Differential GPS as Used in the Agriculture Industry

Lee Ott and Don Lamker

Abstract:	The use of gps differential correction has made precision agriculture possible. Precision agriculture alows us to collect better and more detailed information about a crop field and alows us to work in a closer partnership with our farmer/customers to help lead to more economical management decisions. It has ment a move from a more commodity driven to a more service oriented approach to the crop input business. There are three Network Control Centers (NCC) that comprise the world wide OmniSTAR Virtual Base Station System. These centers are located in Perth, Australia, Oslo, Norway, and Houston Texas. The Perth NCC uplinks data from Asia, Australia, New Zealand over two satellites. The Oslo NCC uplinks data from Europe, Middle East and South Africa over two satellites. The Houston NCC uplinks data from North and South America over three satellites. A coverage diagram of the OmniSTAR system is shown in Figure 1. The shaded areas of the map represent where there is coverage into an omni directional antenna receiver system.
