<p> NREM 446/546 Week 1, 2012 Reading assignment: GPS: A guide to the next Utility pp. 2-37, GIS Fundamentals: pp. 1-20 (Ch. 1), and Explore http://www.spaceandtech.com/spacedata/constellations/navstar-gps_consum.shtml http://www.spaceandtech.com/spacedata/constellations/glonass_consum.shtml</p><p>Material covered in this week contributes to the accomplishment of the following course goals: Goal 1: Demonstrate a basic understanding of the theory behind GPS and the reasons for its use</p><p>Information obtained from this week will help you understand basic principles associated with the theory and use of GPS and will lay the groundwork for data collection using a handheld GPS unit.</p><p>After studying class notes and reading assignments, participating in class discussions, and conducting lab. 1, you should be able to:</p><p> Discuss the developmental history of GPS in the United States</p><p> Demonstrate how the combination of time, speed of light, and known accurate locations of transmitting stations (GPS satellites) can be used to determine the position of a receiving station.</p><p> Describe the three segments of the NAVSTAR system.</p><p> Explain the following terms:  Ephemeris  Almanac</p><p> List and describe the three possible methods of positioning using GPS</p><p> Demonstrate the necessary initial setup of a Trimble GeoExplorerXT in preparation for field data collection.</p><p> Use a GeoXT to determine your current position</p><p> Justify the use of a GeoXT for data collection given the apparent accuracy you observe during the first lab period.</p><p> Describe the error associated with interchanging NAD83 locations with NAD27 locations and vice versa. (Note, there are 4 possibilities here) o Read NAD27 from a map for navigation with a GPS set to NAD83 o Read NAD83 from a map for navigation with a GPS set to NAD27 o Collect NAD83 locations with GPS and plot to a NAD27 map D:\Docs\2018-04- 16\0157df969a9627c5fa7ab38c068e71fd.doc o Collect NAD27 locations with GPS and plot to a NAD83 map</p><p>D:\Docs\2018-04- 16\0157df969a9627c5fa7ab38c068e71fd.doc</p>
