COSPAR 2021 HYBRID, 43rd Scientific Assembly
28 January - 4 February 2021, Sydney, Australia

Dear colleagues

Apologies for the very late notice!

The 43rd COSPAR Scientific Assembly (28 January - 4 February 2021) is 
going Hybrid and the call for abstracts have reopened until 5 October 
2020. In addition to the already existing program new abstracts can be 
submitted.
More information about how the Hybrid Assembly will work may be found at 
http://www.cospar2020.org/abstracts.php

In particular, we would like to draw the attention to a session, 
organized by the COSPAR Panel on Satellite Dynamics together with 
sub-Commission B2 “International Coordination of Space Techniques for 
Geodesy” (identical to IAG Commission 1 on Reference Frames). 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-3, 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 Geosciences.

Important dates:
5 October 2020: Abstract submission deadline
30 November 2020: Deadline to register at "presenter early bird rate" 
(if pre-recorded talk has already been uploaded)
31 December 2020: Deadline to register at standard early bird rate
