The Portsdown 4 ISS Tracker is designed to control an az/el rotator to track the ISS during a HamTV transmission. Initial testing has been on a G5500 rotator using the g5500pi controller (https://www.clearskyinstitute.com/ham/G5500/) connected to the rotator; however, other rotator controllers supported by HamLib rotctl may be compatible.
Portsdown Implementation
To access the rotator menu, go to M3, ISS HamTV RX Merger, ISS Tracker Set-up.
Before use, the Controller needs to be configured. Set either "Controller G5500pi" (the default) or "Controller HamLib".
If using the G5500pi controller, select "Set-up Controller" and enter the IP address and port of your controller in the format 192.168.2.140:8008. You may find it useful to allocate a fixed IP address in your network router for the controller.
If using the HamLib controller, select "Set-up Controller" and enter the HamLib device address. This is typically in the format /dev/ttyUSB2. Next enter the model number (the number in the first column of the table below), and the baud rate (typically 9600).
You should also enter the desired park position for your dish; the controller will move the dish to this position at the end of every pass. Select "Set Park Position" and enter the azimuth and elevation.
The configuration settings are stored for future use.
Now select "Track ISS". You should see the demanded position for the ISS displayed above the buttons, and the dish will move to track the position if it is more than 5 degrees above the horizon. Selecting "Track Moon", or "Track Sun" will also display the demanded position, and the dish will track if above 5 degrees.
