Thanks
Hi Mohammed,

Thanks for the posts and the video!

Using TPAS it would be instructive to determine what your whole-sky
"raw" pointing performance is.

When syncing the time from the PC, it is important to be running an
NTP client and to check the status of that client to ensure
that it is in fact synced against one or more NTP servers.
Windows native Time Service can be out by several seconds. Microsoft
themselves recommend an NTP client for time-critical applications.

The current version of the Argo Navis/ServoCAT protocol specifies
a lock radius of 5 degrees for satellites. If you would like to do some
testing, we could experiment and extend that radius for you.

Best Regards
