Navigator G4 & G4B
GPS Satellite Compasses
Vector Sensor for
Precise Heading and Positioning
•
Affordable solution delivers 2D GPS heading accuracy better
than 0.1 degree
•
Differential positioning
accuracy of less than 1m (DGPS)
•
Integrated gyro and tilt sensor deliver fast start-up times and
provide heading updates during temporary loss of GPS
•
Fast heading and
positioning output rates up to 10 Hz
•
Differential options including SBAS (WAAS, EGNOS, etc.) and
optional beacon differential
•
Integral Display and User
interface installed separately near operator
•
G4B can utilize terrestrial Radio
Beacon Signals for DGPS corrections
•
Two antennas mounted separately
to meet desired accuracy
•
The status lights and menu system make the G4 Series easy to
monitor and configure
•
Advanced applications with user
friendly configuration menu
•
