Technical Data
1 The hardware is prepared for new signals and is designed for BeiDou Phase
2, Phase 3, B1, B2, B3 and Galileo commercial service compatibility. The
firmware will be enhanced to support new signals as soon as the officially
published signal interface control documentation (ICD) becomes available
and the systems operational constellation allows for commercial practical
use. Generally, the tracking capability for a specific satellite system is based
on publicly available information. For cases where public information is sub-
ject to change or not yet available, Leica Geosystems cannot guarantee
that these receivers will be fully compatible with a future generation of sat-
ellites or signals.
GPS/QZSS L1C, GLONASS L5 CDMA, Galileo E6, QZSS L6 and SBAS L5 will be

provided through future firmware upgrade.

Condition GR30/GM30/GR50
L1, AS off or on Reconstructed carrier phase via C/A-code.
L2, AS off Reconstructed carrier phase via P2-code.
L2, AS on Switches automatically to patented P-code aided techni-
que providing full L2 reconstructed carrier phase.
Condition GR30/GM30/GR50
L1, AS off Code measurements: C/A-code.
L1, AS on
L2, AS off Code measurements: P2-code and/or L2C code.
L2, AS on Code measurements: Patented P-code aided code and/or
L2C code.
Code smoothing using carrier phase measurements is optional.
The SmartTrack+ Advanced Interference Mitigation option offers resilient signal
tracking ensuring reliable GNSS multi-frequency operation even in challenging
environments.
The radio frequency power spectrum levels can be measured and output at
configurable density and update rate for all GNSS bands.
Leica Interference Toolbox desktop software allows to easily monitor, quantify
and enable mitigation options on the receiver to remove interference sources
impacting the receiver performance.
