Global IoT Networks as Distributed Radio Telescopes: A Feasibility Study

This paper proposes a novel approach to radio astronomy by leveraging the global network of Internet of Things (IoT) devices. The concept involves using widely dispersed IoT devices to simultaneously capture astronomical and communication signals. Digital beamforming techniques are then applied to align the astronomical signals and minimize interference from communication sources. Calibration is achieved using multiple distributed satellites transmitting known signals, enabling precise channel estimation and phase correction via GPS localization.

The analysis demonstrates that this IoT-based telescope could significantly enhance antenna gain and survey speed compared to traditional telescopes like the Green Bank Telescope (GBT). Specifically, the IoT-based telescope enhances antenna gain by three orders of magnitude and increases survey speed by eight orders of magnitude. These improvements are attributed to the vast number of nodes and expansive field of view (FoV) offered by the IoT network.

While the proposed system offers significant advantages, it also presents several challenges. Calibration and interference mitigation in a noisy IoT environment are critical concerns. Data processing and management of the vast amount of data generated by the distributed nodes could also be complex. Further research is needed to address these challenges and optimize the performance of the IoT-based telescope. However, the potential benefits of this approach are substantial, paving the way for cost-effective, high-speed, and widely accessible astronomical observations.
