Vector G2 & G2B

GPS Satellite Compasses


Affordable Vector G2 Provides Accurate Heading and Position Solutions

• Precise 2D heading and positioning data

• Heading accuracy of better than 0.5 degrees

• Rate of turn tracking rates up to 90ș/sec

• Pitch and roll accuracy of better than 1 degree

• Fully compatible with on-board Autopilot, Radar, AIS, PC, Sonar
