Lamp, Rynearson & Associates, Inc. of Omaha is pleased to announce the recent availability of the Metro Area Reference Network (MARN). MARN is the first Global Positioning System (GPS) Network in eastern Nebraska with Real-time Kinematic (RTK). RTK satellite navigation is a technique used in land surveying based on the use of measurement signals, where a reference station provides real-time corrections within a centimeter level of accuracy. GPS base stations located throughout Douglas, Sarpy, Saunders, Lancaster, Washington, and Pottawatamie counties make it possible to obtain survey accuracies without the need of a site base station, saving time and increasing efficiency in the field. MARN’s Eastern Nebraska subscription coverage provides GPS users time-effective setup and accuracy. For more information on MARN, please contact Todd Whitfield, MARN representative, at (402)496-2498.
