♣ Data Archives and Distributes
JAXA archives and distributes GNSS data sets of sufficient accuracy to meet the objectives of a wide range of scientific and engineering applications and studies.
However, JAXA does not guarantee any availability and precision of the data.
JAXA also assumes no responsibility for any damages occurring when a user uses a data.
JAXA may interrupt, stop and terminate product distribution.
The user shall indicate proper credit when the user publishes analyze results from a product.
