Configuration update required for rotator stations with satnogs-client 1.1

Since 2020-02-28, satnogs-client 1.1 is distributed to stable ground stations (satnogs-client-ansible@5c9661a).

In satnogs-client version 1.1 the possibility to access the rotator without running a rotctld instance was added (see commit satnogs-client@74d8eec). The configuration variables SATNOGS_ROT_IP and SATNOGS_ROT_PORT in their original meaning of an IP address & port were removed, and the new variables SATNOGS_ROT_MODEL, SATNOGS_ROT_BAUD and SATNOGS_ROT_PORT were added. Thus changing your configuration is required.

SatNOGS as exclusive rotator user

If you are using your rotator exclusively with SatNOGS, it’s now possible to let the SatNOGS Client talk directly to the rotator without running a rotctld service. For this, you have to set the following variables:

Variable Description
SATNOGS_ROT_MODEL The Hamlib rotator macro name for your rotator model. Choose your model from this list of rotator models in Hamlib
SATNOGS_ROT_BAUD The Baud rate for the rotator serial port (e.g. 19200)
SATNOGS_ROT_PORT The Serial port your rotator is attached to (e.g. /dev/ttyUSB0)
~~HAMLIB_UTILS_ROT_ENABLED False (default, i.e. not required anymore) ~~

You can also find these new configuration options with short explanatory text on the SatNOGS Client Setup wiki page.

“co-hosted” SatNOGS

If you want to continue to let rotctld manage your rotator (e.g. because other software is using it sometimes, or the rotator is controlled by a different machine in your network), you can continue to let satnogs-client access the rotator through the TCP socket. Use the following variables:

Variable Description
SATNOGS_ROT_MODEL ROT_MODEL_NETROTCTL
SATNOGS_ROT_BAUD 0 or leave it with default value
SATNOGS_ROT_PORT IP:PORT, e.g. localhost:4540
~~HAMLIB_UTILS_ROT_ENABLED False (default, i.e. not required anymore) ~~

In case of questions or problems, please open a thread here in the forum or via chat on the Matrix room #satnogs:matrix.org.

Thanks, @kerel!

If you like to have a dedicated controller hardware (e.g. a separate RasPi where your rotator control box is connected to) you need to run a rotctld service on this device. You may want to start it something like this:

rotctld -m 602 -r /dev/LVBTracker -s 9600 0.0.0.0:4355

You can add -vvvvv to get full verbose debug output on a commandline. Once you‘re satisfied with your configuration add rotctld as a service started on system boot.
