A not too difficult puzzle, so Don’t Panic.
Without going to the posted coordinates, hitch onto the theme, ignore the Red Herring and solve the sums below to get the missing numbers for the final coordinates.
Final is at S41 30.BCD E173 49.JKN
Where:
B = SLATFATF - LTUAE
C = LTUAE + THGTTG
D = RH
J = TRATEOTU - RH
K = MH + SLATFATF
N = LTUAE + TRATEOTU
