Limited GNSS signal power and changing surroundings make continuous signal tracking demanding, while demodulation of navigation data further increases receiver workload and energy consumption. Low-power IoT platforms also benefit from network connectivity, enabling collaborative multi-agent positioning, navigation, and timing without continuous operation of the embedded receiver. This preliminary study tests whether machine learning can improve IoT position estimation using shared delay-Doppler data and receiver positions.","POLITECNICO DI TORINO  \nRepository ISTITUZIONALE  \nBlack-Boxing GNSS Signals Post-Processing Through Machine Learning for Multi-Agent Collaborative Positioning of IoT Devices  \nOriginal  \nBlack-Boxing GNSS Signals Post-Processing Through Machine Learning for Multi-Agent Collaborative Positioning of IoT Devices / Minetto, Alex; Jahier-Pagliari, Daniele; Rotunno, Angela. -ELETTRONICO. - (2024), pp. 589-603.

The density of Global Navigation Satellite System (GNSS) receiver has especially increased in urban areas with the advent of small-scaled IoT devices. Due to the limited GNSS signal power and the variability of the environment, continuous GNSS signal tracking may represent a demanding task for receivers, which, in addition, have to perform demodulation of the navigation message to provide the user with meaningful information. Furthremore, when operated by low-power platforms, such as Internet of Things (IoT) devices, the aforementioned tasks may quickly drain the battery.
