Hemisphere V103 GPS Heading Compass (940-3116-0)

Hemisphere Part Number: 940-3116-0

Hemisphere V103 GPS Heading Compass


  • Integrated gyro and tilt sensors deliver fast start-up times and provide heading updates during temporary loss of GPS
  • Smart antenna design ensures simple installation into finished product
  • Affordable solution delivers 2D GPS heading accuracy better than 0.3 degree rms
The Hemisphere V103 Professional Heading and Positioning Smart Antenna features the acclaimed Crescent Vector II technology, and provides heave, pitch, and roll output.

The rugged enclosure houses two multipath-resistant antennas for accuracy, portability, and simple installation.

The half-metre antenna mounts easily to a flat surface or pole. The V103 uses WAAS, EGNOS, MSAS for differential positioning and provides GPS heading accurate to 0.3 degrees rms.

Requires a power data cable, available in 15m or 30m.
