High-Precision, Single-Band GNSS Performance in a Compact Form Factor
Overview
The TW1430 is a high-performance embedded GNSS antenna that leverages Calian’s proprietary Accutenna® technology. It supports GPS/QZSS L1, GLONASS G1, and SBAS (WAAS, EGNOS, GAGAN, MSAS), delivering exceptional accuracy and signal integrity in a compact design.
Key Features
- Accutenna® Technology for superior multipath rejection
- Compact 25mm dual-feed wideband patch element
- Two-stage Low Noise Amplifier (LNA) for enhanced signal clarity
- Excellent axial ratio and cross-polarization rejection
- Linear phase response and tight Phase Centre Variation (PCV)
Ideal Applications
Designed for systems requiring high-precision positioning and timing in space-constrained environments, the TW1430 is perfect for:
- Precision agriculture
- Autonomous systems
- Timing synchronization
- OEM GNSS modules
Customization & Integration
Calian offers custom tuning services to optimize antenna performance for specific OEM installation environments, ensuring maximum efficiency and reliability.
Enhanced Gain Option
The TW1430 is a higher gain alternative to the TW1421, specifically engineered to meet the needs of receivers requiring increased signal strength—such as the Trimble BD9xx series.
