| GNSS technology |
Leica patented SmartTrack+ technology:
- Very low noise GNSS carrier phase measurements with <0.5 mm precision
- High precision pulse aperture multipath correlator for pseudorange measurements
- Excellent low elevation tracking, fast aquisition time and jamming resistant
|
| GNSS Signals |
Flexible configuration, with up to 60 Satellites, 7 Signals per Satellite. maximum 120 Channels:
- GPS: L1, L2, L2C, L5
- GLONASS: L1, L2
- Galileo: E1, E5a, E5b, E5a+b (Alt-BOC) / Galileo (Test): GIOVE-A, GIOVE-B
- Compass*
- SBAS: WAAS, EGNOS, GAGAN, MSAS
*Test signals have been tracked in a test environment. As changes in the signal structure
may still occur, Leica Geosystems cannot guarantee full Compass compatibility. |
| GNSS measurements |
Fully independent code and phase measurements of all frequencies
- GPS: carrier phase full wave length, Code (C/A, P, C Code)
- GLONASS: carrier phase full wave length, Code (C/A, P narrow Code)
- Galileo: carrier phase full wave length, Code
