AGP'02 at LINZ, Wellington2 Contents Background Geodesy programs under JARE IGS station at Syowa from 1995 Needs of Remote GPS station Installation at Langhovde in Jan 2000 Performance by Feb 2002
AGP'02 at LINZ, Wellington3 JARE program Japanese Antarctic Research Expedition started in 1956 in response to IGY Organized by National Institute of Polar Research Funded by Ministry of Education, Science, Sports and Culture Syowa Station established in 1957 On the East Ongul Island, the Eastern Dronning Maud Land (Lon °, Lat ° ) Observation parties stationed at Syowa Summer party: 5 months from Nov with 20 staff Wintering party: 17 months from Nov with 40 staff
AGP'02 at LINZ, Wellington4 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)
AGP'02 at LINZ, Wellington5 IGS Global Tracking Network SYOG
AGP'02 at LINZ, Wellington6 GPS and VLBI antennas at Syowa station GPS (IGS ID: SYOG) VLBI
AGP'02 at LINZ, Wellington7 IGS station Remote GPS station Crustal deformation surveys around bare rock areas GPS control point surveys Continuous deformation observation Needs of Remote GPS station
AGP'02 at LINZ, Wellington8 RGS at Langhovde GSI installed a remote GPS station at Langhovde in January 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.
