GPS Navigation: How Does It Work?
Using GPS navigation is becoming as commonplace as looking at a map. In-dash navigation systems are being installed in most new vehicles,portable GPS units are regularly used by hunters and hikers and GPS navigation can be enabled on most smartphones launch x431 v plus. But how does this technology work? How does that little receiver know where you are? It’s actually a fairly simple process;however getting the infrastructure set up was quite the task.
Like most technology,the Global Positioning System (GPS) was originally created for military use and has only recently become available to civilians. The first GPS satellite was actually launched back in 1978. Since that time,they’ve created a constellation of satellites orbiting the earth. Over 50 satellites have been launched,but only approximately 30 are active. The GPS satellites need to be replaced every 10 years or so.
Each one of these GPS satellites can orbit the globe twice a day. As they travel,they send out a low-power radio signal to the earth below. Your GPS navigation unit receives this signal and measures the time it took for the signal to get from the satellite to the receiver. The arrangement of their orbits ensures that you’ll always have a satellite ready to send a signal to your receiver.
A GPS unit needs to be in direct range of at least three satellite signals in order to correctly pinpoint your latitude launch creader crp123,longitude and your movement in that space. If you’re locked into four satellite signals then your receiver can also calculate altitude. This satellite information is then cross-referenced with the map database provided on the GPS unit.
While the satellites and GPS receiver are able to calculate your latitude,longitude,altitude and movement,it is the map database that names the roads and labels the buildings. It can be truly said that your GPS navigation unit is only as good as your map database. Two of the biggest map database providers are NAVTEQ and Tele Atlas. NAVTEQ is primarily associated with GPS units such as Garmin and Magellan,while Tele Atlas is usually associated with TomTom. There are many differing opinions about which map database provider is best,but as far as we’ve seen,it’s just a matter of personal preference.
If you want a completely accurate signal from your GPS navigation receiver,make sure that you are in an open area where you have a clear view of the sky. You won’t be able to see the satellites,but,trust us,they can see you. Since they use a low-power signal,the satellites need a clear path to your receiver. If you’re indoors or under heavy tree cover,you’re going to have a hard time getting an accurate signal. The signal can also be affected by reflection,whether you’re in the middle of some tall buildings or near a high rock face.
GPS navigation is a quick and easy way to get to where you want to go. However,most people take for granted the amount of work it has taken just to have your in-dash navigation system find the nearest gas station. Simple navigation requires multiple orbiting satellites,a long-distance radio signal,precise timing and extensive research for map databases. So give your little GPS unit a pat on the back the next time you use it,it has earned its keep.

Cars have certainly changed over time.

Electronic controlled transmission – helps monitor vehicle speed, gear position and throttle opening.

Distronic – An costly word for Mercedes’ cruise control system.

Roof control unit – is relevant to convertibles.

Expert advice said that nitrogen is an inert gas, and its low coefficient of thermal expansion, warming slowly, even if the car run on the highway, the tire becomes very hot, the inside of the nitrogen will be relatively stable, the volume will not change much. And it does not support combustion; non-flammable nature also can greatly reduce the chance of a puncture.
Secondly, the use of high-pressure air charge car tires, low tire pressure to ensure as far as possible. Expert advice said that in the summer, low tire pressure can improve ride comfort and steering stability of the cars, thereby preventing the occurrence of a puncture. In addition, he also pointed out that, if the owner is found due to the pressure caused by excessive tire overheating, and definitely not using the deflated tire to throw cold water on the way to lower the temperature, in which case it is best to stop naturally cool down, buck.
