Excellent Anti-interference Performance

Small Form Factor with Foldable Design

IP65 Rating Waterproof

High Phase Center Stability

The V3Novus V3N-GGI-107 Helical Antenna offers full support for reliable and consistent satellite signals tracking, including GPS, GLONASS, Galileo and BeiDou, IRNSS-L5 as well as L-Band. It also exhibits a very stable phase center by adopting multipoint feeding technology, exceptional low elevation satellite tracking with symmetric radiation patterns, high gain with ultralow signal loss, as well as outstanding wide-angle circular polarization (WACP) ensures remarkable positioning accuracy.

Tracking In Challenging Environments

The V3Novus V3N-GGI-107 is able to track any visible satellites under challenging conditions, providing the positioning solutions with higher precision and reliable data. The ability to track low elevation satellites while maintaining high gain makes this antenna an excellent choice for any applications where the sky is partially visible, such as plant protection, tree canopy, or for UAV power patrol, Handheld Terminals, GIS surveying where high precision is needed.

Strong Anti-Interference Performance

The advanced LNA (Low Noise Amplifier) excels in improved signal filtering and out-of-band rejection and restraints unwanted electromagnetic interferences, plus strong multi-path reduction capacity over all GNSS frequency bands, providing strong anti-interference performance for consistent and reliable GNSS signals, even under complicated environments such as power grids, communication base stations or Handheld radio.

Small Form Factor Foldable Design

V3N-GGI-107 adopts a rugged small form factor foldable design that allows a maximum of 90 degree bending angle, providing the most flexible GNSS signal reception angle for robust signal availability of the surveying control terminals. This foldable design ensures reliable performance even after long-term repeated bending operations
