Scheduling your first test observation

Assumptions:

If you've run into any problems with those steps, check out the Troubleshooting page or ask for help in the community forum, the Matrix room, or on IRC at #satnogs on Freenode.

SatNOGS Network:

  • Navigate your ground station page in the Stage Environment (user name -> "My Profile" -> click on the name of your ground station).
  • Select the "Upcoming passes" tab.
  • Look for a pass with a "schedule" button that isn't greyed out, and click it.
  • In the "New Observation" page that comes up, click the "Calculate" button, then click "Schedule".
  • You should now see a page for that observation; in the "Waterfall" tab, you should see "Waiting for waterfall".

Ground Station

Now SSH to your ground station computer and run these steps:

  • Follow the satnogs-client logs. Depending on your setup, this might be done with journalctl -f -u satnogs-client.service, or tail -F /var/log/supervisor/satnogs.log
  • Before the observation is scheduled to start, you should see your client wake up once per minute to check for new jobs:

  • After the observation is over, you should see the client submit the data to the SatNOGS network

In the SatNOGS Stage Environment, refresh the Observation page. You should now see a waterfall plot for your data.

If that all worked -- congratulations! You've just successfully completed your first SatNOGS observation.

If it didn't work, don't feel bad -- it can take a few attempts before you get it right. Have a look at the Troubleshooting page for tips, and don't forget to contact the community if you need help.
