Introducing the Luna Mini Monitor!

[Mag_Neato]

Maybe:
Sierra Sat Center (Standard)
Sierra Sat Center N (NrT)
Sierra Sat Center R (RAAL)?

My suggestion:

Sierra-1 C-SAT
Sierra-1N C-SAT
Sierra-2 C-SAT

As was my line of reasoning with the non-center Sats, match the numeric designation with the full size Sierra line.

So.....
Sierra-1 SAT
Sierra-1N SAT
Sierra-2 SAT
