Compact. Precise. Reliable.

The TW1422 is a high-performance embedded GNSS antenna designed with Calian’s proprietary Accutenna® technology, delivering exceptional accuracy and signal integrity. It supports:

  • GPS/QZSS L1
  • GLONASS G1
  • SBAS (WAAS, EGNOS, GAGAN, MSAS)

Key Features

  • High Precision in a Small Form Factor: Ideal for applications requiring accurate positioning and timing where space is limited.
  • Superior Signal Quality: Offers excellent multi-path rejection, a linear phase response, and minimal Phase Centre Variation (PCV).
  • Advanced Antenna Design: Equipped with a 25 mm dual-feed, wideband patch element and a two-stage Low Noise Amplifier (LNA) for optimal performance.
  • Enhanced Interference Protection: Integrated LNA pre-filter shields against high-level sub-harmonic signals (e.g., LTE) and nearby frequency interference (e.g., WiFi).
  • Outstanding Polarization Performance: Delivers a low axial ratio and strong cross-polarization rejection across the full frequency band.

Custom Tuning Available

Calian offers custom tuning services to ensure the TW1422 performs optimally in any OEM installation environment.
