Benefits and Performances

Multi-constellation Tracking
The AT311T supports all current and future GNSS signals, including GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, SBAS, and L-Band. Its multi-feed point design ensures the phase center aligns with the geometric center, minimizing measurement errors and enhancing accuracy.

Superior Performance
With 40 dB signal gain, advanced signal filtering, and a multipath rejection design, the AT311T delivers superior GNSS signal tracking in challenging environments. Its high-gain, wide-beam pattern ensures effective reception of low-elevation signals, enabling signal acquisition even in obstructed areas.

Ruggedized Design
The AT311T features an IP68 water-resistant design, making it suitable for extreme conditions across a wide operating temperature range. The metal ground plane and high-strength enclosure provide superior drop resistance compared to traditional plastic-made GNSS antennas.
