Hi! This is my second review of this I-D; I compared -04 to -05.  I had two points:

1. Thanks for a greatly improved security considerations section. While it is still essentially empty, now readers will know why! ;)

Changing my review to "Ready" based on the changes to the security considerations. 

2. I am going to infer from the changes made in s5.3 (dropping the intro sentence and adding the sentence about the ground station) means that mobile satellites are not a non-deterministic scenario. But, it would be nice to confirm this.

Cheers,
