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.
