Observations from Global Navigation Satellite Systems (GNSS) reveal that plate motions exhibit a full spectral behavior, encompassing transient patterns ranging from minutes to decades and from kilometers to continental distances. TectoVision, an ERC project hosted at Ruhr University Bochum and GFZ (PI: Prof. J. Bedford, RUB), is pioneering a comprehensive pipeline that encompasses both upstream and downstream components in the analysis of raw GNSS data for modeling transient tectonic deformation. This project aims to seamlessly integrate upstream processes, including GNSS network configuration, processing strategies, and the generation of GNSS time series. Simultaneously, TectoVision will extend its reach downstream, focusing on the intricate aspects of time series analysis and the subsequent geophysical interpretation. In essence, TectoVision's distinctive approach involves not only harnessing the raw GNSS data but also orchestrating a holistic flow that encapsulates the entire spectrum, from network configuration and data processing to the nuanced realms of time series analytics and geophysical interpretation. In an additional effort to drive innovation, TectoVision has incorporated cutting-edge, low-cost GNSS equipment into its GNSS network, with the Minimum Cost GNSS System (MCGS) and the tinyBlack  standing out as two prominent technologies.

GFZ’s activities in TectoVision are along the GNSS infrastructure (provision of GNSS hardware, GNSS data operations, and processing) and the scientific GNSS investigations, like optimizing the analysis strategy and assessing the impact of sub-daily coordinate estimation.
