  1. Remote GPS Station at Langhovde, Dronning Maud Land, Antarctica Hiromichi TSUJI and Kenichi MATSUO* Geographical Survey Institute, Japan *JARE43 summer party member AGP'02 at LINZ, Wellington

  2. 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, Wellington

  3. 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. 39.58°, Lat. -69.01° ) • 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, Wellington

  4. 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, Wellington

  5. SYOG IGS Global Tracking Network http://igscb.jpl.nasa.gov/netwok/netindex.html AGP'02 at LINZ, Wellington

  6. GPS and VLBI antennasat Syowa station VLBI GPS (IGS ID: SYOG) AGP'02 at LINZ, Wellington

  7. Needs of Remote GPS station IGS station Continuous deformationobservation GPS controlpoint surveys Remote GPS station Crustal deformation surveys around bare rock areas AGP'02 at LINZ, Wellington

  8. 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.
