PICO
The precise positioning at centimeter level with GPS has been available for decades, which is lately strengthened by the emerging Global Navigation Satellite Systems (GNSS), such as the European Galileo, Chinese BeiDou, and Russian GLONASS, making positioning cost-effective and compact. OEM boards of various qualities and single-board microcontrollers allow construction of low-cost/mass-market/consumer-grade GNSS receivers that are used for applications requiring precise positioning, sensor synchronisation, GNSS reflectometry, phase time delay and signal attenuation. These applications are spread over fields such as geodesy, hydrology, (hydro-)meteorology, volcanology, natural hazards, cryospheric and biospheric sciences and (urban) navigation. Moreover, they are valuable for deriving and monitoring geophysical phenomena such as sea-level rise, crustal or surface deformation. We solicit abstracts on instrumentation and innovative applications in different fields of research, as well as algorithms, and sensor calibration and integration. We welcome any other contributions that highlight the challenges of using low-cost GNSS receivers and antennas.
