Steve,
When you activate the aircraft for the first time, you activate the 1 year free of Terra.
You will be sent an email with instructions on activation.
Some notes:
It is not a full version of Terra. You can only use images from a Matrice 4 series aircraft.
I had plans to process data sets I have from other drones. This will not work with this limited version of Terra.
From the email:
