Features
• Patented Z-tracking to track encrypted GPS P(Y) signal
• Patented Strobe™ Correlator for reduced GNSS multi-
path
• Patented Z-Blade technology for optimal GNSS
performance:
– Highest quality of raw data (availability/reliability) to
meet reference station applications
– Full utilization of signals from all seven GNSS systems
(GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, and
SBAS)
– Enhanced GNSS-centric algorithm: fully-independent
GNSS signal tracking and optimal data processing,
including GPS-only, GLONASS-only or BeiDou-only
solution (autonomous to full RTK)
