The geo-locations of the stations are depicted in the regional map in Indian longitudes. It may be noted that the GPS station (circle) and the EEJ derivation stations (triangles) are nearly at the same longitude sector. The dashed curves represent the ±15° latitudes, i.e., the approximate positions of the crest regions of the equatorial ionization anomaly.
