2SEC has ability to utilize 6 Topcon CORS reference stations in our local network that is included in the TopNet Live system. The CORS station broadcasts data within a 22 mile radius regarding the reference station position that can be utilized by subscribing surveyors, engineers as well as potential agricultural users which have GPS receiver equipment. This signal is used by the equipment to determine a precise relative position for control surveys on the state plane coordinate system without the use of additional portable GPS base equipment.
