About Products

RTK High-Precision Positioning Antenna


Core Advantages: Designed specifically for the Global Navigation Satellite System (GNSS), it supports multi-system and multi-band signal reception for GPS, Beidou, GLONASS, and other systems. Combined with RTK algorithms, it achieves centimeter-level real-time positioning, providing stable and reliable signal support for high-precision scenarios.


Performance Highlights:


High-gain design (gain ≥ 30dB) + low-noise amplifier (LNA) enhances weak signal reception, reduces interference, and ensures pristine signal purity.


Built-in multipath mitigation technology (such as a choke coil structure) reduces interference from ground reflections and building obstructions, ensuring more stable positioning in complex environments.


Industrial-grade protection (IP65 and above) withstands temperatures ranging from -40°C to 85°C, vibration, and other harsh environments, ensuring worry-free outdoor operation.


Applications:


Engineering surveying and mapping, road and bridge construction stakeout, precision agriculture (autonomous agricultural machinery, variable-rate fertilization), drone navigation (surveying/inspection), dam and bridge deformation monitoring, and other applications requiring extremely high positioning accuracy.
