Dear colleagues

The next COSPAR Scientific Assembly 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.

The Assembly is planned with in-person attendance dominating, but 
virtual participation will still be enabled.

In particular, we would like to draw the attention to a session, 
organized by the COSPAR Panel on Satellite Dynamics. The title of the 
session is "Satellite Dynamics - new Developments and Challenges for 
Earth and Solar System Sciences".

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-FO, Swarm, Jason series, 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 missions to 
explore the Solar System. Recent and future 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, OSIRIS-REx, Lucy), and harsh and 
unknown environmental conditions challenging our technical capabilities 
(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 for 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 as well as 
contributions on current progress on establishment, maintenance and 
improvement of reference systems in Geo- and planetary sciences.

Important dates:
11 February 2022: Abstract submission deadline
29 April 2022: end of early registration fees
