International workshop on
GEodetic Measurements
by the collocation of Space Techniques ON Earth
(GEMSTONE)

25-28 January, 1999 Koganei, Japan
hosted by
Communications Research Laboratory

Communications Research Laboratory hosted an international workshop named GEMSTONE (International workshop on GEodetic Measurements by the collocation of Space Techniques ON Earth) which is sponsored by the Science and Technology Agency in Japan in January of 1999.

Importance of collocation between the space techniques has been stressed. Although we had limited number of collocated stations in the past, the situation is changing. We can study systematic errors which may be invisible by a single technique, through the collocation. From a collocation, we may understand the behavior of the atmosphere and other physical effects. These study will lead us the reference frame improvement. On the other hand, we have to solve the technical problems such as ground surveying. This workshop will focus a topic of collocation in the aspects of the technical points and its contribution to the geodesy and astrometry.
