Conference Paper
In this paper, we investigate the effects of spoofing attacks on the mass-market positioning and navigation units integrated in modern day Android™ smartphones. In order to operate spoofing in a real environment, we designed and implemented a portable, configurable, low-cost GPS spoofer exploiting a software-defined radio (SDR) implementation and a...
Conference Paper
The combination of ubiquitous network infrastructure and the high density of powerful, interconnected mobile devices in urban areas is driving the rise of smart cities. In parallel, the availability of ultra-low cost embedded Global Navigation Satellite System (GNSS) has enabled several affordable Location Based Services (LBS). New chipsets support...

Raw Global Navigation Satellite System (GNSS) measurements have been available since 2016 in select Android smartphones. The availability of such observations allows smartphones users, in principle, to significantly improve the quality of GNSS-based positioning by applying customized and advanced positioning algorithms. However, the quality of such...
The use of multiple GNSS constellations has been beneficiary to positioning performances and reliability in recent times, especially in low cost mass-market setups. Along with GPS and GLONASS, GALILEO and BDS are the other two constellations aiming for global coverage. With ample research demonstrating the benefits of GALILEO in the European region...
Global Navigation Satellite Systems (GNSS) technology has been a consistent alternative to monitor and detect structural deformation using geodetic receivers. The role of low cost GNSS receivers have been explored in recent years and this study proposes the use of two such receivers as master and rover respectively to detect fast deformations. Sing...

Today, many of the location-based services (LBS) related to urban mobility rely on smartphones. The availability of raw GNSS measurements on Android phones has opened up the possibility of exchanging such measurements for improved accuracy, precision, robustness, and availability. Collaborative ranging and cooperative positioning (CP), if implemented with the smartphones’ ultra-low-cost GNSS chipsets, can enable a plethora of applications that support a modern smart city framework. Cooperative Android Positioning System for Localisation (CAPS-Loc) proposes developing an optimal framework on Android smartphones for the exchange and nearreal-time exploitation of raw GNSS measurements, as well as improved LBS. It is slated to provide three key functionalities: A network structure for the real-time exchange of measurements, one white box for the combination of measurements by means of time synchronisation, and a second white box for the integration of collaborative data into the main navigation algorithm. Aside from being a server-based system, CAPS-Loc is expected to use a phone-to-phone mode based on Wi-Fi direct to ensure continuity of its service when no network is available.
