    WTRTK-982 RTK positioning module

    Overview


    Product Overview

    1.WTRTK-982 module is the general name of the high-performance BDS/GNSS full-constellation high-precision positioning and orientation module series with a size of 26X38MM.

    2.The module  is all based on the new generation of RF baseband and high-precision algorithm integrated GNSS SoC chip-NebulasIV designed by Unicore Starlink.

    3.The main antenna and the slave antenna simultaneously track the full system frequency points including the Beidou III global signal to achieve on-chip RTK positioning and dual-antenna directional solution.

    4.It has DuaI-RTK dual RTK engine technology and differential input RTCM format adaptive recognition function.

    5.The built-in advanced anti-interference unit ensures that the module can provide reliable and accurate positioning accuracy even in complex electromagnetic environments. 

    For high-precision navigation and positioning fields such as drones, autonomous machines, precision agriculture and intelligent driving

    Features

    1. Small size, gold-immersion process, excellent heat dissipation performance.

    2. Antenna is π-type network impedance matching, standing wave ratio is lower than 2.3, and satellite search performance is strong.

    3. Excellent positioning and orientation function, high sensitivity, 1408 channels, support full-system full-frequency on-chip RTK positioning and dual-antenna orientation solution 

    4. Dual interface: 1. TYPE-C interface, plug and play directly connect to PC to view data. 2. XH2.54x6Pin interface, convenient for embedding into user system equipment. Built-in antenna detection circuit.

    5. Dual antenna input, Dual-RTK dual RTK engine technology, differential input RTCM format adaptive recognition.

    6. Support 3xUART.
