_BIAS |
For receivers with Glonass HW Bias solution, which include a table of Glonass HW Bias internally and apply it accordingly. This improves micro fix rates, reducing short, invisible mis-fixes. |
SC Retrofit, SC Rover, Septentrio, U-blox, MOVA, and other Asian brand receivers. |
|
_RAW |
For receivers without Glonass HW Bias solution. These receivers do not have a table to solve Glonass HW Bias. |
All Komatsu ICT equipment, Topcon, Trimble, and Leica rovers. |
