Satellite navigational systems, or sat navs, have changed the way we navigate our way around the high roads. Gone are the days when travellers had to have a glove box full of maps and gone too is the need to stop and ask a local for directions.

Satellite navigation means that we an now go from point A to point B confident our systems will take us there and while sat nav systems are not fool proof (we must have all read the stories of people driving over cliffs and into rivers etc), it has certainly revolutionised our wayfinding.

Currently there is only one Global Navigational Satellite System (GNSS) the American run Global Positioning System (GPS). Although, a rival European System (Galileo) is set to go online sometime after 2012 and a both a Russian (GLONASS) and Chinese (COMPASS) system are being developed.

However, all these GNSS networks will operate using the same technology as employed by GPS, and in fact, current GPS systems should be able to utilise these future systems without much alteration.

The Car GPS system is basically a constellation of satellites (currently there are 27). These satellites each contain onboard an atomic clock (actually two are on most GPS satellites but for the purpose of this explanation only one need be considered). The signals that are transmitted from the GPS satellite contain several pieces of information sent as one integer:

* The time the message was sent

* The orbital position of the satellite (known as the ephemeris)

* The general system health and orbits of the other GPS satellites (known as the almanac)

A satellite navigation receiver, the kind found on the dashbopard of your car, receives this information and using the timing information works out the exact distance from the receiver to the satellite. By using three or more of these signals the exact position can be triangulated (four signals are actually required as height above sea level has to be worked out too).

Because the triangulation works out when the time signal was sent and how long it took to arrive at the receiver, the signals have to be incredibly accurate. Even a second of inaccuracy could see the navigational information out but thousands of kilometres as light, and therefore radio signals, can travel nearly 300,000 km each second.

Currently the GPS satellite network can provide navigational accuracy to within 5 metres which goes to show just how accurate atomic clocks can be.

If you drive a lot and are looking for an alternative to your standard stereo system, an in-dash car DVD player may be a great solution for you. There is no harm in adding another source of entertainment while traveling, and an in-dash DVD player is certainly something to consider.

If you have children you want to entertain, you may want to look at other options as in-dash DVD players are not intended for use while driving. The players do have other features, however, that can be used while driving. Most in-dash players require replacing the existing stereo system, so they will also read CDs and MP3 discs. One important thing to consider though, is that these players do not usually have AM/FM radio included but rather provide satellite radio. So broadcast radio is not an option.

There are basically two types of in-dash DVD player . One is the factory installed model that comes brand new with the car. Usually considered premium accessories, these are often installed in a car instead of a stereo system. The other type is the after-market installed player. These are installed after the car's purchase and usually include the removal of the car's original stereo system. It is important to consider this option as installation is usually considered an alteration of the vehicles electrical system and could possibly void the car's warranty.

When considering an in-dash car DVD player, there are also benefits. For older cars that have no CD, MP3 or iPOD options, in-dash players can provide a cost-effective solution. The DVD player is nice for those who have to drive long distances by offering a welcome break when stopping to rest.

If you have weighed all the options and choose this type of car DVD player, cost will be an important factor in which one you end up buying. There are a wide variety of players to choose from with costs ranging from under $100.00 to $400.00 or more. The choice comes down to what features you want as well as what brand you want. Name brands like JVC cost more than lesser known brands. It depends on what you're looking for.

If you decide you want to upgrade to a DVD system in your car, and you consider the varieties of players available, the in-dash car DVD player could be the solution you want at a price you can afford.

A car DVD player can provide hours of entertainment for those long family trips and an in-dash car DVD player is an excellent choice for the audio-video enthusiast in you.

A dual screen car dvd player is the answer for those long trips in the car for quality entertainment and a place to plug in your home video game system on the road. The average price range for these units starts in the range of $150.00 to well over $400.00 depending on the type of screen, size and brand that you choose to install. It is important to remember that when choosing a system to include the cost of professional installation if you are not doing the work yourself. There is also another option where the unit comes in a bag with the dvd player and screen that is very portable. This unit can be sat on the child's lap or can be centrally located if more than one person wants to watch. The benefit of these is that they help you avoid the cost of installation with labor and time, and can be used in more than one vehicle.

Using a dual screen dvd player on vacation helps children to entertain themselves in the car by watching a favorite movie or playing a video game. There is the option to have the children wear headphones that attach to the unit so that volume is not heard by passengers who don't want to watch. One word of caution for these is to be careful with the volume level - if too loud, it can be distracting to the driver, and it should not be overly loud in the child's headphones as it can cause hearing damage. Talk with your children about the appropriate level of volume, their proper use and safety tips regarding the driver.

For a driver to have optimum safe conditions, make sure that the unit is not distracting to you in any way, which makes the before mentioned headphone(s) option very wise. If you plan to do your own installation, follow manufacturer's directions and use the proper tools. If you do use the smaller screen and player in a bag, you can buy a power converter that plugs directly into your console that can have the power cord inserted into it. This allows you to run the unit off the car's battery instead of off a charged battery that has a limited time period. Make sure that you purchase the correct voltage for both your unit and car for safety considerations.

A dual screen dvd player is a great investment if you do a lot of on the road traveling. Consider your overall costs before choosing a unit, discuss safety considerations with your children, and you will enjoy the benefits that this entertainment package offers.
