LVS is an extension of MER-DIMES
MER-DIMES (2004) was the first use of descent images for navigation during EDL.

TRN
TRN automatically matches features in a descent image to landmarks in a map to obtain a position fix.

DIMES tracked features between descent images to estimate velocity.
TRN is an extension of MER-DIMES to estimate position for accurate landing.
