The magnetic poles, or dip poles, are the points where the geomagnetic field is vertical. Their experimental determination from ground surveys is difficult, due to the harsh environmental conditions of polar areas and their short-term displacement due to the magnetosphere-solar wind interaction. We statistically estimate the position of the South magnetic pole using data from SWARM satellites along their almost polar orbits during 2014--2018. We investigate the magnetic-pole position and its long term variation and dynamics under different geomagnetic and interplanetary medium conditions, also comparing our results with those provided from analytic models.
