Validation of a low cost gnss receiver for ionospheric total electron content monitoring at the periphery of the south atlantic magnetic anomaly: a two week commissioning dataset from mthatha, south africa

Key Points

This research aims to validate a low-cost GNSS receiver for monitoring total electron content in the ionosphere.
Commissioning of a dual-frequency GNSS receiver station at Walter Sisulu University.
Continuous observations conducted over two weeks in October.
Location strategically chosen at the eastern periphery of the South Atlantic Magnetic Anomaly.
Successfully filled a 340 km observational gap in the ionospheric monitoring network.
Data effectively captured total electron content variations in the region.

Abstract

This paper presents commissioning results from MTHA-SA, a low cost dual frequency Global Navigation Satellite System (GNSS) receiver station installed at Walter Sisulu University in Mthatha, South Africa (31.59°S, 28.78°E; L ≈ 1.9). The station occupies a scientifically strategic position at the eastern periphery of the South Atlantic Magnetic Anomaly (SAMA), filling a 340 km observational gap in the regional ionospheric monitoring network. Two weeks of continuous observations during October 1–1
