1. 1. What is the primary idea of the content in the articles?
This article writes about car navigation system.The car
navigation system displays a position with GPS. It typically
uses a GPS navigation system to acquire position data to
locate the user on a road in the unit's map database. Using
the road database, the unit can give directions to other
locations along roads also in its database. Dead rocking
using distance data from sensors attached to the direction, a
gyroscope and an accelerometer multipath can occur due to
urban canyons or tunnels.
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.
Because a paragraph sticks to an article, I think that I am
easy to read.

2. In addition, it is easy to understand because I specify a
procedure finely. The road database is a vector map of
some area of interest. Street names or numbers and house
numbers are encoded as geographic coordinates so that the
user can find some desired destination by street address.
Points of interest will also be stored with their geographic
coordinates. Point of interest specialties include speed
cameras, fuel stations and public parking.
3. What details are included in the articles?
A detailed procedure when I really use car navigation
system is written for this article. This article writes how car
navigation system acts. Contents can be produced by the
user base as their cars drive along existing streets and
communicating via the internet, yielding a free and
up-to-date map. The original system uses CD-ROM-based
maps, with ISO Level 1 encoding for their file system. Map

3. media can be recognized by the presence of the following
files on the CD.
4. Was there anything that was confusing? If so, what is it?
Because prose was long, there was the article that it was
hard to read. In addition, I may not understand the detailed
information because I write only minimum information. But I
think that it is an article useful very much when I use car
navigation system for the first time. The receiver can
calculate its total distance from each satellite. It then uses
this information to calculate exactly where it is located. I
think that I become the article that I am easy to understand
more if I use more images and pictures.
5. What is good about the writing? Why is it good?
Because this article keeps a paragraph and writes it, I am

4. plain. In addition, it is readable immediately because I write
only minimum information. The Physical Storage Format
initiative is an industry grouping of car manufacturers,
navigation system suppliers and map data suppliers whose
objective is the standardization of the data format used in
car navigation systems, as well as allow a map update
capability. Standardization would improve interoperability,
specifically by allowing the same navigation maps to be
used in navigation systems from different manufacturers.
6. Are there any errors that need to be corrected?
Because a procedure is specified finely, it is easy to
understand the article adding a paragraph to. However, I
think the detailed information not to write it. In addition, it
may be hard to understand because I do not use the image.
The road database may be stored in solid state read-only
memory, optical media, solid state flash memory, magnetic

5. media, or a combination. A common scheme is to have a
base map permanently stored in ROM that can be
augmented with detailed information for a region the user is
interested in.
7. What specific suggestions for improving the articles can
you make?
I make it easy I use an image for an article, and to
understand it. With real data as a list, I keep reliability for an
article. Some navigation device makers provide free map
updates for their customers. These updates are often
obtained from the vendor's website, which is accessed by
connecting the navigation device to a PC. Some newer
systems can not only give precise driving directions, they
can also receive and display information on traffic
congestion and suggest alternate routes.

6. 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).
 If is the group of us; an image and a picture of the
article, in addition, make it easy to understand it.
 We make it a plain article with a paragraph.
 We carry real data and keep reliability for an article.
9. Study the following video carefully and then summarize
10 major points that you were able to understand.
 With a function of the GPS; and a method in search of
a mobile telephone.
 It can use the inside hardware of the telephone for a
GPS place and am considered to be it.
 Your service provider reports your place with GPS.
 You can find the telephone and can look where there is
it.

7.  For the iPhone there is a piece of technology called
MobileMe.
 It can chase it where there is your iPhone.
 There is a GPS function in iPhone.
 Without a battery of the carrying, we can use the GPS
function.
 Money is necessary every month to use the GPS
service.
 iPhone can confirm whether data were stolen.
10. Study the following video carefully and then summarize
10 major points that you were able to understand.
 iPhone can know a current place.
 Your current location on an iPhone is found by tapping
on the Maps icon.
 A local map is displayed when we push the aim icon.
 iPhone can display a position on a map now.

8.  We enlarge a map freely, and it can reduce.
 Now to find out where you are currently you want to hit
this little button right here.
 It can see a massive thing to get you down relatively
close.
 if you hit it again just perk it up and you can see if it can
get in there or you can just take it and start to zoom in a
little bit closer.
 the more information it gets over time you will see that
in a moment.
 It is probably within a quarter of a mile of where we are
now.
