents the cloud-based localization concept and proposes a technique for the estimation of both TDOA and FDOA measurements –which are proposed to be used in the localization process– when linear chirp-based signals are transmitted by the GNSS jammers –as it is the case in many jammers in the market– and one or multiple jammers are present in the scenario. Moreover, both static and dynamic jammers and/or GNSS sensor devices are considered in the design. The localization results obtained with the proposed technique in a simulated scenario show the potential of the cloud-based localization, in particular in the context of Smart Cities where a relatively high density of GNSS sensors could allow the precise localization of GNSS jammers.
