    Here4 Base without antenna

    The Here4 Base (without antenna) isa high-precision GNSS RTK base station module from CubePilot designed for use with drones and autonomous systems. It is a standalone receiver unit that requires an external antenna to function as a reference station for centimeter-level accuracy. 

    MFR Part #: HX4-06312
    $157.50
    Product Overview:
    • Core Hardware: Features the u-blox ZED-F9P chip, a professional dual-band RTK navigation module.
    • Signal Support: Supports multiple constellations including GPS, GLONASS, BeiDou, Galileo, and QZSS across L1 and L5 bands for faster lock times and better accuracy.
    • Compatibility: Fully compatible with ArduPilot and PX4 flight stacks, and integrates seamlessly with ground control stations like Mission Planner and QGroundControl.
    • Connection: Connects to a computer via USB for data and firmware updates.
    • Connectivity Port: Uses a standard SMA connector for attaching the required external L1/L5 antenna. 
    Key Specifications:
    Feature  Details
    Accuracy Horizontal: 0.01 m + 1 ppm; Vertical: 0.01 m + 1 ppm (in RTK mode)
    Weight 18g without cable; 43g with cable
    Size 40 x 41 x 11 mm
    Interface USB (for PC), SMA (for antenna)

     Usage Requirements:

    1. Antenna: Since this SKU does not include an antenna, you must purchase a compatible multi-band (L1/L5) GNSS antenna separately.
    2. Telemetry Link: To transmit RTK corrections from the base to a drone (rover), a separate pair of telemetry radios (e.g., 915MHz or 433MHz) is required.
    3. Setup: Typically configured using the "Survey-In" method in Mission Planner to establish a fixed reference point.
