Understand the difference between post-processing and real-time kinematic (RTK) processing of position. o - Understand what a geostationary (GEO) satellite is and how it can contribute to improving GPS accuracy, as well as the regional nature of GEO systems (e.g. WAAS) o - Understand the typical accuracy obtained with GPS used in different configurations. o - Understand the concept of precise 4me and the use of GPS in determining the precise time for applications that need accurate, coordinated timekeeping. o - Be able to contrast the concept of precise (globally unified) time with that of solar time and time determined by time zones and standard vs. daylight savings time. o
