Scheduling your first test observation

Prerequisites

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

SatNOGS Network Screen capture

  • Navigate your ground station page in the Network 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. Ensure it is a good (high) pass of an operational satellite (check the color bar on the satellite)
  • 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".
  • You can also schedule multiple observations at once for a single satellite via the "Observation new page".

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.

Rating observations

Once your observation results are posted back in the Network by your satnogs-client, you should go to Network to rate your observations. Any orange marked observations need vetting by users.

Idea.png
The main purpose of validating observations is to know if the satellite/transmitter is alive, if it transmits in the listed frequency/ies, and if the TLEs we have are accurate.
Idea.png
The functionality may change in the future, but for now even a faint sign on the waterfall is enough to make it valid.
Orange need your rating!

Categories of observations:

  • Good
    • You should mark observations as "Good" when it is clear from the waterfall and/or audio recording that a satellite is present. Keyboard Shortcut 'g'
  • Bad
    • You should mark observations as "Bad" when by examining the waterfall and/or audio it is obvious that there was no satellite detected in this observation. Keyboard Shortcut 'b'
  • Failed
    • You should mark observations as "Failed" when the station failed entirely: the waterfall and/or audio is empty or not present, or there's too much noise. Keyboard Shortcut 'f'

Below is a collection of waterfalls with possible results of observations:

You can see more examples of observations and ratings and a Taxonomy_of_Observations.

Click the "Discuss" button to post in our web forum. (Note: this will only appear in the SatNOGS network.)

Discuss

If you're still unsure about an observation, click the "Discuss" button, near the top right of the observation's page; that will post a link to it on the Observations forum, where you can ask for feedback.
