1. 1. What is the primary idea of the content in the articles?
It is the car navigation capabilities depend on a global positioning system, known as GPS, which uses a network of satellites with
radio transmitters. And the car navigation system also features a sophisticated built-in map, which knows precisely where streets
are located on the surface of the earth. When you enter the address of your desired destination the map plots a course along the
streets to that location. Therefore we can easily use the car navigation system.
2. Do you think the individual sections and headings in the document (articles) clearly represent the idea that was communicated.
Explain the reasons behind your comments.
Car Navigation Basics is explain the basic function of the car navigation system. For a car navigation system to work, there have
to be at least four GPS satellites near enough for it to pick up a signal.
GPS Satellites is explain about the GPS satellites. The atomic clocks synchronize the satellites to almost exactly the same
instant, which the satellites use to send out signals simultaneously.
Calculating Location is position information is calculated to specify the location of the car. The same distance from each satellite,
its GPS gets signals from nearer ones slightly before more distant ones.
Planning a Trip guide you to the destination. If you get off course, the GPS system knows and plots a new course.

2. 3. What details are included in the articles?
The manner of the setting of the GPS function. How to turn on the power. Way of setting of a clock.
The route where you go to the destination is set. And higher route setting can be done. Using the Up and Down keys on the
remote control, select how you want the system to find your route. When the selection is highlighted, push Enter on the remote
control. Scroll the list to find your desired destination. When it is highlighted, press Enter. A map appears, and the system
calculates a route. Its voice prompts you to proceed.
4. Was there anything that was confusing? If so, what is it?
No, they weren’t.
5. What is good about the writing? Why is it good?
I think I'd like the place where order is being followed and explained politely. About How to Use a Map-Based GPS Car Navigation
System. I think that it had better be explained according to an item. About How Do Car Navigation Systems Work? Whoever reads
by explaining in these business, it becomes easy to understand.

3. 6. Are there any errors that need to be corrected?
No, they aren’t.
7. What specific suggestions for improving the articles can you make?
I hope to add the article to explain further possibility of the GPS function to this article newly. I hope to add the article to explain
further possibility of the GPS function to this article newly. For example in the satellite where you introduce GPS equipment and
use it for a GPS, it's introduced.
8. Identify three basic differences between how your group would author a similar document and how this author authored it (as you
see it in the link).
I do not understand it who wrote what kind of sentence because each does it with an individual. However, it is sure that I do my
best with all head.
9. Study the following video carefully and then summarize 10 major points that you were able to understand.
