Heading Sensor Antenna

Brochures And Manuals

Feature

  • Hemisphere GNSS’ exclusive COAST™ technology
  • Crescent and Crescent VectorII technology
  • Tilt sensor on each axis (X and Y axes)
  • Dual integrated GPS antennas
  • V104s’s GPS antennas are separated by 13.5 cm between their phase centers, resulting in better than 2° rms heading performance.
