geosf.py sračunava dužinu, broj letvica i broj potrebnih konektora za izgradnju Geodetske kupole

Detaljno objašnjenje Šta je Geodetska Kupola i kako se izračunava?

geosf.py koristi tabelu strut faktora za određeni tip kupole i frekvenciju (postoje gotove vrednosti za svaku kombinaciju):

Frekvencija

Tip kupole

Oznake letvica

Dijagram montaže
