Technical Specifications:

• Model: HEX Here+ RTK Base Module

• GNSS Receiver: U-Blox M8P The Here+ RTK series primarily uses the U-Blox M8P. For newer multi-band RTK, it would be F9P, but "Here+" typically refers to the M8P generation.

• Satellite Systems Supported: GPS (L1), GLONASS (L1), BeiDou (B1), Galileo (E1) - Supports multi-constellation for robust satellite acquisition.

• Positioning Accuracy (RTK):

  • Horizontal: 2.5 cm CEP (with RTK corrections)

  • Vertical: 5 cm CEP (with RTK corrections)

• RTK Communication: Utilizes a radio modem (e.g., SiK radio, typically 915MHz or 433MHz depending on region) for transmitting correction data to the rover module.

• Input Voltage: 5V DC (typically via USB or dedicated power input)

• Interfaces:

  • USB (for configuration via U-Center software, firmware updates, and power)

  • UART (for connection to external radio or other devices)

  • Power/UART/USB ports

• Operating Temperature: -40°C to +85°C

• Protection Level: Generally robust, but specific IP rating might not be official for the ground module.

• Dimensions: 18 × 9 × 5 cm , generally compact for portability.

• Weight: Lightweight for a base station.

• Mounting: Designed for stationary ground deployment (often on a tripod).

• LED Indicators: Status LEDs for power and RTK lock.

Frequently Asked Questions:

Q1. What is the primary purpose of an RTK Base Module like the HEX Here+ for drones?

Ans. The primary purpose of an RTK Base Module like the HEX Here+ is to act as a stationary reference point on the ground that receives satellite signals and calculates correction data for precise positioning. It then transmits these corrections wirelessly to the drone's RTK GPS module (rover). This real-time correction process allows the drone to achieve centimeter-level positioning accuracy, far superior to standard GPS, which is crucial for highly precise applications like surveying, mapping, and automated agricultural tasks.

Q2. How does the HEX Here+ RTK Base Module communicate with the drone's RTK GPS module?

Ans. The HEX Here+ RTK Base Module typically communicates with the drone's RTK GPS module (the "rover") via a radio modem link. The base module uses its integrated radio (often a SiK radio operating on specific frequencies like 915MHz or 433MHz, depending on regional regulations) to transmit the calculated RTK correction data wirelessly to the corresponding radio on the drone. This allows the drone's GPS receiver to correct its own position in real-time, achieving high accuracy.

Q3. Is setting up the HEX Here+ RTK Base Module complex, and does it require special software?

Ans. Setting up the HEX Here+ RTK Base Module involves connecting it to a computer via USB and using a dedicated software tool, typically U-Center (from U-Blox), for initial configuration and firmware updates. While not overly complex, it does require some understanding of GNSS settings and radio communication parameters. Once configured, it's typically deployed in a clear, open area with a stable power source. For integration with drone flight planning software, it generally plugs directly into the workflow (e.g., Mission Planner or QGroundControl for ArduPilot systems)
