Do you have any documentation with example on Satellite library?
What are the functions, methods available ? how to used them in DTM ?
Link to DTM Docs under Adobe Marketing Cloud Help
Also, here's a starting point in Video... DTM - Overview and Set Up Basics - YouTube
Here's the whole playlist: Dynamic Tag Manager (DTM) - YouTube
This is the object reference: Dynamic Tag Management Object Reference
BTW, If you are just starting out and you can make the choice between DTM and Launch, you should choose Launch since DTM will be sunsetted over the next few years.
Thanks for your reply.
Hope this helps.
The Launch docs have more details on the methods you can use.
