Waterproof IP67 High Precision Centimeter-level 28dB IRNSS NaviC QZSS Glonass Dual Band RTK RTD GNSS Antenna for surveying and mapping
HoneyComm IoT RTK GNSS antenna HGA4741 is designed to receive high-precision satellite signals for real-time kinematic (RTK) positioning. Its main function is to capture multi-constellation signals (GPS, GLONASS, Galileo, BeiDou) with low noise and high gain, ensuring centimeter-level accuracy in navigation and positioning systems. RTK GNSS antennas are widely used in surveying and mapping, precision agriculture, UAVs and drones, autonomous vehicles, smart transportation, machine control, and geospatial data collection. With strong anti-interference capability and stable performance, they are essential for applications requiring high accuracy, low latency, and reliable GNSS positioning.
Overview
With the demands for high precision position, it increases the needs of received GNSS satellites’ number, making thetrend of receiving multi-freguency GNSS system, Choosing a correct antenna is hugely important since antennas are themain interface between the GNSS space segment and the user, especially on multi-frequency system.
HoneyComm Active Antenna HGA4741 is designed by unique technology, covering GPs, BDs, Galileo, GLONASS, IRNSS and QZSssystem, details please refer to table 1. The antenna features stable signal quality and more angle receiver on the practicaconditions. it employs the stack four feeds antenna architecture with hybrid to achieve the multi-frequency operation/lower axial ratio/wider half power beam width and excellent right hand circular polarization.
With the newly architecture,smart transportation, machine control, autonomous driving and surveying and mapping, the active part has two stages, two level LNA, and also one filter for lower band, the other foihigher band. And then, the combiner and the third level LNA output the RF gain to receiver. lt provides excellent noisefiqure/ RF linear and LNA gain and out band rejection, resulting in good signal/noise ratio and anti-interferenceIt is housed in a compact, industrial-grade waterproof and magnet mount enclosure. Using internal magnets, the antennacan be installed almost anywhere allowing for greater flexibility.
