GPS in Education
Transcript of GPS in Education
we'll NEVER be lost! Oooops ..."
~ Russell, UP (Disney-Pixar, 2009) What is GPS? How does GPS work? How can I use GPS? What is a GPS chip? How do I find my
way using GPS? How accurate is GPS? Did you know? Where can I learn more? GPS can be used to find
your way to wherever you
need to go. A geocache is a box that
contains treats or prizes.
Take one ... leave one. A letterbox is like a
geocache. Instead of prizes,
exchange stamp imprints. Benchmarks are placed by
the National Geodetic
Survey. A Degree Confluence occurs
where a line of latitude crosses
a line of latitude. A GPS zeroes
out on a Degree Confluence. GPS chips are embedded in
technology ... including
laptops, tablets, phones,
cameras, watches, game
systems, cars, and much more. GPS chips can be in shoes,
dog collars and injected
into animals or humans.
They can even be used to
track fetal movement. Use GPS for scientific
eBird, drinking water
assessment, etc. Use GPS for games and for
scavenger hunts: TravelBug,
Flat Stanley, Shutter Spot,
Minute War, Geodashing, etc. GPS in Education The Russian satellite Sputnik launched in 1957 triggered the idea of gps technology. The first GPS
1978. It takes 65 - 85 milliseconds for a signal from a GPS satellite to reach earth. Before 1983, the GPS was only available to the military. The accuracy of a GPS depends on:
(a) the receiver
(b) satellite signals received
(c) atmospheric conditions
(d) signal blockage
(e) other factors (time of day, weather, gps model, etc.) Before GPS, ships and planes navigated the oceans and skies using the stars. GPS is used in agriculture for
precision farming. It's also used
for creating corn mazes and in construction. GPS can be several meters off hotizontally and tens of meters off vertically. Rockingham County GPS - http://www.rockingham.k12.va.us/HowTo/GPS/gps.htm

Check distance. When you turn on your gps receiver, make sure you connect to at least three satellites before you attempt to use it. This is called "triangulation" or "trilateration." Lynne Pike
