Here are some common questions about performing kinematic and redused dynamic orbit determination for LEO satellites using Ginan:

[PingaNNU]

Is spire_pod.yaml a configuration file for kinematic and redused dynamic orbit determination of LEO satellites?

How can I download the sample data and products used in this file? I am unable to download them using the current script.

Hi PingaNNU,

Thank you for your question. The spire_pod.yaml file is indeed a configuration file used for kinematic and reduced dynamic orbit determination of LEO satellites.

Regarding the sample data and products, unfortunately, Spire LEO data are not freely available for public download. These data are only accessible if you purchase them or if you have access as a NASA investigator to their archive. Therefore, the current script will not be able to download the data without the necessary permissions.

However, we will be providing an example on how to use Ginan to determine the position of LEO satellites using GRACE data, which are easier to access, in the coming weeks.

If you have any further questions, please feel free to ask.

Best regards,
Sebastien

Dear senior,

Thank you so much for your kind response! I'm writing to humbly inquire whether there are any examples of precise orbit determination using the GRACE satellite that have been made available. I would be extremely grateful if you could kindly let me know where I can find such examples.

I'm currently very eager to delve into the LEO satellite orbit determination function of Ginan. It would be really helpful if there were a detailed example covering LEO satellite kinematics and reduced-dynamics POD for me to study. I would greatly appreciate your guidance and advice in this regard.

Thank you again for your time and consideration.
