Orekit Event : 1st Session of OrekitTalk - DSST by Bryan Cazabonne

Hello the community,

I have the pleasure to announce that the 1st Session of the OrekitTalk, the webinar about Orekit, will be launched the 23rd May 2023 by CS GROUP.
You can register now to the event following this link :

The subject wil be presented by @bcazabonne on the evolutions of the semi-analytical DSST propagator in Orekit. As it is said, everyone could attend and the link is shareable.

I had some troubles on the configuration of the event so be careful that the event will start at 13h UTC+1:00 (Paris Time). Sorry also for non-french speakers as I was not able to put the “Microsoft Teams fields” in English.

If you have any problems to register or questions, feel free to share it on this thread !
I hope it will be a success and the first of a long serie of webinars :wink:

Update : You will find the link here to join the meeting.

Some statistics about the meeting:
We were 71 registered and 60 actually present during the meeting (we were targeting 50 people so better than expected).

The audience included a wide variety of players from industry, government, and academia.
Most of the people who attended were regular users of Orekit.
It proves that our community is alive and healthy, this is really great!

We will soon organize the 2nd OrekitTalk, so feel free to notify us if you are a candidate for the presentation.

See you soon!
