Is SBAS enabled on the GNSS receiver by default??  Is such capability available? I would imagine it is.

Is so, if all constellations are enabled, how does one choose specific SBAS prns ? (EGNOS vs WAAS)

On concurrent receivers, best practice is to apriori choose SBAS PRN's over your area.

Thank you!

Hello,

Regarding the supported satellite for GNSS on our device.

We are currently supporting: GPS, BeiDou, QZSS, GLONASS, and Galileo

Hope it helps

Thank you. Yes, I knew you supported this constellation. The question was if a user could select a particular constellation for SBAS. If you had a uBLOX receiver inside the RUT955 (which you don't), you could select:

1) If SBAS was enabled

2) Which PRNS to use.

I know you are using some other chipset which embeds various functions (inlcuding GNSS reception).

Please clarify ...

Thanks

Hello,

I have received reply from our RnD team.

Yes, SBAS enabled by default in all firmware for chipset 9x07 (t.y. EC25)."SBAS systems typically use only one GNSS constellation - typically is GPS. you cannot change the GNSS subsystem operating mode, so, you can called this AUTO mode. Also you cannot choose a regional constellation."
