Geodesy and Geographic Programs under JARE Planned & Implemented by
Geographical Survey Institute (GSI) for Geodesy, Photogrammetry, and Cartography
Hydrographic and Oceanographic Information Department (former JHD) for Charting and Tide gauge observation, and
National Institute of Polar Research (NIPR) for Geosciences and Place names
Programs include GPS, VLBI, and Remote sensing Global Mapping (1:1M digital data)

RGS at Langhovde GSI installed a remote GPS station at
Langhovde in January 2000. A built-in battery and wind / solar
power plant enable continuous GPS observation at a remote site, 27 km south of Syowa base.
Currently, data with 120 seconds interval are stored in PC and retrieved by GSI staff once per year.
