Another benefit of the navigational systems is that most insurance companies these days are actually willing to lower your monthly car insurance bill as long as you have one of these systems installed in your vehicle. Whether your vehicle comes with it already installed or you buy one yourself and install it on your own, it doesn’t matter as long as you have one in the car, they will be willing most likely to lower your rates.

Most the vehicles that are released today come standard with a GPS system included in them which is nice, but if you have an older model car you still have the option of getting a navigational system in your vehicle, as long as you go out and purchase and install one yourself.

It is pretty easy to see all the great benefits that these systems have to offer and why you need one in your vehicle. You should stay up to date with the times and make sure that you and your family are always as safe as possible, which you will be with one of these systems.

The line of SONY Bravia has always been appealing to me, considering the fact that SONY always manufacture top-of-the-range electronics. I had in mind something in the range of 42 to 50 inches. I love watching my NBA games, especially now during the Finals. Nothing beats watching Kobe’s prowess in high-definition. Trust me, once you switch to HD programming you won’t look back.

I now get my HD programming from Dish Net Work. They have some of the best options. Take, for example, their TurboHD package. They have TurboHD Bronze, Silver, and Gold. Their most basic only starts at $9.99 a month but if you order Classic Bronze 100 (formerly known as America’s Top 100) you get TurboHD Bronze free for 6 months.

Anyways, back to my SONY Bravia. I finally settled for a magnificent 46-inch plasma screen. The technicians over at Fry’s installed it in my living room in no time. The following day I got Dish Network set up. I spent a good 20 minutes on the Dish programming page on their site choosing which package to go with. Seeing that I was now the proud owner of a 46-inch plasma it only made sense for me to complement it with some HD programming.

I therefore chose Dish Network’s “Everything” Pak (which has over 250 channels) How much for all of this ? $72.98 per month. Now that’s a great deal, if you ask me, or anybody for that matter. I also get movies and NBA TV, which allows me to follow my games. Too bad my wife isn’t an ardent follower of basketball. She prefers watching the Oxygen Channel, something I never watch !

SONY have really outdone themselves when it comes to making these high-end television sets that have changed the way we watch TV. Pop in a DVD and the image literally jumps out of the screen ! The highlights of my day is when I connect my BluRay-enabled Sony VAIO (yes, I love SONY products) to the TV and watch a movie. The picture quality is out of this world. You have to see it to believe it.

Bundle a plasma or LCD with the digital picture you get from Dish Network I guarantee you will be stuck on your couch. It’s a mind-blowing experience.

classes of radio that allow transmission ranges of
up to 100 meters by boosting the radio power. The
technology of Bluetooth isn’t limited to line of
sight transmission since it uses directional waves
that are capable of transmitting through many
obstructions.

Bluetooth is an industry standard communication of
wireless, meaning that it enables the connection
of other devices as well, such as cell phones,
computers, digital cameras, and other types of
electronic devices. The specification of Bluetooth
defines a radio system and a “stack” of protocol
layers and profiles. The highest layer is the
application layer, while the lowest layer is the
radio.

The wireless technology of Bluetooth is positioned
to revolutionize the personal connectivity market
by providing freedom from inconvenient fixed type
lines.

The specification for Bluetooth eliminates the need
for cables by providing a small form factor, low
cost wireless solution that will link computers,
cell phones, and other electronics. Bluetooth
also allows users to connect many ranges of devices
quickly and easily and expands communications
capabilities as well.

The size of the Bluetooth radio is amazing, as a
Bluetooth radio can be built into one or two very
small microchips then integrated into any electronic
device where wireless operations would be an
advantage.

Bluetooth also offers a robust link, which ensures
that normal operating circumstances are not
interrupted by interference from other signals
that are operating in the same frequency band.

Also known for its worldwide operation, Bluetooth
radio operates in the 2.4 GHz frequency band, which
is license free and available to any type of
radio system in the world. No matter where you
are in the world, you count on Bluetooth to work.

Security is also important. Offering advanced
security mechanisms, Bluetooth ensures a high level
of security. Therefore, authentification will
prevent unauthorized acess to important data and
make it very difficult to listen in.

Bluetooth also boasts power optimization. The radio
is power friendly and the software for Bluetooth
is very configurable, limiting the power consumption
of equipment. The radio itself only consumes a
small amount of power from a cellular phone.

In order to determine if some of these commercially available units are for you, it’s likely wise to understand a little of the history & workings of present GPS systems.

Global Positioning System satellites transmit signals to equipment on the ground. GPS receivers passively receive satellite signals; they do not transmit. GPS receivers require an unobstructed view of the sky, so they are used only outdoors and they often do not perform well within forested areas or near tall buildings. GPS operations work on a on a very accurate time reference, which is provided by atomic clocks at the U.S. Naval Observatory. Each GPS satellite has atomic clocks on board.

Each GPS satellite transmits data that indicates its location and the current time. All GPS satellites synchronize operations so that these repeating signals are transmitted at the same instant. The signals, moving at the speed of light, arrive at a GPS receiver at just slightly different times because some satellites are farther away than others. The distance to the GPS satellites can be determined by estimating the amount of time it takes for their signals to reach the receiver. When the receiver estimates the distance to at least four GPS satellites, it can calculate its position in three dimensions.

There are at least 24 operational GPS satellites at all times. The satellites, operated by the U.S. Air Force, orbit with a period of 12 hours. Ground stations are used to precisely track each satellite’s orbit.

Determining Position

A GPS receiver “knows” the location of the satellites, because that information is included in satellite transmissions. By estimating how far away a satellite is, the receiver also “knows” it is located somewhere on the surface of an imaginary sphere centered at the satellite. It then determines the sizes of several spheres, one for each satellite. The receiver is located where these spheres intersect.

GPS Accuracy
The accuracy of a position determined with GPS depends on the quality of receiver. Most hand-held GPS units have about 10-20 meter accuracy. Other types of receivers use a method called Differential GPS (DGPS) to obtain much higher accuracy. DGPS requires an additional receiver fixed at a well known location nearby. Observations made by the stationary receiver are used to correct positions recorded by the roving units, producing an accuracy greater than 1 meter.

When the system was created, timing errors were inserted into GPS transmissions to limit the accuracy of non-military GPS receivers to about 100 meters. This part of GPS operations, called Selective Availability, was eliminated in May 2000.
