Calian TW3972 Triple-Band GNSS Antenna with Accutenna® Technology – Precision Positioning for Demanding Applications
The TW3972 GNSS is a high-performance, triple-band GNSS antenna featuring advanced Accutenna® technology for precision positioning. It supports triple-band signals including GPS/QZSS (L1/L2/L5), GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b), BeiDou (B1/B2/B2a), and NavIC-L5, as well as all regional SBAS systems (WAAS, EGNOS, MSAS, GAGAN) and L-band correction services. This makes the TW3972 ideal for applications requiring reliable, high-accuracy triple-frequency GNSS positioning.
Engineered for train control sensors, autonomous vehicle tracking, precision agriculture, and industrial applications, the TW3972 offers superior multipath signal rejection, linear phase response, and tightly grouped phase center variation (PCV) for consistent, precise results. Its robust design includes a twin circular dual-feed stacked patch element, wide-band LNA, and advanced filtering to minimize interference from LTE and cellular bands.
The TW3972 GNSS antenna meets stringent industry standards, including AAR S9401.V1.0, EN45545-2, EN50121, EN50155, and EN61373, ensuring reliability in harsh environments. Housed in a weatherproof enclosure for permanent installation, it is also available in OEM formats (TW3967, TW3972E) and supports various mounting options for versatile deployment.
