Abstract
In urban contexts, the increasing density of electronic devices equipped with Global Navigation Satellite System (GNSS) receivers and complementary positioning technologies is attracting research and development efforts devoted to an improvement of the quality of life towards the smart city paradigm. Vehicular and pedestrian positioning and navigation capabilities are among the major drivers for innovation in this process. Ultra-low-cost electronics such as smartphones and Internet of Things (IoT) sensors aim at providing accurate and reliable positioning solutions through a set of promising solutions. Among these, snapshot positioning allows to remotely perform the post-processing of GNSS signals in IoT sensor networks while Wi-Fi™ ranging and cooperative positioning provide auxiliary anchors of opportunity to enhance indoor/outdoor positioning capabilities. This paper presents an innovative platform to perform a centralised testing and assessment of such positioning and navigation technologies along with a set of results obtained in the context of the European project HANSEL, by relying on current network technologies and infrastructures (i.e., Wi-Fi™ and cellular connectivity).

The issues related to the growth of the urban population are among the most important challenges of our time
A prototype hardware sensor based on a Raspberri PiTM Zero W and a RTL-Software Defined Radio (SDR) RF front end was used, controlled by the SNAP Application (SNApp) routines to manage the signal capture and transmission to the processing platform
This helps in mitigating situations where Global Navigation Satellite System (GNSS) observables are not available, as it happens due to signal blockage by high buildings, and it provides an additional degree of robustness
Summary
The issues related to the growth of the urban population are among the most important challenges of our time. The bulk consumption of non-renewable resources and emissions is occurring in urban areas. This implies that cities are the first place where innovations must guide us towards a new model of sustainable development, i.e., a development that meets the needs of the present without compromising the ability of future generations to meet their own needs [1]. This is the key meaning of urban smartness [2] and the entire city ecosystem has a key role to play to reach such a sustainable future [3,4,5,6]. A sustainable economy enables cities to make long-term investments necessary to build and maintain adequate infrastructure so as to provide effective services, develop an open social environment for citizens, and foster and support business activities, without compromising the natural environment
