Beitian BT-290 GPS Antenna

Beitian BT-290 GNSS Antenna: High-Gain, Multi-Frequency Solution for Precision Surveying and RTK Applications The Beitian BT-290 GNSS antenna is a high-precision survey antenna designed for various global navigation satellite systems (GNSS), including GPS , GLONASS, BEIDOU, and GALILEO. With a wide voltage range of 3V to 18V, ensuring high gain and exceptional performance in CORS (Continuously Operating Reference Stations) and RTK (Real-Time Kinematic) applications. The antenna supports multi-frequency reception, making it ideal for demanding environments where accuracy is crucial. Featuring a robust TNC-K connector, the BT-290 offers reliable connectivity, making it an excellent choice for professional-grade GNSS applications. High-Precision Multi-GNSS Solution for Surveying and Military Applications The Beitian BT-290 antenna is engineered with a quadrifilar helical structure to efficiently receive signals from multiple GNSS bands, including GPS L1/L2, GLONASS G1/G2, BDS B1/B2/B3, and GALILEO E1/E5b. This design ensures high zenithal gain, strong low elevation gain, and wide-angle circular polarization, contributing to a stable phase center. These features make the Beitian BT-290 antenna ideal for high-precision surveying and positioning across three major GNSS systems. Its versatility makes it well-suited for a variety of applications, including unmanned aerial vehicles, geodetic surveys, road construction, marine surveys, wharf container operations, and border security operations. Advanced Design for Precision and Durability in Challenging Environments The Beitian BT-290 antenna is designed to deliver optimal gain and a superior axial ratio even at low elevations. This structure ensures the alignment of the phase center with the geometric center, minimizing any impact on measurement accuracy. Its wide radiation pattern beam allows for excellent signal reception at low elevations, ensuring reliable performance even in environments with significant obstructions. The antenna is encased in a durable radome that resists extreme temperatures, water, and ultraviolet rays, providing robust protection for continuous outdoor use throughout the year.
