Looking at the Qualcomm (or qcom) chipsets in GPSTest Database and also from my own testing of older chipsets (2017), that qualcomm chips do not support (or at least do not communicate) the carrier phase data.
Recently Trimble has teamed up with Qualcomm to provide better location services. They performed the test on Xiaomi 12T Pro powered by the Snapdragon 8+ Gen 1.
Does anyone have this device/chipset or newer that could help tell me if the device communicates carrier phase information?
Thank you
