RTK communication solutions for precision farming

Precision Farming is one of the key technologies in the area of Smart Farming. As a management system, it makes use of modern technologies to improve efficiency like optimal allocation of resources and utilization of machines. To keep vehicles on track, Real Time Kinematic (RTK) is the first choice to determine geographical positions and so ensuring accuracy, repeatability and optimal signal build time.  

 

Smart Framing RTK

RTK is the best solution to keep agricultural machines on track.

RTK technology for precision farming

As an approach for the precise determination of position coordinates, RTK makes use of satellite navigation methods to eliminate track drifts. The RTK station has fixed coordinates and tracks the constellation of the GPS satellites. From this position the station continuously calculates and sends a correction signal (in real-time) to the relevant agricultural machine to compensate errors of the received GPS signal. The data transmission is done over 5G and LTE with the Ntrip protocol or via private UHF Radio. In this way the position of the machine can be determined with centimetre accuracy. 

Advantages of RTK for precision farming:   

  • Increased efficiency by field through less overlapping 
  • Saving of operating recourses, e. g. fertilizer  
  • Possibility to extend field work hours, e. g. at night 
  • Fuel savings through optimized machine utilization 
  • Constant driving performance, also under poor visibility conditions 

Welotec RTK Modems for precision farming 

We develop and produce modems for transmitting GPS/GNSS correction data in real time. The so-called RTK modems work with various forms of technology such as 5G, LTE or 869 MHz data transmissions. Through precise positioning with up to 1cm accuracy, agricultural machinery can not only drive automatically, but also apply consumables with optimal dosage for the current soil conditions.
