Trimble has launched Trimble VRS Now Ag service for farmers in nine U.S. states — Alabama, Colorado, Florida, Iowa, Illinois, Indiana, Kentucky, Mississippi and Nebraska. As with corrections supplied by conventional Real-Time Kinematic (RTK) radio towers, Trimble VRS network corrections provide sub-inch repeatable Global Positioning System (GPS) accuracy for precision farming operations such as tillage, planting, spraying and field preparation.
The Trimble VRS solution uses proprietary software to create correction models for regions covered by the network. The VRS service can provide growers with instant access to high-accuracy RTK positioning without the need for a local base station. VRS corrections are valuable in areas with natural obstructions such as trees and hilly terrain due to the fact that corrections are obtained by a cellular modem, rather than through the line-of-sight signals provided by an RTK tower.
