Control with Gpredict (hamlib/rotctld)
The Satran has a simulated hamlib rotctl daemon or ”rotctld” that acts as a TCP server and can take
standard rotctl commands from compatible software, like the popular Gpredict program.
When power is connected and the rotator has initialized without errors the Satran is always listening
for rotctl commands, which makes setup very easy.
1) Power up the Satran and connect the computer with Gpredict either directly to the access point or
the wireless network that the Satran is connected to.
2) In Gpredict, click ”edit” and ”preferences” in the top bar
3) Press ”interfaces” in the left column and choose the tab ”rotators”. Press ”Add New”. Enter the
IP-address to the Satran and the other settings as pictured above. Press OK to close all.
4) In the main Gpredict window, now click on the small arrow icon in the top right corner to bring
up the menu containing ”Antenna Control”. Click on it.
