%X This work analyzes the monitoring of the covered and regenerated Horcones Inferior Glacier (HIG) since the implementation of a semi-permanent GNSS station (HISS) on its surface during the summer seasons of 2009 and 2010. The glacier is located at 32∼ 41's and 69∼ 57'w, at the foot of the south wall of Mt. Aconcagua, Aconcagua Provincial Park, Mendoza, Argentina. The average velocities obtained from the HISS station were of 1.3 cm/d and 3.5 cm/d during the 2009 and 2010 seasons respectively. The data procured using satellite images during the last surges (1984 and 2003) gave average velocities for the HIG front of 8.7 m/d for the first event and 11.5 m/d for the second one. These results allowed getting accurate and reliable movement tendency at the terminal part of the HIG during the 1984-2010 period. El presente trabajo realiza el monitoreo del glaciar Horcones Inferior, cubierto y regenerado a partir de la implementaci車n de una estaci車n GNSS semi-permanente (HISS), instalada sobre su superficie durante las temporadas de verano de 2009 y 2010 respectivamente. El glaciar se encuentra ubicado a los 32∼ 41's y 69∼ 57'w, al pie de la pared sur del C∼ Aconcagua, en el Parque Provincial Aconcagua, Mendoza, Argentina. La estaci車n HISS registr車 valores de velocidades medias de 1.3 cm/d y 3.5 cm/d durante las temporadas de 2009 y 2010. Se utilizaron im芍genes satelitales para el seguimiento del frente del glaciar durante los 迆ltimos surges (1984 y 2003), cuyas velocidades medias fueron de 8.7 m/d para el primero y de 11.5 m/d para el segundo evento. Estos resultados permitieron obtener de manera precisa y confiable la tendencia de movimiento de la parte terminal del GHI durante el periodo 1984-2010.
