Global Positioning System Ppt Finale Pptx More commonly used in the 21st century gps is for navigation, syncing computer networks time, missile guidance some applications that make use of gps are garmin’s, google maps, mobile apps gps satellites are maintained by the air force and can be used by anybody global positioning system (gps): how it works at least 24 operational gps. تُستخدم تقنيات gps في مجالات متعددة مثل الملاحة، الزراعة، والخرائط، مما يساهم في تحسين الكفاءة وتقليل المخاطر. download as a ppt, pdf or view online for free. Where am i going and how do i get there? early solutions: • marking trails with piles of stones (problems when snow falls…or on ocean) • navigating by stars (requires clear nights and careful measurements) most widely used for centuries …location within a mile or so modern ideas: • loran: radio based; good for coastal waters …limited outside of coastal areas • sat nav: low orbit satellites; use low frequency doppler …problems with small movements of receivers department of defense finally said: “we need something better: all day and all night; all terrain” end product is global positioning system (gps) • system (constellation) of 24 satellites in high altitude orbits (cost ~ $12 billion) • coded satellite signals that can be processed in a gps receiver to compute position, velocity, and time • parts of system include: space (gps satellite vehciles, or svs) control (tracking stations) users first one launched in 1978 ….june 26, 1993 air force launched 24th sv orbit ~ 12 hours 27 satellites: 24 operational and 3 spare ground tracks basic concept is that the gps constellation replaces “stars” and gives us reference points for navigation examples of some applications (users): • navigation (very important for ocean travel) • zero visibility landing for aircraft • collision avoidance • surveying • precision agriculture • delivery vehicles • emergency vehicles • electronic maps • earth sciences (volcano monitoring; seismic hazard) • tropospheric water vapor anything that involves location, motion, or navigation examples of applications we will break system into five conceptual pieces step 1: using satellite ranging step 2: measuring distance from satellite step 3: getting perfect timing step 4: knowing where a satellite is in space step 5: identifying errors gps block i gps block ii gsp satellite vehicles (svs): two generations: block i and block ii weigh ~1900 lbs. built by rockwell step 1: using satellite ranging gps is based on satellite ranging, i.e. distance from satellites …satellites are precise reference points …we determine our distance from them we will assume for now that we know exactly where satellite is and how far away from it we are… if we are lost and we know that we are 11,000 miles from satellite a… we are somewhere on a sphere whose middle is satellite a and diameter is 11,000 miles if we also know that we are 12,000 miles from satellite b …we can narrow down where we must be… only place in universe is on circle where two spheres intersect if we also know that we are 13,000 miles from satellite c …our situation improves immensely… only place in universe is at either of two points where three spheres intersect three can be enough to determine position….
