| Single frequency high sensitivity GNSS | GPS+BeiDou+Galileo（Asia） GPS+GLONASS+Galileo（Other areas） |
| Multi-frequency multi-system high-precision RTK GNSS | Frequency points used： GPS：L1/L2； GLONASS：L1/L2； BeiDou：B1/B2； Galileo：E1/E5 |
| First positioning time: <50 s | |
| Positioning accuracy: vertical 1.5 cm + 1 ppm (RMS); Horizontal 1 cm + 1 ppm (RMS) 1 ppm means that the error increases by 1 mm for every 1 km the aircraft moves |
