How To Do Software Calibration and Set Up RTK Signal for Sveaverken F100?

How To Do Software Calibration and Set Up RTK Signal for Sveaverken F100?

 In our previous blog post, we introduced a quick guide to installing the Sveaverken F100 tractor GPS system. Today, we will explain the process of software calibration and setting up the RTK signal for our newly installed tractor GPS system. Let's get started.

Prerequisites for Software Calibration

To ensure a smooth software calibration and RTK setup process, follow the prerequisites first:

1. Installation is complete and in accordance with specifications.

2. The environment is open, without interference or obstructions.

3. Ensure a minimum of a 50-meter flat, straight stretch of road for calibration.

4. Network connectivity is available via 4G, WiFi, or other means for receiving data.

5. There is an account available for registration.

6. Select a correction source you want to use.

Comprehensive Software Calibration Guide

Step 1: Measure Vehicle Parameters

After the tractor GPS system installation, accurately measure the vehicle parameters including front wheel track, front to rear wheelbase, distance from the rear axle to hardpoint, and GNSS Receiver height to improve the accuracy of the system's model calculations.

Step 2: Calibrate Angle Sensor

After entering the angle sensor setting page, you need to choose the type of sensor - Hall Sensor, Attitude Sensor, or No Angle Sensor. If you choose the first two types, select the installation position for the sensor. If the angle sensor type is set to "No Angle Sensor", enter the steering speed ratio and maximum steering.

Step 3: Vehicle Calibration

The initial vehicle attitude data may affect operation accuracy, resulting in a significant offset. The vehicle calibration dynamically corrects the error. Tap Vehicle Calibration in the Parameter Settings and choose "Start Calibration" to begin. Then, you need to follow the displayed steps for specific calibration operations.

Step 4: Calibrate GNSS Receiver Distance

There may be errors in the tractor GPS system's calculation of the vehicle's center position. Manual calibration and adjustment of parameters are done to correct the center point position.

Step 5: Set the Working Width

Click on the "Working Width Alert" in the parameter settings. Enter the value of the working width, which is the desired row spacing reserve width plus the working width.

Step 6: Implement Calibration

After the calibration of the GNSS Receiver distance is completed, adjustments are needed if there are deviations in the implement mounting position or if the overlap during operations does not meet requirements.

Mastering RTK Signal Setup

Connecting to satellites is a major challenge during setup. You can connect to three correction sources: Mobile RTK Base Station, Network RTK, and SBAS.

1. Mobile RTK Base Station

You can purchase a Sveaverken RTK Base Station and pair it with a radio station for a centimeter-level correction source. Then you will obtain lifetime access to the RTK signal.

2. Network RTK

If a nearby CORS base station and a local Ntrip account are available, you can establish an RTK connection through the network. To use this mode, ensure that you are connected to the network first.


In this mode, the autosteering kit receives differential data from the SBAS system to achieve differential positioning. Please note that the positioning precision in this mode is much lower.

Note: To use SBAS, you will need to purchase the hardware version that includes SBAS and upgrade it to V3.1.3 or a later version.

To achieve high-precision farming with the F100 tractor GPS system, you should connect to RTK signals. As for some suggestions about how to choose RTK sources, you can check our related blog: How to Choose NTRIP or RTK Base Station with Auto Steer System?
