Klappentext
This book covers satellite position location technology and how the GPS system has evolved. You will learn the functional parts of GPS systems, how they work together to provide position measurements that are accurate to within centimeters.n n nThe operation of GPS is described including satellite acquisition, signal reception, and pseudo-ranging. Discover how time reference and error correction data is used and why it is very important to provide precise satellite positioning. Global Positioning System is a navigation system that uses satellites to act as reference points for the calculation of position location. You will learn how GPS devices can use other systems or devices to provide location services when there is a temporary loss of a satellite links.n n nExplained are the multiple types of civilian and military codes used in the GPS system and how they provide different levels of accuracy and reliability. GPS radio technology is described including the frequencies GPS uses, modulation and power levels.n n nYou will learn about the many applications that use GPS technology including mapping, location monitoring, agriculture control, navigation, navigation warfare (NAVWAR), surveying and structural deformation monitoring. Learn how GPS is used in combination with other position detection systems such as laser ranging to provide 3 dimensional charts and maps.n n nThe sources of GPS errors are explained such as orbital position errors and variation in radio propagation. You will learn ways to minimize the errors. such as receiver initialization, RTK and differential GPS (D-GPS). A brief deillegalscription if the interface and data format standards is provided.n n nThis Book Provides:n n n• Deillegalscriptions of the Functional Parts of the GPS Systemnn • How the GPS System Worksnn • Key GPS Applicationsnn • GPS Signal Availability and Receptionnn • GPS Radio Technologynn • GPS Codes, their Accuracy and Usesnn • GPS Data Formatsnn • Sources of GPS errors and ways to Correct it.nn • Real Time Kinematic (RTK) GPSnn • Differential GPSnn • Terrestrial Based Positioning Systemsn n n• Upcoming Changes to the GPS System
