Base Station: Location requirements

To achieve optimal accuracy and reliable operation from the base stations, ensure all five of the following requirements are met:

1. Clear sky view
2. Stable, immovable anchoring point
3. Sufficient distance from solar panels
4. Sufficient distance from metal roofs
5. Adequate GSM signal strength

1. CLEAR SKY VIEW

A clear sky view means there are no obstacles within a 30° angle above the antenna’s position, as shown in the illustration below.

For optimal performance, install the GPS antenna at a high point, such as the edge of a building, placing it above the roof ridge, trees, silos, or other potential obstacles. Avoid mounting the GNSS antenna near chimneys, as chimney smoke can cause signal interference.

2. STABLE, IMMOVABLE ANCHORING POINT

To secure the GNSS antenna properly, the mounting surface must be stable and immovable, ensuring it remains unaffected by strong winds or adverse weather conditions.

Therefore, do not install the base station’s GNSS antenna on masts, chimneys, or towers.

3. SUFFICIENT DISTANCE FROM SOLAR PANELS

Make sure the GNSS antenna is not placed near solar panels, as reflected signals from solar arrays can disrupt satellite communications and reduce positioning accuracy.

Refer to the images below for visual guidance:

4. SUFFICIENT DISTANCE FROM METAL ROOFS

Do not mount the GNSS antenna on metal roofs or the sides/tops of containers, as flat metal surfaces can reflect satellite signals, causing instability in the GNSS receiver.

If installation on a metal roof is unavoidable, position the antenna on the highest point to minimize signal reflection.

5. ADEQUATE GSM SIGNAL STRENGTH

To verify robust communication between the robot and the RTK Base Station, conduct initial internet connectivity tests at both the intended robot operating area and the chosen Base Station location.

Using a smartphone, perform an internet speed test by following these steps:

1. Install a “Speed test” application on your smartphone, or visit: https://www.speedtest.net/
2. Run the internet speed test at both the intended robot operating field and the planned Base Station location.
3. Review the download speed results to determine if the connection meets requirements or if further testing is needed:
   1. If the download speed is above 1 Mbps, the internet connection is considered sufficient.
   2. If the speed is below 1 Mbps, further testing and troubleshooting are required.

The following illustration demonstrates how to conduct field testing:

If you experience connectivity issues in your area, contact your local distributor for guidance on the following solutions:

1. Extended range GSM antenna (UPG07V2.0-2.3): This accessory enhances GSM connectivity in remote locations and includes a 4-meter cable, allowing the antenna to be mounted externally for optimal signal reception.

2. Connect the Base Station to Internet through your home/office router: This method is most effective when the Base Station is installed near your home or office.
