GNSS RTK GPS Waterproof Full-Band High Precision GNSS RTK Measurement External Antenna Satellite Navigation

<ul><li>New and high quality. Made of high-quality materials, .</li><li>The external all-band GNSS measurement antenna supports the satellite navigation signal reception of Beidou, GPS and GLONASS systems, meets the current requirements of multi-system compatibility and high-precision measurement, and can be widely used in geodesy, oceanographic measurement and precision agriculture, deformation monitoring and other high-precision navigation and positioning occasions.</li><li>The antenna unit has high gain and small gain rolling, which has a good reception effect on low-altitude satellite signals and ensures that satellites can still be received normally in some severely blocked situations.</li><li>Full-frequency high-precision external antenna.</li><li>The antenna adopts a single-layer multi-feed point ultra-wideband design to minimize the phase center elevation difference of the entire working frequency band.</li></ul>

Low-noise amplifiers use pre-filtration technology to effectively suppress out-of-band interference with Nals and improve the reliability of the system. Passive network path suppression technology effectively reduces the impact of multi-path signals on measurement accuracy. The waterproof and ultraviolet cover protects the antenna from working on for a long time. Support satellite signals:BDS: BI, B2. B3: GPS: L1, L2, L5: GLONASS: , G2. G3: : El, E2, F5a. ESh.
