The data from the GNSS receiver will be used for precise positioning and water vapour studies. South Africa has operated a weather station on Gough Island since 1956. This weather station is important as our weather mostly comes from the south-west and the weather station at Gough Island gathers important initial information on advancing weather fronts.
The island has a volcanic origin and reaches a height of about 900 metres above sea level and has a surface area of 91 square kilometres. It is administered from Tristan da Cunha, which is a dependency of the British overseas territory of Saint Helena. It is planned to install a tide gauge and seismometer on Gough Island during 2013, in collaboration with Germany.
The new SANAP research ship (Agulhas II) provided safe transport to Gough Island. Logistics were provided by the Department of Environmental Affairs (DEA). HartRAO also operates a GNSS station on Marion Island in the Southern Indian Ocean and at the South African Antarctic base SANAE IV, as part of the SANAP Space Geodesy Programme.
