Vector VS131 uses Hemisphere GPS' Crescent ' ® Vector's patented technology brings a brand new user experience in undulations, pitch, roll, and even stronger positioning performance.
Vector VS131Key advantages of the receiver:
- Support L-band
- Professional directional accuracy<0.03 ° rms
- Differential positioning accuracy<30 cm rms
- Fluctuations<30 cm rms
- Pitch and roll<1 ° rms
- Concise menu operation
- Continuous accurate orientation for 3 minutes in case of unexpected GPS interruption
- COAST technology can maintain differential positioning accuracy for 40 minutes or even longer in the absence of differential signals
- Integrated gyroscope and tilt sensor can improve fast start-up time and provide heading update information in case of temporary loss of GPS signal
