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
