How are GPS systems installed?

Typically, agricultural GPS guidance systems are installed two different ways: factory pre-wired and aftermarket. Factory wiring for GPS guidance systems is included on many newer agricultural vehicles and equipment. GPS guidance systems are connected into the factory wiring harness and typically use factory mounts for the display and antenna. These systems tend to be plug-and-play, when used with similar branded equipment. Many additional features may be available by integrating with the vehicle electronics such as vehicle diagnostic data, implement control or automatic steering.

What are GPS coordinates used for?

Most of this information is commonly tied to the location where it was collected. GPS coordinates are the most common way producers determine this location, so selecting the proper GPS system for the job is critical. Whether a producer has not used a GPS systems and wants to find an affordable entry level guidance system or wants to upgrade to the latest model with all the bells and whistles, there are many different things that should be considered when selecting a new system.

How is GPS repeatability measured?

Repeatability or static accuracy is measured as the GPS receiver’s ability to return back to a point measured more than 15 minutes ago . Typically, static accuracy is measured by collecting position data over a minimum of 24 hours.

What is GPS accuracy?

The accuracy of a GPS guidance system plays an important role in providing proper guidance to agricultural equipment. Many manufacturers list the rated accuracy of their system in the equipment specifications, but what does that mean, exactly? Most guidance systems are concerned with position accuracy, which is the difference between the measured position of the unit and the true position of the unit. Position accuracy can be measured in many different ways, but the three standard terms related to GPS guidance systems are absolute, pass-to-pass (relative) and repeatability (static).

How accurate is a subscription augmentation system?

Many of the lower- cost options may not give much more pass-to-pass accuracy than the public augmentation systems, but increase the static accuracy to reduce in-season position drift. Subscription costs for these services can range from a couple hundred to a couple thousand dollars each year. There are several different services available such as Trimble RTX, OmniStar, Starfire, etc. Each agricultural equipment manufacturer will offer one or more of these services. Each service offers multiple pricing tiers ranging from a static accuracy of 1.2 to 20 inches with 1.2- to 6-inch pass-to-pass accuracy. Position data collected using these services are usually good for in-season use only or operations no further than 9 months apart.

How accurate is GPS?

If the pass-to-pass accuracy of a system is 6 inches, then the GPS system should be able to return to within 6 inches of that point if no more than 15 minutes has passed since measuring the point originally. Pass-to-pass accuracy is the most commonly presented accuracy by equipment manufacturers because it is the most important for swath guidance. Figure 1 presents an example of an implement return pass using a 30-foot swath. Since the second pass is completed usually within 15 minutes of the first, the error should only be the pass-to-pass error (6 inches).

Where is correction signal broadcast?

Correction signals are broadcast from a base station or stationary GPS receiver within 12 miles of the vehicle guidance system. A local base station can be setup along a field border or at a nearby building/tower.
