Abstract

The goal of the division is to address the scientific issues that were developed at the 2009 IAU General Assembly in Rio de Janeiro. These are:

Astronomical constants

—Gaussian gravitational constant, Astronomical Unit, GMSun, geodesic precession-nutation

Astronomical software

Solar System Ephemerides

—Pulsar research

—Comparison of dynamical reference frames

Future Optical Reference Frame

Future Radio Reference Frame

Exoplanets

—Detection

—Dynamics

Predictions of Earth orientation

Units of measurements for astronomical quantities in relativistic context

Astronomical units in the relativistic framework

Time-dependent ecliptic in the GCRS

Asteroid masses

Review of space missions

Detection of gravitational waves

VLBI on the Moon

Real time electronic access to UT1-UTC

In pursuit of these goals Division I members have made significant scientific and organizational progress, and are organizing a Joint Discussion on Space-Time Reference Systems for Future Research at the 2012 IAU General Assembly. The details of Division activities and references are provided in the individual Commission and Working Group reports in this volume. A comprehensive list of references related to the work of the Division is available at the IAU Division I website at http://maia.usno.navy.mil/iaudiv1/.
