Don't Guess with GPSGrowers can pick system to match desired accuracy

摘要

Most farmers have a basic familiarity with global positioning systems (GPS) technology. In agriculture, GPS is used to plant and harvest crops and increase efficiency. Picking the right system depends on how accurate you want to be.The current standard system used by agriculture, land surveying and hydrographic surveying is Real Time Kinematic (RTK), also referred to as carrier-wave enhanced GPS. Using base stations and receivers, RTK is common in planting and harvest machinerybecause the accuracy levels are sub-inch. There are several manufacturers with systems that work off RTK signals."For specialty crops, RTK is the way to go to get that sub-inch accuracy," said Mike Martinez, solutions market manager for Trimble Navigation Limited s agriculture division. "The auto-steering options allow growers to plant and harvest without worryingabout ruining crops or missing anything."
