How To Get The Best Gas Mileage From Your Car By Using GPS

Categories: GPS Articles | February 23rd, 2009 | by Mike Tucker | no comments

Everybody is asking how to get the best gas mileage from their cars these days; well some of us already have one simple way to achieve this. Many of us have now got a GPS (Global Positioning System) in our cars. This little device which is mounted onto the dashboard helps us to find our way around unfamiliar cities by telling us where and when to make a right or left turn, or by finding the best route to a certain location. But how many of us are using our GPS to get the best gas mileage from our cars?

One way to use our GPS to get gas mileage improvements is to ask it to find the quickest route to out destination. Notice that I said quickest and not shortest route, that’s because the route on a map that looks the shortest may in fact be filled with stop signs and other hold ups that would be wasting precious gas. So it’s much more economical to ask it to find the QUICKEST route.

Another plus of using a GPS is that most of them will let you mark hundreds of your favourite locations, and places that you visit on a regular basis. These location marks (“waypoints” if you want the correct term) will help your GPS to map out the quickest route for your multiple stops, so saving you gas by not having to run around all over the place.

The GPS has come along way since it first came out, and the newer versions are even better. The next generation in GPS utility has begun with Dash, a device that incorporates aspects of social networking. These aspects allow it to tell you much more than just where to make the next turn or where you are at any particular time. It can also tell you where the traffic hold-ups are.

With the use of an internet connection along with a two-way satellite connection it allows the user to send information as well as receive it. This system makes the traffic reports generated by Dash very detailed and up to date minute by minute. This is because while you are driving Dash is constantly transmitting anonymous information on your speed and location. You can also use Dash’s internet connection to access social networking sites, allowing YOU to post information on traffic hold-ups so helping other drivers following or using the same route as you.

So Dash is constantly calculating your route by using maps and real-time traffic information. This highly personalized; detailed and immediately updated information on traffic reports makes it a really effective way to get gas mileage improvements as well as saving you valuable time stuck in traffic.

Another bonus of using Dash is that it can tell you where to get the cheapest gas available on your route by using its internet access to sites like Gasbuddy. So if you are still trying to find out how to get the best gas mileage from your car, the proper use of a good GPS with something like Dash is a great start.

What is GPS Used For Today and How Does a GPS Receiver Work?

Categories: GPS Articles | February 21st, 2009 | by Mike Tucker | no comments

When you hear about General Positioning System (GPS) system, you should first consider the GPS receiver. It is the part of the device responsible of processing the signal sent by the satellite in the space to find out your actual location. The receiver is usually placed on the dashboard of your car or underneath it. It renders on a dedicated output device your screen your destination.

The entire GPS is a constellation of about 27 satellites rolling around the center of the Earth at a steady speed. Amongst these satellites, 24 of them are responsible of processing signals emitted by the receiver and the remaining satellites are used for storage purposes on case of an unplanned event. The GPS receiver is responsible of hooking up with satellites used for storage purposes and working out its position from that satellite by computing their distance. The mathematical tenet used for this purpose is named trilateration.

Trilateration can be achieved in two dimensions and also in three dimensions. The rationale of this mathematical principle is to work out a triangle where you are located at the center of it. As soon as the GPS receiver emits its position and makes a connection with other satellites, it immediately works out three nearest points and computes your position.

Three types of GPS receivers can be noticed: those which can be installed in a car, lightweight and mobile GPS receivers and tracking GPS receivers. It is obvious that portable receivers are a huge boon for outdoor activities.

Finally, it is good to know that the actual process of GPS receivers is a little bit more intricate than what was described in previous sections. However, throughout this article, although the main objective was to give a broad overview how they work in theory the next paragraph will delve into advanced details about GPS computations.

From previous sections, we learnt that the GPS receiver computes its distance to the nearest available satellites in space by noticing the time spent by the emission of a given signal from the receiver to the satellite. There are another category of GPS receivers that you have not mentioned throughout this article. In order to overcome the lack of precision of the traditional GPS receiver, differential GPS receivers were born. Their rationale is to estimate the level of GPS errors at a stationary receiver station with a location that was already computed before. Since the Differential GPS hardware at the station is already aware of its own location, it can work out its receiver's level of errors in a straightforward way. The station then broadcasts a radio signal to all Differential GPS-equipped receivers in the nearby area, providing signal correction information for that area. In general, accessing this correction information makes Differential GPS receivers much more correct and precise than traditional GPS receivers.

The most essential function of a GPS receiver is to pick up the transmissions of at least four available satellites and combine the information in those transmissions with information in an electronic almanac, all in order to figure out the receiver's position on Earth.
