Using GPS technologies in modern farming is not a surprise. It is efficient and convenient to operate all the farming machinery with it. Besides, GPS helps much to get necessary info about the relief, weather, humidity level on-site. Between the major principles of precision AG, GPS use is in leading positions worldwide.

But there is one thing that should be mentioned when using GPS. Its signals when getting from satellites to your receiver can be distorted due to the atmosphere refraction, weather conditions and even local radio signals. To avoid this, a special RTK GPS receiver is required.

This device receives corrections for GPS signals from the RTK stations both private or state NTRIP. Collecting high-precision geospatial data on your smartphone or tablet has never been easier as it is when using an RTK GNSS receiver.

How Does RTK GNSS Reciever Work?

GPS GNSS receiver for tractors looks like quite a simple device that can be placed on the roof of the vehicle. Then, you may need to connect it with your GPS app to create a stable system.

When you get signals from GPS satellites, your RTK receiver gets that signal first, connects to the RTK station nearby and makes corrections in the signal to provide the highest accuracy within 20-50 cm depending on the type of receiver.

There are two basic options used for tractors:

·  L1-type RTK GPS receiver that suits working on flat spaces without considerable landscape diversity. These items are cheaper yet they can fully maintain basic needs in RKT corrections. The accuracy of these receivers is 30-50 cm on average in a standalone device reducing to 2 cm with RTK corrections.

·  L2-type RTK receiver for GPS is a more expensive solution that allows minimizing distortion even in a hilly landscape. Its standalone accuracy is 20-30 cm reducing to 1 cm when connecting to the RTK station.

Both GPS GNSS receivers are useful for your farming goals starting with fieldwork up to analyses of all the works over the season. To choose among these two options, you need to consider the type of landscape on your farm, the distance to the nearest RTK station (as for L1, the distance of transmission and receiving is about 10 km via the Internet vs 20 km via the Internet for L2 RTK receiver). One more thing that should be also considered is the time to receive the first signal for correction.

Keeping all these in mind, you’ll be eager to choose the type of RTK GPS receiver that will be the most effective for your farm. No matter to say, you definitely need it for your precision farming activities.
