Own Your RTK Network: Cloudbase Cellular RTK vs Radio vs SF-RTK Comparision

Understanding RTK and Your Options

RTK (Real-Time Kinematic) gives your guidance system sub-inch accuracy by sending correction data to your receiver. Without it, even a good GPS receiver drifts. There are three main ways farmers get those corrections today:

1. Radio RTK (the traditional method) A base station on a tall tower or grain leg broadcasts corrections over a 450 MHz or 900 MHz radio. Your machine needs a matching radio to receive the signal.

It works, but it is line-of-sight. Trees, rolling ground, and distance weaken or kill the signal. That’s why radio networks need tall towers and repeaters — and why many farmers still lose RTK in a back corner and watch the light bar go amber mid-pass. Most dealers also charge an annual network access fee (commonly around $2,000/year in our area, though it varies) plus the cost of a radio on every machine.

2. John Deere SF-RTK (satellite-delivered) Corrections come down from the satellite itself. No local base station or radio is required, and performance is solid.

The business model is the issue: roughly $1,500 per receiver, per year, every year. Four receivers means a $6,000 annual check. Stop paying and the accuracy disappears. You are renting the signal.

3. Cellular RTK (what CloudBase delivers) The same correction data travels over the 4G LTE network your phone already uses, using a standard protocol called NTRIP. A small CloudBase modem attaches to your receiver, pulls the corrections over cellular, and feeds them in.

Because cellular coverage does not require line-of-sight, there is no tower to build, no repeaters, and no radio shadow behind the woods.

Three Ways to Get Corrections with CloudBase Cellular RTK

Your CloudBase modem can receive corrections from any of these sources:

  • Free (or low-cost) state CORS networks Indiana’s InCORS network (and similar networks in Ohio, Michigan, and many other states) provides RTK corrections at no charge. The modem ships with its cellular SIM installed, and there’s no CloudBase annual fee on free CORS. This is the lowest-cost way to run Cellular RTK and works well for many farms.

  • Paid cellular correction services Providers such as RTKData sell NTRIP subscriptions. You pay a monthly or annual fee for access to their correction stream over cellular. Good option when free CORS coverage is weak or unavailable.

  • Your own CloudBase Cellular RTK Base Station One base mounted at your shop or a central location covers roughly a 30-mile radius and serves every machine you own — any brand, any color — with the highest accuracy available (up to sub-quarter-inch repeatability). You own the network.

    This is the most accurate and most reliable option, especially on larger farms or ground with challenging terrain.

The CloudBase Cellular RTK Hardware

The system has three core products:

  1. CloudBase Cellular RTK Base Station – Your private on-farm correction source with a 30 mile coverage radius, fully supported, and will provide the highest accuracy year over year.
  2. Cloudbase Cellular RTK Modem – John Deere – Bolt-on modem made for StarFire 3000 / 6000 / 7000 / 7500 receivers.
  3. Cloudbase Cellular RTK Modem – Universal – Works with almost any RTK-ready receiver (Case IH, Trimble, Raven, Ag Leader, CNH, and others).

How it works simply A base (your own, a free CORS station, or a paid service) generates precise corrections and sends them over the cellular network. Each machine’s CloudBase modem receives those corrections and feeds them to the receiver in real time. No radio programming, no line-of-sight issues, and no per-machine satellite subscription for the correction stream itself.

How Easy Is It to Put on Your Farm?

  1. Choose your correction source (free CORS, paid service, or your own base).
  2. Mount the modem — the John Deere version bolts to the back of a StarFire in about 30 minutes; the Universal version includes your specific receiver harness for plug and play and connects via the receiver’s serial/NTRIP port.
  3. The cellular SIM is already installed, and we configure the modem before it ships. Most setups take under 30 minutes.
  4. Select the correction source on the modem.
  5. Go to the field. The receiver shows 3D RTK and you are ready for AutoTrac, section control, or any other precision application.

Coverage depends on local cellular service, which is strong across most of the Midwest corn and soybean belt. We offer a free coverage check on your actual ground before you buy anything.

Honest Cost Comparison

  • Modem: $2,000 one-time, cellular SIM included. Run it on free CORS with no CloudBase annual fee, or join the CloudBase Network for $499/year per modem (SIM, live monitoring and remote support).
  • Base Station: $10,000 installed and commissioned by us — no annual base fee. Each modem on it runs on the CloudBase Network at $499/year.

Installation reality The modem is a genuine 30-minute bolt-on job with basic hand tools. We are a phone call away if you want walk-through help on the first one.

The base station is different — the $10,000 price is fully installed. We come to your farm, select the mount point, survey the fixed position, connect power and internet, commission the network, and get your first modem online before we leave. It includes the enclosure, GNSS and cellular antennas, 65 ft of pre-terminated coax, and a UPS battery backup so a short power blip does not stop planting.

Frequently Asked Questions

Do I need perfect cell service in every field? You need usable 4G LTE where you farm. Correction data is tiny — far less than a phone call — so modest signal is usually enough. We will run a free coverage check on your ground first.

What happens if the cell network or my internet drops? The receiver continues on its last corrections and standard GPS. Accuracy degrades gradually rather than disappearing instantly. The base station’s battery backup rides through short power outages at the shop.

Is Cellular RTK as accurate as radio RTK or SF-RTK? It uses the same RTK mathematics — the corrections just travel a different path. Expect the sub-inch, repeatable accuracy RTK is known for. Your own CloudBase base delivers the highest performance (up to sub-quarter-inch repeatability).

Are there long-term contracts? No. You own the hardware. The CloudBase Network ($499 per modem per year) covers the SIM, live monitoring on the CloudBase platform, and our support — that is the complete story. Own your own base and there is no annual fee on the base itself.

What if it doesn’t work out on my farm? Everything carries a 60-day money-back guarantee. Every unit is tested on our own farm in Frankfort before it ships.

The Bottom Line

Subscriptions are fine until you add up the checks. Paying $1,500 per receiver every year means you will spend the cost of a base station every couple of years and still own nothing.

Cellular RTK flips that model: buy the hardware once, pay a small honest support fee, and keep the difference — every year, on every machine.

Start with free CORS or a paid service if that fits your budget. Move to your own CloudBase base station when you want the highest accuracy, full control, and the lowest long-term cost on a larger fleet.
