did you know that GPS is important to everything in our lives.
- 00:06 - 00:08
The question I want you to ask yourself is
- 00:08 - 00:09
what is GPS
- 00:10 - 00:13
Most of you will say. It's just something we used to get from point A to point B.
- 00:14 - 00:18
Today I'm going to tell you a little bit more about GPS application in Dept
- 00:22 - 00:25
GPS stands for global positioning systems
- 00:25 - 00:30
which is a navigation system using satellites. A receiver
- 00:30 - 00:35
an algorithm to synchronize location, velocity and time data for air,
- 00:35 - 00:37
sea and land level.
- 00:38 - 00:38
Mhm.
- 00:39 - 00:41
There are three parts of GPS
- 00:42 - 00:45
satellites, receivers and software
- 00:46 - 00:48
satellites are you for?
- 00:49 - 00:51
It were a ride range of purposes,
- 00:52 - 00:55
cell phones, tv military purposes and many more.
- 00:56 - 01:01
It is also used with gPS E G P s satellites transmit data
- 01:01 - 01:04
indicates its location in the current time.
- 01:04 - 01:06
All GPS satellites synchronized
- 01:07 - 01:09
operations so that these repeating signals
- 01:10 - 01:11
are transmitted
- 01:11 - 01:12
at the same instinct.
- 01:14 - 01:18
The GPS receiver compares the time a signal was transmitted
- 01:18 - 01:21
by a satellite with the time it was received.
- 01:21 - 01:26
The time difference tells GPS receiver how far was the signal is?
- 01:30 - 01:32
Now we're going to talk about calculating distance.
- 01:36 - 01:40
So you would do velocity times time, which will equal your distance.
- 01:42 - 01:46
Radio waves travel at the speed of lightly
- 01:47 - 01:49
186,000 mph.
- 01:51 - 01:54
If you took 0.08 seconds to receive the
- 01:54 - 01:58
signal transmitted by satellite floating directly overhead.
- 01:59 - 02:02
Use this formula to find your distance from the satellite.
- 02:03 - 02:03
So
- 02:06 - 02:15
if I had 0.8 seconds, I will do the math as 186,000 miles per second times 0.8 seconds,
- 02:16 - 02:19
Which will equal 14,880 now.
- 02:21 - 02:23
Trial adoration.
- 02:23 - 02:27
Trial operation works by having at least three points in a stage.
- 02:28 - 02:31
In each point releasing a circular signal.
- 02:31 - 02:34
The point where the signals are the lap is the GPS.
- 02:34 - 02:39
Although there is a degree of error, this can be reduced by having more satellites,
- 02:40 - 02:41
Usually three or 4.
- 02:44 - 02:46
Now we're going to talk about something
- 02:46 - 02:49
good things and some bad things about GPS.
- 02:50 - 02:52
Some advantages of GPS
- 02:52 - 02:54
are very high speed,
- 02:54 - 02:56
easy to navigate.
- 02:56 - 02:57
Very low cost
- 02:58 - 02:59
military usage,
- 03:00 - 03:02
security and crime checker,
- 03:02 - 03:05
traffic and weather alerts available anywhere.
- 03:06 - 03:10
Some disadvantages are driving distractions,
- 03:10 - 03:11
signal failure
- 03:12 - 03:13
in accuracy
- 03:14 - 03:16
in commercial explode,
- 03:17 - 03:18
tissue
- 03:18 - 03:19
exploitation.
