V102 GPS Compass Series
General Navigation Heading and Positioning Smart Antenna
Experience superior navigation from the accurate heading and positioning performance available with the V102™ GPS
compass. The V102 uses SBAS (WAAS, EGNOS, MSAS, etc.) for differential GPS positioning allowing Hemisphere GPS
to provide a low cost and highly effective heading and position based smart antenna.
The rugged and low profile enclosure combines Hemisphere GPS’ Crescent® Vector™ II OEM technology and two
multipath-resistant antennas for accuracy, portability and simple installation. The smart antenna - measuring less
than half-meter length - mounts easily to a flat surface or pole. The stability and maintenance-free design of the V102
provides traditional GPS positioning and heading at a low cost.
Key V102 GPS Compass Series Advantages
• Provides heave, pitch and roll
• Excellent in-band and out-of-band interference rejection
• 0.75 degree heading accuracy in amazingly small form factor
• Extremely quick time-to-first-fix
• Submeter DGPS positioning accuracy
• Integrated gyro and tilt sensors deliver fast start-
up times and provide heading updates during temporary loss of GPS
• SBAS compatible (WAAS, EGNOS, MSAS, etc.) and optional external differential input
• COAST™ technology maintains differentially-
corrected positioning for 40 minutes after loss of differential signal
