[amsat-bb] Estonia's TTU100 X band satellite questions

[Graham Shirville]

Hi Ken,

The IARU website has this info 
http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=565 maybe 
you can contact the operator to find out the likely operating schedule.

Tracking the doppler will be fun and also keeping the dish within the 
required 1- 2 degree pointing  accuracy is also likely to be a 
challenge. However it appears that there may be a number of other 10GHz 
downlinks being planned for low earth orbit so all experience will be 
extremely valuable.
