        FAQ Section<\/h3>\n<\/div>\n
        \n
        Q1: Which flight controllers are compatible with VK-FLY D3-H RTK heading module?
        \n<\/strong>A: It achieves plug-and-play seamless connection with VK-FLY V10-PRO industrial flight controller; it also supports secondary development docking with all autopilots that comply with MAVLink protocol.<\/div>\n<\/div>\n
        \n
        <\/div>\n
        Q2: How accurate is the heading measurement of D3-H?
        \n<\/strong>A: When the baseline distance of dual antennas reaches 30cm or above, the heading angle error is less than 0.3\u00b0, effectively solving magnetic compass interference problems of large industrial drones.<\/div>\n<\/div>\n
        \n
        <\/div>\n
        Q3: Can D3-H work stably under high temperature of 30\u201334 degrees Celsius?
        \n<\/strong>A: Yes, the module is equipped with independent heat dissipation aluminum shell, designed for stable continuous operation at 30\u00b0C to 34\u00b0C ambient temperature, no positioning drift or signal loss in high-temperature farmland and open-air environments.<\/div>\n<\/div>\n
        \n

        Q4: What\u2019s the difference between D3-H and ordinary single GNSS modules?
        \n<\/strong>A: Single GNSS only outputs position data without heading angle; D3-H dual-antenna design synchronously provides high-precision position and real-time heading, which is essential for VTOL and large multi-rotor industrial drones.<\/div>\n<\/div>\n
        \n
        <\/div>\n
        Q5: Does D3-H support mobile dynamic RTK without fixed base station?
        \n<\/strong>A: D3-H has dual working modes, including mobile dynamic takeoff & landing mode, which can complete differential positioning without ground fixed RTK base station, more convenient for field mobile survey.<\/div>\n<\/div>\n
