Satellite passes - Email and SMS/texting alerting system

Now you could be alerted on your mobile device¹⁾ and/or email just before your favorite satellite comes over the horizon!

This is what you have to do:

Set your email address and your mobile phone number¹⁾ on your profile. Make sure the information is valid.

Create your default observing location. If you already have one created, it would be automatically selected. If you have more than one, make sure you select a location where you are physically located so the alert would make sense.

You are now ready to create your first notification. Select a LEO (Low Earth Orbit) satellite so that you could see the "5-day predictions" link. A great choice could be the International Space Station (ISS). Click the "5-day predictions" link. Take this shortcut for ISS.

By default you will see the visible passes of the satellite over your area for the next few days. You could display all satellite passes once you click on "See all passes" button. The "all passes" list could be useful for those performing radio communications via LEO satellites (e.g. amateur radio enthusiasts). Click on "Details" button.

You should now see among other things the "Add this pass on your notification list". Click it.

The pass is now added on your notification list so you just have to select when to be alerted and how.

When? There are 3 choices: 10, 20 or 30 minutes before pass beginning. Choices are selectable via a dropdown list.

How? By email (the message is sent at the address on your profile) and/or by SMS (Short Message Service) known also as "texting" (sent at the mobile phone number on your profile)¹⁾.

Once you click on "Set alert" you are done. Just wait for the alert to come. You could have more than one notification active at a given time. All active notifications are listed here. Expired notifications are removed from the list.

The alert sent by email contains all details about the pass as seen on the web site.

The alert sent by SMS/texting contains only a few details about the pass since a limited number of characters are allowed by this service.
