GPS has several advantages: it provides 100% global coverage via 24 satellites in orbit; it allows for easy navigation by determining exact location via latitude and longitude; and it enables searching nearby areas and tracking locations. However, GPS also has disadvantages: battery life can be limited and signals can be inaccurate if obstructed by buildings or trees.

1. ADVANTAGES OF GPS

2. ADVANTAGES OF GPS
• 100% coverage
on the planet

3. ADVANTAGES OF GPS
• 24 satellites, orbit the earth twice a
day at an altitude of 10,800 miles
• At least 6 satellites above the
horizon

4. EASE OF NAVIGATION
• Determine exactly
where you are at
any given moment
• Give you the
exact latitude and
longitude

5. SEARCH NEARBY AREA
• Allow you to search the
local area for nearby
amenities

7. WEATHER INFORMATION
• Determine the
atmosphere’s water
content to improving the
accuracy of weather
forecasts

8. TRACKING

11. BATTERY LIFE

12. INACCURACY
• Obstacles like
buildings and trees
can deflect the signal
