2. Setup Instructions

Proper setup is crucial for optimal performance of your RTK GNSS Active Antenna. Follow these steps carefully:

1. Mounting Location: Select a mounting location with a clear, unobstructed view of the sky. Avoid areas near large metal objects, buildings, or other structures that could block satellite signals or cause multipath interference. The antenna should be mounted as high as practically possible.
2. Secure Mounting: Securely attach the antenna to a stable, non-moving surface. Ensure the antenna is oriented vertically with the top facing upwards. Use appropriate mounting hardware (not included) to prevent movement due to wind or vibration.
3. Cable Connection: Connect the antenna's coaxial cable to the designated GNSS receiver port. Ensure the connection is tight and secure to prevent signal loss. Avoid bending the cable sharply or placing it under tension.
4. Power Supply: The active antenna requires power, typically supplied by the GNSS receiver through the coaxial cable (phantom power). Verify that your GNSS receiver provides the necessary voltage (e.g., 3.3V to 5V DC) to power the antenna. Refer to your receiver's manual for power output specifications.
5. Initial Check: After connecting, power on your GNSS receiver and check for antenna detection and signal acquisition. Most receivers will indicate antenna status and satellite visibility.

3. Operating Instructions

Once the antenna is properly set up, follow these guidelines for effective operation:

1. Clear Sky View: Always ensure the antenna has an unobstructed view of the sky. Any blockage can degrade signal quality and positioning accuracy.
2. Receiver Configuration: Configure your GNSS receiver according to the specific requirements of your application. This may include selecting the desired satellite constellations (GPS, GLONASS, BDS, Galileo) and RTK correction sources.
3. Signal Monitoring: Monitor the signal strength and satellite tracking status on your GNSS receiver. A strong signal-to-noise ratio (SNR) and a high number of tracked satellites indicate good reception.
4. RTK Corrections: For RTK (Real-Time Kinematic) operations, ensure that RTK correction data is being received and applied correctly by your GNSS receiver. This data is essential for achieving centimeter-level accuracy.
5. Environmental Factors: Be aware that environmental conditions such as heavy foliage, dense urban areas, or severe weather can affect GNSS signal reception.

4. Maintenance

To ensure the longevity and consistent performance of your RTK GNSS Active Antenna, follow these maintenance recommendations:

• Regular Cleaning: Periodically clean the exterior of the antenna with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the housing.
• Inspect Cables and Connectors: Regularly inspect the coaxial cable and connectors for any signs of wear, damage, or corrosion. Damaged cables can lead to signal degradation.
• Environmental Protection: While designed for outdoor use, protect the antenna from extreme environmental conditions when not in use, if possible. Ensure seals and covers are intact to prevent water ingress.
• Secure Mounting: Periodically check that the antenna remains securely mounted and that all mounting hardware is tight.

5. Troubleshooting

If you encounter issues with your RTK GNSS Active Antenna, consider the following troubleshooting steps:
