Why GPS is important Why GPS is important for MIS studentsfor MIS students

GPS is the root technology for GIS applications GPS is operationalized via satellite constellations,

geostationary and low orbit satellites m-commerce rests on GPS GIS is important new business application Encourage further study with ArcView or GIS

classes in Geology or elsewhere

How does GPS work in How does GPS work in generalgeneral

Constellations of at least 24 satellites operated by DOD

Removed selective availablity GPS satellites radio down data packet every 30

seconds, with pseudo random bit pattern Calculates signal delay differences Uses how long signal took to get to receiver,

satellite’s velocity, and time of transmission and triangulates three signals or more to pinpoint spot

Fairly reliable unless under canopy or in unusual regions

Why is GPS so interestingWhy is GPS so interesting For a long time, man only knew latitude based on the stars,

and ships were lost and wrecked Progress was made with determining longitude when clocks

helped to establish locations based on celestial relative to the earth at certain times (required expert seamanship, accurate charts, sextants)

Polar magnetic fields shift daily Now, can get 3 meter accuracy Get latitude, longitude and altitude with high degree of

accuracy and little amount of skill Predict will radically change the world that we live in

technologically

Sample Applications of GPSSample Applications of GPS Alzheimer’s patients Lost dogs World Trade Center mapping Smart bombs Car nav systems Fishing, hunting and camping Child tracking Prisoner tracking and monitoring Golf game enhancement Criminal activity pattern mapping

Sample Applications in Sample Applications in BusinessBusiness

Tool for sales and marketing with GM, Ford with OnStar type products

GIS applications in mining, property management, cable mapping, maintenance

GIS decisionmaking tools using algorithms FedEx, UPS and trucker tracking Know where all inventory and equipment are

located m-commerce
