Abstract: |
The objective of solar system astrometry is the regular and
accurate ground-based observation of positions and motions for all objects
in the solar system - including spacecraft. We describe the status
of the four principal observational techniques, especially the remarkable
gains in accuracy of the last 10-20 years. Even though, this activity is
indispensable to the support of several important applications, such as
spacecraft navigation and collision hazard assessment, it will fall short of
its main objective unless access to specialized and large telescopes, and
to radar and VLBI facilities is increased to full growing requirements.
New facilities and continued support of astrometric observations are recommended. |
