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

Low power consumption

CE compliant for EMI and RFI immunity

One year warranty
