    4. Global Positioning System (GPS) Information and History COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING

    5. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING What Is GPS? • GPS, which stands for Global Positioning System, is the only system today that permits land, sea, and airborne users to determine their three-dimensional position, velocity, and time 24 hours a day, in all weather, anywhere in the world. • It is funded by and controlled by the U.S. Department of Defense (DOD). • The system was designed for and is operated by the U.S. military, however, anyone with a GPS receiver that can access the NAVSTAR (NAVigation Satellite Timing and Ranging) System can use it worldwide.

    6. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING THREE PARTS MAKE UP THE GLOBAL POSITIONING SYSTEM… 1. Space Segment 2. Control Segment 3. User Segment……YOU!!!

    7. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING THE SPACE SEGMENT… • 29 Satellites Total • 24 Navigational Satellites • 5 Active Spares • 12 Hour Orbit for each Satellite • 11,000 Nautical Miles up • 6 Orbital Planes w/ 4 satellites each • 4 Atomic Clocks to keep the accuracy (important)

    8. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING THE CONTROL SEGMENT • The GPS control, or ground, segment consists of 5 monitor stations • located around the world that broadcast signals to the satellites. • The master ground station locates at Schriever • (Falcon) Air Force • Base in Colorado Springs, Colorado. • These Ground Stations control the accuracy • of of the satellite’s position, • by using computer models and • broadcasting corrections to each • individual satellite so the GPS • receiver (YOU) can precisely • establish the location of the satellite.

    9. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING THE USER SEGMENT • The GPS User Segment consists of the GPS receivers and • the user community. • The GPS receivers detect, decode, and process GPS satellite signals • into position, velocity, and time estimates. • 4 satellites are required to compute the 4 dimensions of • X, Y, Z (position) and Time. • GPS receivers are used for navigation, • positioning, time dissemination, • and other research.

    10. COUNTY OF LOS ANGELES FIRE DEPARTMENT FIELD OBSERVER GPS TRAINING THE USER SEGMENT

    11. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING The History of GPS… • In the late 1950's, researchers realized that the radio transmissions of a satellite in a well-defined orbit could be used to determine the position of a receiving station back on the ground. • Doppler positioning was the basis for the first satellite positioning system, known as Transit, which was put into orbit by the US military in the 1960's. It provided a positioning accuracy of about 160 meters, and was used by US Navy missile submarines.

    12. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING …more History of GPS. • As it progressed it was decided that the satellites would emit signals at precisely timed intervals, and by measuring the delay of arrival of these signals, a receiver could determine the distance of each satellite. • The first GPS satellite was launched in 1978. The first 10 satellites were developmental satellites, called Block I. From 1989 to 1993, 23 production satellites, called Block II, were launched. The launch of the 24th satellite in 1994 completed the system.

    13. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING How GPS works… • The principle behind GPS is satellite ranging- the measurement of distance (or "range") between the receiver and the satellites. • The satellites act as precise reference points by transmitting their positions and time signals to the user's receiver. The receiver determines its distance from the satellites by measuring the time delay for the signal to reach the receiver. • The measurements are collected simultaneously from four satellites and are processed to solve for the three dimensions of position, velocity and time, a technique traditionally called trilateration

    14. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING What is WAAS? (Wide Area Augmentation System) • What is WAAS? • -WAAS is a system of satellites and ground stations that provide GPS signal corrections, giving you even better position accuracy. • -How much better? Try an average of up to five times better. A WAAS-capable receiver can give you a position accuracy of better than three meters, 95 percent of the time. And you don't have to purchase additional receiving equipment or pay service fees to utilize WAAS. • The origins of WAAS • The Federal Aviation Administration (FAA) and the Department of Transportation are developing the WAAS program for use in precision flight approaches. Currently, GPS alone does not meet the FAA's navigation requirements for accuracy, integrity and availability. WAAS corrects for GPS signal errors caused by ionospheric disturbances, timing and satellite orbit errors and provides vital integrity information regarding the health of each GPS satellite. Although WAAS has not yet been approved for aviation, the system is available for civilian use, such as for boaters and recreational GPS users.

    15. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING How WAAS (Wide Area Augmentation System)works… • How it Works • WAAS consists of approximately 25 ground reference stations positioned across the United States that monitor GPS satellite data. Two master stations, located on either coast, collect data from the reference stations and create a GPS correction message. This correction accounts for GPS satellite orbit and clock drift plus signal delays caused by the atmosphere and ionosphere. The corrected differential message is then broadcast through one of two geostationary satellites, or satellites with a fixed position over the equator. The information is compatible with the basic GPS signal structure, which means any WAAS-enabled GPS receiver can read the signal. 100 meters: Accuracy of the original GPS system, which was subject to accuracy degradation under the government-imposed Selective Availability (SA) program. 15 meters: Typical GPS position accuracy without SA. 3-5 meters: Typical differential GPS (DGPS) position accuracy. < 3 meters: Typical WAAS position accuracy.

    16. COUNTY OF LOS ANGELES FIRE DEPARTMENT GARMIN GPS V TRAINING Who Benefits from WAAS? • Who benefits from WAAS? • Currently, WAAS satellite coverage is only available in North America. There are no ground reference stations in South America, so even though GPS users there can receive WAAS, the signal has not been corrected and thus would not improve the accuracy of their unit. For some users in the U.S., the position of the satellites over the equator makes it difficult to receive the signals when trees or mountains obstruct the view of the horizon. WAAS signal reception is ideal for open land and marine applications. WAAS provides extended coverage both inland and offshore compared to the land-based DGPS (differential GPS) system. Another benefit of WAAS is that it does not require additional receiving equipment while DGPS does. • Other governments are developing similar satellite-based differential systems. In Asia, it's the Japanese Multi-Functional Satellite Augmentation System (MSAS), while Europe has the Euro Geostationary Navigation Overlay Service (EGNOS). Eventually, GPS users around the world will have access to precise position data using these and other compatible systems.
