Anyone willing to point me in the right direction on a puzzle

Its a geocaching puzzle that involves multiple ciphers, and I'm stuck at a clue that seems to point to a SPnetwork.
This is output from a checkerboard cipher-
ggsortkaorossonontcvtnoodntvattprcrspsp

The next clue suggests squares or boxes, and the letters S,P

I'm solving for xx.xxx, yy,yyy- so I backed up a step, and divided the input to the checkerboard to get-GGRTORONCXONTUPRSP and
OSKAOSSONTBTODBATCRSP
there is a clue that deals with case sensitivity, so I've used a number base converter to input the letters as base64, but this SP network is over my head

the next clue seems to suggest keeping your lines straight, so I've been leaning towards the Rijndael s-box as wiki describes it involves an affine transformation that I think would satisfy the "keep your lines straight" clue

The puzzle was made to be solved, so I don't think he went too crazy with the encryption.
I've spent some time with pencil and paper using the binary output from the base converter and a basic s-box, but also reading as much as I can find and ran into the Rijndael hex table: pic related
my question to someone with better eyes for this stuff- Am I looking in the right direction with the Rijndael idea?
But really, any advice/ideas are appreciated

DES is so fucking easy, fuck off brainlet

Eye see

Thanks asshole-I'm trying to learn shit

Fun fun
Quads

Will someone explain why >>7963705 this polite gentleman is sure this is DES and not AES?
