Overview

he TW7929 is a high‑precision, triple‑band GNSS antenna built on advanced Accutenna® technology. It supports GPS/QZSS L1/L2/L5, GLONASS G1/G2/G3, Galileo E1/E5a/E5b, BeiDou B1/B2a/B2b, NavIC L5, regional SBAS systems (WAAS, EGNOS, MSAS, GAGAN), and L‑Band correction services. This design makes it an excellent choice for applications requiring highly accurate triple‑frequency positioning.

Designed for Precision Applications

The TW7929 is optimized for demanding environments where accuracy and reliability are critical, including:

  • Precision agriculture
  • Autonomous vehicle guidance and tracking
  • High‑precision industrial and geospatial systems

Advanced RF Architecture

At its core, the antenna features a dual‑feed circular stacked patch element. Signals from the orthogonal feeds are combined in quadrature, then pre‑filtered through a low‑loss stage to mitigate interference. A high‑linearity, wideband LNA further amplifies the signal before band‑splitting, tight filtering, and final recombination at the output.
This architecture delivers:

  • Exceptional multipath rejection
  • Excellent axial ratio performance
  • Linear phase response
  • Very low phase centre variation (PCV)
  • Robust protection against intermodulation and saturation from strong LTE 700 MHz sources

Rugged, Installation‑Ready Design

The TW7929 is housed in a durable, IP67‑rated, weather‑resistant enclosure with an integrated magnetic mount. For best performance, a 100 mm diameter ground plane is recommended.
