Hello everyone.
I did some research to understand the performance differences between the different chipsets using SBAS. Among my reading I came across the documentation for the Ublox NEO M8N where it is indicated at one point:
Each satellite services a specific region and its correction signal is only useful within that region.
Planning is crucial to determine the best possible configuration, especially in areas where signals
from different SBAS systems can be received:
Example 1: SBAS Receiver in North America
In the eastern parts of North America, make sure that EGNOS satellites do not take preference
over WAAS satellites. The satellite signals from the EGNOS system should be disallowed by using
the PRN Mask.
Example 2: SBAS Receiver in Europe
Some WAAS satellite signals can be received in the western parts of Europe, therefore it is
recommended that the satellites from all but the EGNOS system should be disallowed using the
PRN Mask.
Although u-blox receivers try to select the best available SBAS correction data, it is
recommended to configure them to disallow using unwanted SBAS satellites.
The EGNOS SBAS system does not provide the satellite ranging function.

I have also read in different places that integrity control could have a detrimental impact on the performance of a receiver in terms of precision (priority being given to integrity rather than precision), and that depending on its needs, it was more interesting to keep only the SBAS corrections and deactivate the integrity check.
My question is therefore: is it possible to configure these parameters on the LG290P? I saw in the documentation that the command . $PQTMCFGSAT allowed you to apply a mask to the system and the satellite identifier, but I don’t have the impression that this applies to SBAS satellites. And I didn’t find anything about the parameters of the SBAS data.
Does anyone have any information, advice, or opinion on this question?
Thanks
