Vector V123 Smart Antenna

The Vector V123 is Hemisphere GNSS' all-in-one single-frequency, multi-GNSS smart antenna which provides Atlas decimeter-level position and precise heading. This rugged design is sealed for the harshest environments and is a great solution for professional marine and other challenging applications.

The all-in-one V123 combines simple installation with consistent and precise heading accuracy and decimeter positioning.

Note: This devices requires a Power and Serial cable such as part 880-1043-000 or 880-1043-000. Sold separately.

  • Simple all-in-one single-frequency, multi-GNSS heading solution
  • Single-frequency GPS/GLONASS/ BeiDou/Galileo/QZSS
  • Atlas® L-band capable
  • Integrated gyroscope provides smooth, fast heading reacquisition
  • Reliable < 1° per minute heading for periods up to 3 minutes when loss of GNSS has occurred
  • Fully rugged solution for the harshest environments
