Projects of Division I

At the 2009 IAU General Assembly specific projects were identified for possible future investigation by the member commissions and working groups of IAU Division I. These are:

• Astronomical constants
  • Guassian gravitational constant, Astronomical Unit, GM_sun, 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
