Develop sophisticated machine control and navigation solutions in a
world full of complex dynamic environments. The Vector™ H320™ is our
most advanced GNSS heading and positioning module available from
Hemisphere GNSS.
The Vector H320 utilizes dual antenna ports to create a series of additional
capabilities to Eclipse™ Vector technology including fast, high-accuracy
heading over short baselines, RTK positioning, on-board L-Band DGNSS/
HP/XP reception, RTK-enabled heave, low power consumption, and
precise timing.
Integrate the Vector H320 into your applications to experience exceptional
performance, flexibility and cost savings. This incredible GNSS module
uses advanced multipath mitigation techniques and offers full scalability
and expandability from L1/L2 GPS/GLONASS to L1/L2 GPS/GLONASS
RTK performance.
