Hi. When SBAS support is on, my receiver will sometimes pinpoint the position to within 1 meter, and sometimes down to 3-5 meters. I have the impression that the longer it is on, the worse the results. When SBAS is turned off, there is no problem, rather I have a constant accuracy around 1-2 meters, does SBAS have any additional configuration? does the L76 module make a correction only from one SBAS that is, in its opinion, the most accurate? can SBAS give worse results?
Is it possible for the SBAS module to detect only one channel / sat with the one it considers most accurate?
If it matters, I have option GPS+GLONASS in PMTK353 mode.
