[IGSMAIL-7897] 43rd COSPAR Scientific Assembly 2020 - Panel on Satellite Dynamics - abstract submission extended until 23rd February 2020

[Heike Peter]

Dear colleagues,

the abstract submission deadline for the 43rd COSPAR Scientific 
Assembly, 15-22 August 2020 in Sydney, Australia has been extended until 
23rd February 2020. So there is still the chance to contribute. We are 
looking forward to your contribution in particular for the event 
organized by the Panel on Satellite Dynamics and subcommision B2:

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.
