The Right GPS Correction Service Can Stop Dropped Signals


GPS-guided farm equipment can suffer from dropped signals while doing field operations due to a number of factors, including hills and buildings that block signals. Waiting for a signal’s return slows down productivity and decreases return-on-investment for receivers.

To fix this problem, consider using a correction service such as the Trimble CenterPoint RTX.

CenterPoint RTX correction service delivers GNSS-enabled, repeatable 1.5-inch (3.8 cm) corrections via cellular network directly to a receiver anywhere in the world. CenterPoint RTX works with the built-in GNSS receiver in an existing Trimble FmX integrated display, CFX-750 display, or AG-372 GNSS receiver. The service allows farmers to continue working during times of correction signal loss for up to two minutes.

gpsCenterPoint RTX converges to full accuracy in 30 minutes or less. Positions may be used much sooner at a lower accuracy level—the farmer decides, depending upon precision requirements. You can decrease the standard initialization time to less than five minutes at the beginning of each day by starting your tractor in the same place you shut it off the night before.

The service is available throughout the world over mobile data network, or all of Latin America and portions of North America via satellite delivery.

(For farms that use an RTK solution and are within eight miles of a base station without line-of-sight obstructions, Trimble offers CenterPoint RTK.)

The company recommends interested farmers consider these questions when shopping for a correction service:

  • What level of accuracy does your farming application require?
  • Where are you located?
  • Do you have reliable cellular coverage in your area?
