Análisis de la Estabilidad de la Estación LJEC de Monitoreo Continuo GNSS

Abstract

Abstract: This work addresses the stability analysis of the LJEC Continuous Monitoring GNSS station, located in Loja, Ecuador, during the period 2018-2022. Using time series, linear and non-linear trends were identified in the North, East, and Vertical (Up) coordinates, detecting minimal displacements that confirm the overall stability of the station. Although data gaps were recorded in some years due to maintenance, these did not significantly affect the quality of the results obtained. The study verified the GNSS data processing, demonstrating its accuracy and consistency, and highlighted the relevance of the LJEC station within the national GNSS network, which has approximately 70 stations. This system is fundamental for tectonic studies, land-use planning, and natural hazard monitoring in the country. As part of the conclusions, recommendations are proposed to improve station maintenance, incorporate advanced technologies for data analysis, and strengthen the national GNSS network. These actions will contribute to the development of geodetic and scientific knowledge in Ecuador.
