Event Name: L3: **Updated in STK 12.8** Constrain line of sight with Chains & Constellations
Location: Online
Date(s): Feb-13
Time: 12:00 p.m. - 1:00 p.m. (ET)
Price: Free

Engineers and technicians require a simple, quick way to analyze if/when an object has line of sight to a group of objects, not just a single object. This class will walk you through setting up an STK scenario to determine how many satellites, in a constellation of satellites, you can track both individually and in groups of four or more. Using Chain and Constellation objects, you will analyze how many satellites a ground sensor can see during a 24 hour period. Then you will add a constraint that the sensor must see at least four satellites simultaneously and see how that affects access.

Upon completion of this class, you will be able to:

  • Constrain Constellation objects
  • Create a chain object
  • Generate and understand a Complete Chain Access Report

Follow along on your computer as an instructor walks you through this focused STK lesson. AGI engineers will be available during the session to answer your questions, live.


This lesson has been updated to highlight the changes to the chains object in STK 12.8. If you want to follow along with the instructor, it will require you to use STK 12.8. If you are unable to upgrade STK to 12.8 before this class, you can use STK Cloud, a web-based version of STK. There is nothing to download in advance with STK Cloud. It does not require a license or software install. If you would like to use STK Cloud, please select that option when registering and use the link provided in your confirmation email the day of the class to access STK Cloud. To use STK Cloud, you will need the following:

  • An account
  • HTML5-capable browser (IE is not recommended)
  • Fast, stable Internet connection that allows web-socket connections - test your connection here
