Does STA8135G support Galileo E6 HAS raw data?

Donald11 · ‎2026-01-19

Since STA8135G is a triple-frequency GNSS chip, its hardware should have the capability to decode the E6 HAS message. However, I can't find related message from its RTCM output.

I have searched the web and was informed that it can be supported by upgrading to certain firmware, named Measurement Engine (ME) Firmware.

Can anyone help to tell me where I can find the suitable firmware, and whether I can do the upgrading and make my chip a more precise one?

Hi,

We can receive Galileo E6 signals but we do not have the ability to decode E6 HAS signals for PPP. If you are using an external 3rd party decoder we can provide you measurement data.

In addition, STA8135 being a chipset, the information is provided only under NDA.

Do you work with ST sales or local distribution in your region? May I ask what region are you located?
