What Ionospheric Correction will SETIONOTYPE AUTO use?

SETIONOTYPE AUTO will use the best possible ionospheric correction:

  • If the receiver is an L1+L2 model, SETIONOTYPE AUTO it will always use the L1L2 option
  • If the receiver is L1 only, SETIONOTYPE AUTO will use the KLOBUCHAR broadcast model
  • If the receiver is L1 only and SBAS is enabled, SETIONOTYPE AUTO will initially use KLOBUCHAR and then switch to GRID after a few minutes.
