Dear colleagues

The next COSPAR meeting will attract about 3000 scientists and engineers 
from the world over. More than 100 symposia will cover all areas of 
space science: Space studies of the Earth’s surface, meteorology and 
climate, Space studies of the Earth-Moon, Planets and small bodies of 
the solar system, Space studies of the upper atmospheres of the Earth 
and Planets including reference atmosphere, Space plasmas in the Solar 
system, including planetary magnetospheres, research in astrophysics 
from space, life sciences as related to space, material sciences in 
space, fundamental physics in space, and several Panel meetings.

Interdisciplinary lectures will also be given by key scientists and 
several associated events are planned, such as a meeting organized by 
Elsevier for young scientists to help them publish or review scientific 
articles.

In particular, we would like to draw the attention of geodesists to a 
2-days meeting, organized by the COSPAR Panel on Satellite Dynamics, in 
conjunction with IAG Commission 1.

The aim of the Panel on Satellite Dynamics is to support activities 
related to the detailed description of the motion of artificial 
celestial bodies. This goal should be achieved by improving the current 
theories of motion and by evaluating their determining forces in a more 
sophisticated way. Detailed theoretical understanding of the dynamics of 
satellites should coincide with the results of precise tracking in order 
to obtain the most precise knowledge possible of the orbit and the 
corresponding orbital positions.

The scope of the Panel on Satellite Dynamics entails the positioning of 
a wide range of objects in space, including Earth orbiting satellites 
for Earth observation such as GRACE, Swarm and the Copernicus Sentinels, 
and navigation satellite systems such as GPS, GLONASS, Galileo, Beidou, 
QZSS or tracking systems such as SLR and DORIS. In addition, positioning 
plays an important role in the success of the continuously growing 
number of today's and tomorrow’s planetary and solar system missions. 
Recent and future solar system missions have to deal with complex 
trajectories and innovative propulsion and breaking techniques to visit 
multiple bodies (e.g., Cassini, Dawn, JUICE), small unconventional 
bodies (e.g., Rosetta, AIM), and harsh and unknown environmental 
conditions at the edge of exploration (e.g., Messenger, Venus Express, 
BepiColombo, JUNO). Both advances in the modeling of spacecraft dynamics 
and the theoretical understanding of space observables (e.g., range, 
Doppler, VLBI, optical) are required to allow a more efficient 
exploration and a deeper understanding of our Solar System.

Limiting errors in Precise Orbit Determination (solar radiation 
pressure, time variable gravity fields, phase center corrections, 
attitude variations, etc...) are of critical interest for many 
stakeholders. Moreover, formations of satellites are being realized and 
proposed for Earth observation and fundamental sciences, that impose 
very severe constraints on (relative) positioning and orbit and attitude 
control solutions (e.g. micro-propulsion). Mini-satellites and cubesats 
also represent a new frontier for both Earth and planetary exploration, 
posing new challenges as well as new opportunities.

Satellite orbit determination requires the availability of tracking 
systems, well established reference frames and accurate station 
coordinate solutions, detailed force and satellite models, and 
high-precision time and frequency standards.
Contributions covering all recent developments and plans in ground, 
satellite or probe positioning and navigation are solicited.

Important dates:
9 February 2018: Abstract submission deadline
27 April 2018: end of early registration fees
