What is a GPS How Do You Use It And What Do You Do With It?
A GPS is a … Electronic instrument to determine a location based on information it receives from satellites Stands for Global Positioning System Is the electronic replacement for compasses in determining location Is the electronic replacement for astronomy in determining location
The Recreational GPS When powered on will take several minutes to lock onto satellites. These satellites are 11,000 miles in orbit Used to find Longitude and Latitude To map data To make maps To find the car To find a prize But for a variety of reasons
Longitude and Latitude http://www.hammondmap.com/sites/hammond/geography/latlong1.html
What To Do In Math??? Find distances with or without Excel Find areas Do conversions to switch back and forth between the 3 formats http://www.math.uncc.edu/~droyster/talks/NCTM_2003/NCTM_Handout.pdf http://www.math.uncc.edu/~droyster/ http://www.ppi-far.org/ppiweb/ppibase.nsf/$webindex/article=2188CA5885256965005ECE28994F9E43
What To Do History??? Discuss Columbus use of the Tradewinds Research instruments used for locating positions before GPS Trace the route of the Pony Express Trace Lewis and Clarks exploration http://www.lewis-clark.org/ http://www.americanwest.com/trails/pages/ponyexp1.htm
Trade Winds http://www.ucalgary.ca/applied_history/tutor/eurvoya/index.swf 5400 miles, in 36 days, in 1492
What To Do Geography Graph countries on an X,Y coordinate Calculate distances between countries, cities, etc. Map cell phone coverage in a small town.
Conversions 1035.75 miles between latitude lines 69.05 miles between 1 degree of latitude 1.15 miles between minutes.019 miles between seconds; which equals100 feet and 3.5 inches.
However its a Sliding Scale At 38 degrees North latitude one degree of latitude equals approximately 364,000 ft (69 miles), one minute equals 6068 ft (1.15 miles), one-second equals 101 ft. one-degree of longitude equals 288,200 ft (54.6 miles), one minute equals 4800 ft (0.91 mile), and one second equals 80 ft.
I Need You To Cosign Cosine Open the calculator in Windows (Start Programs Accessories Calculator) Click on View & Scientific Choose Decimal and Degrees Type in known latitude in the following format 11735 as opposed to 33 11.735) degrees. degrees (33.11735 as opposed to 33 11.735) Click the Cosine Key (cos) Multiply answer by 69 The answer is the miles between longitudes at that latitude
