4. Setup Guide
4.1 Initial Charging
Before first use, ensure all battery units (Rover, Base, Controller) are fully charged. Connect the provided recharger and USB cables to the respective devices and a power source. The LED indicator on the devices will show charging status.
4.2 Assembling the Rover/Base Units
- Attach the UHF antenna to the designated port on the Rover/Base unit.
- Mount the Rover/Base unit onto a surveying pole or tripod, ensuring it is stable and level.
- For the controller, attach it to the bracket and secure it to the surveying pole for easy access during operation.
4.3 Powering On and Connectivity
- Press and hold the power button on the Rover/Base unit until the LED indicators illuminate.
- Power on the controller.
- Establish communication between the controller and the Rover/Base unit via Bluetooth. Refer to the controller's specific manual for detailed pairing instructions.
- Ensure the Rover/Base units have a clear view of the sky for optimal satellite signal reception.
4.4 Software Installation and Configuration
The V300 system typically uses the 'Hi Survey' software. Install the software on your controller or compatible device. Follow the on-screen prompts to configure the system, including:
- Project creation and coordinate system settings.
- RTK mode configuration (Base/Rover roles, communication method - e.g., internal radio, external radio, network RTK via 4G/eSIM).
- NTRIP protocol settings if using network RTK.
5. Operating Instructions
5.1 Basic Operation Modes
- RTK (Real-Time Kinematic) Mode: Provides centimeter-level accuracy in real-time. Requires a Base station (either another V300 or a reference station) transmitting corrections to the Rover.
- Static Mode: Used for high-precision post-processing. Collect raw GNSS data over a period, then process it with data from a known reference station.
- DGPS (Differential GPS) Mode: Offers sub-meter accuracy using differential corrections.
- SBAS (Satellite-Based Augmentation System) Mode: Improves GPS accuracy and integrity using satellite-broadcasted corrections.
5.2 Data Collection
- In the 'Hi Survey' software, select your desired survey method (e.g., Point Survey, Stakeout, Line Survey).
- Ensure stable satellite lock and RTK fix (if in RTK mode). The LED indicators on the V300 unit will confirm signal status.
- Follow the software's instructions to record points, lines, or other survey features.
- Utilize the tilt measurement function for accurate measurements even when the pole is not perfectly vertical. The system automatically compensates for tilt up to 60 degrees.
5.3 Advanced Features
- NFC Flash Link: Use NFC for quick pairing and connection with compatible devices.
- WebUI Interaction: Access the V300's settings and status via a web interface using a browser on a connected device.
- Image Lofting: The professional star night vision HD camera supports real-scene lofting, allowing for visual guidance during stakeout or data collection.
- Intelligent Voice: Provides real-time voice prompts and feedback during operations.
6. Maintenance
6.1 Cleaning and Storage
- Regularly clean the exterior of the V300 units and controller with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Ensure all ports are free from dust and debris.
- When not in use, store the instrument and accessories in their original carrying cases in a dry, temperature-controlled environment (-55℃ to +85℃).
6.2 Battery Care
- Recharge batteries regularly, even during periods of non-use, to maintain battery health.
- Avoid fully discharging the batteries frequently.
- Use only the provided recharger and USB cables.
6.3 Firmware Updates
Periodically check for firmware updates for both the V300 units and the controller software. Updates can be performed via USB flash drive or online through remote service features, improving performance and adding new functionalities.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No satellite signal / Poor signal quality | Obstructions (buildings, trees), poor antenna connection, unit not powered on. | Move to an open area. Check antenna connection. Ensure unit is powered on and has a clear view of the sky. |
| No RTK fix | No corrections from Base, poor radio link, incorrect Base/Rover settings. | Verify Base station is transmitting. Check radio frequency and protocol settings. Ensure sufficient distance between Base and Rover for radio link. Check network connection for NTRIP. |
| Controller not connecting to V300 unit | Bluetooth off, incorrect pairing, low battery. | Ensure Bluetooth is enabled on both devices. Re-pair the devices. Charge batteries. |
| Unit not powering on | Low battery, faulty battery, power button issue. | Charge the battery. Try a different battery if available. Contact support if issue persists. |
| Inaccurate measurements | Poor satellite geometry, multipath, incorrect calibration, tilt not compensated. | Wait for better satellite geometry. Avoid reflective surfaces. Perform calibration. Ensure tilt compensation is active. |
8. User Tips
- Pre-plan your surveys: Before heading to the field, plan your survey points and check satellite availability for your location and time.
- Keep software updated: Regularly update the 'Hi Survey' software and V300 firmware to benefit from the latest features and performance improvements.
- Monitor battery levels: Always start your fieldwork with fully charged batteries and carry spares if possible, especially for long survey sessions.
- Secure connections: Ensure all cables and antennas are securely connected to prevent signal loss or damage during operation.
