2. • To enhance understanding about GPS
Background
How it work
Application
• To evaluate its potential benefit & harm
• To analysis people’s view on GPS
(Survey result )
9. Transmit information
- Time
- Location
Satellite circle the earth
Triangulation
Receivers use -Identify
triangulation to positions by
calculate the user's
distance and
exact location. angle
10.
GPS: Very small clock error, results in a large position
error
◦ Receivers use four or more satellites to solve for x, y, z, and t
11.
12. Space Segment

equation
20. Efficient &Effective
Provide highly accurate
location
Provide clear direction &
distance of destination
High Availability
- Be used at anytime
Enhance public safety
No cost involved
Poor reception in some
areas
Interfere one’s privacy
21. • Objectives:
- More resources should be put in GPS development &
promotion
Bring much convenience & advantages to users in
different sectors
Can be used in different sectors
