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.
