4. SONAR Sonar – stands for SOund, NAvigation, and Ranging. SONAR analyzes sounds to determine distance and direction. Sonar – stands for SOund, NAvigation, and Ranging. SONAR analyzes sounds to determine distance and direction. 1.It was originally developed in 1906 to detect icebergs, but became more important as a military tool during World War I as ships tried to locate and avoid submarines near the ocean floor. 1.It was originally developed in 1906 to detect icebergs, but became more important as a military tool during World War I as ships tried to locate and avoid submarines near the ocean floor.

10. GPS Global Positioning System –a network of 24 satellites that orbit the earth and using atomic clocks, broadcast extremely accurate time measurements. Global Positioning System –a network of 24 satellites that orbit the earth and using atomic clocks, broadcast extremely accurate time measurements. On earth, GPS units analyze these time signals to provide information about location. On earth, GPS units analyze these time signals to provide information about location.

11. Facts about GPS Each of the 24 satellites orbit the earth twice every day. Each of the 24 satellites orbit the earth twice every day. They are traveling at approximately 7,000 miles per hour 12,000 miles above the earth. They are traveling at approximately 7,000 miles per hour 12,000 miles above the earth.
