The objective of this research is to create and study a long-range, low power wireless IoT network using bleeding edge technology: the new Galileo high accuracy service and LoRa communication [https://www.semtech.com/lora]. Due to the success of the first project, we refer to this system as CommBuoy (and apologise for the ambiguity). LoRa can be used to transmit sensor data where no electrical grid or other communication networks are available, e.g. highlands, ocean, or after a disaster. For the ocean, ranges of up to 83.6 km have been reported [Radeta et al., 2020; Parri et al., 2019]. Using the low-power LoRa wireless network together with a low-power Internet of Things (IoT) device, the system can be powered by battery (with optional power supply by a solar panel) and remain on the buoy after installation so that it can be used for monitoring, e.g., report any drift of the buoy or data from any other sensors attached. The target battery-operated lifetime is two years. The project aims at exploring the new Galileo HAS service and its performance in Iceland. This is worthwhile since it means great simplification of the unit used for buoy installation as well as the communications needed. Furthemore, the HAS service will be valuable in a range of other applications important for Vegagerðin, yielding increased value of this study. The research prototype system (utilizing differential correction data for GPS) will be taken to the next stage. This means switching to the Galileo HAS, developing energy-efficient buoy unit, and integrating the new components to the core system. The prototype system is further evaluated by means of experiments and field trial(s). References
