What Is GPS Used For Today And How Does A GPS Receiver Work?

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.

Top Ten Tips For Computer Security

Have you ever wondered why there is a huge increase in online fraud? Well the main reason its happening, is that most computer users are not protecting themselves properly.
When you follow the top 10 tips for online and offline protection, you will discover were your computer system weaknesses are.

1. It is a proven fact that 75% of American PC users do not use an up to date anti-virus program, this is a program that scans the PC searching for any malicious software, when it discovers them they can either quarantine them or delete them. Some AV programs even scan sites you visit and detect any phishing sites.

2. Phishing sites are websites that have been created to look similar to a bank or payment processor such as PayPal. We have all received the emails from our bank stating our account is empty and to log in immediately, the hyperlink in the email you click on looks real, however the site you are taken to is fraudulent, they are after stealing your money! Always make sure your banks website has a padlock image on the toolbar, this shows that it is a secure site for logging in. If you have any doubts contact your bank immediately.

3. We all need a firewall to hide behind. This is a piece of software that prevents anyone hacking into our computers, either at home or at work. Once the software is set up it runs in the background. It basically blocks the ports on our computers that hackers use to gain access through the back door. Like the AV, there are plenty of free firewalls.

4. Is your computer operating system up to date? When did you last update it? Most people will answer, never. The main reason software manufacturers such as Microsoft provide updates, is to plug any security vulnerabilities in the software, this is why when they issue an update, its wise to update your system.

5. Check any public computers you use, as there are products out there called key loggers, this is an electronic device that logs all keystrokes and can be downloaded. So if you use the library for your online bank or eBay, make sure the keyboard lead connects directly into the computer, if it connects to an extra piece of cable, it could be a key logger. The person who put it there only has to download the information and they have all your details and access to your money! Always log out and do not save any passwords on a public computer - Ever!

6. Check public WiFi connections are public! Make sure it is not just another computer acting as a gateway, so you pass your details to them such a credit card and address, then they grant you access to the internet. While you are sending emails, they are using your credit card details to purchase products online!

7. Do not share games, as this is how some viruses were transferred from computer to computer. Always run your anti virus software to scan the disc first.

8. Do not let anyone one use a flash drive on your computer, as soon as someone plugs a flash drive into a computer a virus could be transferring to your computer, this may or may not be done on purpose, but the problem is still there, it will take information from your computer and can even email it from your computer, at a later date!

9. Physical protection at home and at work, this is essential for preventing your computer and the data stored on it falling into the wrong hands. The PC enclosure is a special steel box, that has been designed for protecting computers, so heating and security issues has been addresses, these units are fully welded and normally bolted to walls, (this is how banks protect their computers).

10. Physical protection on the move is essential for laptops, so Kingston Security offers the best option, this is a high grade steel cable that locks into the laptop and ties around a leg of a table, this prevents your personal information being stolen along with the laptop, in a smash and grab robbery.

Follow these simple steps and your online and offline security will be safe.

The Importance of Mobile Phones

Mobile phones or cell phones are wireless portable, short range electronic devices used for mobile voice data communication. The communication is carried over a cell sites. Mobile phones support services like messaging, e-mail, gaming, Bluetooth, infra-red to name only a few.
Way back in 1915, the American company AT&T contemplated the use of wireless phones. This idea was soon shelved as the company feared that its control on wired service would end. Cell phones in 1996 ushered in a new age of mobile telephony. Mobile sets could now be connected to the internet and wireless e-mail. A new generation of Smart phones was born. The mobile phones are designed with latest technology which has turned as pocket PC.

Mobile phones can transmit and receive from a number of cell sites or base stations which are fitted with the help of special antennas. These sites are normally built on a tower. Mobiles transmit voice and data to the nearest cell site with the help of a low powered transceiver. The mobile number will be registered with the mobile telephone exchange.

The sites have low powered transmitters (1 or 2 watts) and can relay between the mobile phones and the main switch. The switch helps to connect the call to another caller of the same wireless service provider or to the public telephone network. This dialogue that ensues is a flow of data which is digital and digitized audio.

There are several categories of mobile phones from basic phones to feature phones such as music phones, camera phones and smart phones. Technological advances have led to miniaturization and increased processing power of microchips. Even more features have been added to these mobiles. A high-end Smart phone five years ago is a standard phone today.

Mobile phones have features that go far beyond text-messaging and voice calls. They include internet browsing, music (MP3) playback, memo recording, personal organizer functions, e-mail, built-in-cameras, Push-to-Talk, infra red and Bluetooth connectivity. It is envisaged that in future, they will also be able to serve as consoles to online high quality games!

The utility values of mobile phones are increasing in their scope and variety. In 1999, the first mobile internet service i-Mode was launched. Of late, mobile telephones have been used by public activists and journalists. Mobile phones have added a new dimension to news -gathering. Many companies have begun to offer mobile career guidance services. There are tools for creating websites on mobile phones Banking and commerce are increasingly conducted on mobile phones in many parts of the world.

The sale of ring tones to mobiles phone companies brought a new dimension to the mobile phone industry. It is also called the seventh of the Mass Media with Print, recording, cinema, radio, TV and the internet preceding it. Mobile phones have made a great revolution in the recent years, with the advent of new technologies.

Law enforcement agencies use the triangulation method to trace mobile signals to the hide-outs of the most "wanted" people. In developing countries, in the last decade, mobiles have become pervasive tools of communication. Truly, mobile phones have only begun to re-define the concept of connectivity in the world.

Planning for a baby nursery is always ideal to welcome a new member of the family. Typically, baby nurseries are created and designed for babies. This is a room where your infant can rest safely and securely. Also, the baby's belongings and necessities are included in this room. Such things are cabinets, cribs, stools, high chairs, changing tables and other furniture. Added are infant's clothing, toys, layettes and other infant's supplies.

Furniture, as mentioned earlier are those that are very useful and functional for babies. These supplies are designed to ease the process of raising babies. Items such as cribs and high chairs are used to securely hold the baby. However, before buying these furniture, you should always check first their quality as well as the durability of the construction. Some of these furniture can be deceiving at first glance, but don't make a mistake of disregarding their hidden unsafe structure and malfunctions. For instance, check whether there are visible head nails or broken parts.

With regards to infant clothing and layettes, these supplies are very essential for infants to cover their sensitive soft skin. Also, these items shield them under hot or cold temperature of the weather. Clothing and layettes such as 1 piece or 2 piece suits, pajamas, socks, hats, bibs, beddings and the like should come in pure natural fabric.

Things I Did Before I Started My Online Business

Why did I start an online home-based business? Of course, I decided to do that after reading about others doing it and they not only make a lot of money from their business and gain their financial freedom, but also they achieve their time freedom. They can do whatever and whenever they want. I want to lead that kind of lifestyle that I used to dream about ( I'm sure most people do).

So I decided to change my life and felt so crazy about starting my own online home-based business that I told everyone about my intention ( to start an online home based business). However, rather than getting a 'green light' for that decision, what I received was a whole lot of negative remarks saying that 'it won't work' and 'you will be caught in a scam'. However, I remained strong and started to look for information in the internet. I checked out all the affiliate marketing sites, newsletters and forums. I looked for e-books about internet business by searching for keywords like 'proven internet business', 'automated income streams', 'internet marketing' and so on. There are so much information on different types of online business opportunities. All provide a guaranteed successful income (a six figure monthly income, mind you), and ask to join them and follow in their footsteps.

At this point, I thought that the first words were going to be true, that I will be scammed and I felt the need of a mentor or teacher who has already been there and done that, and is able to guide me to succeed. While searching the internet one day, I found a free e-book called The Dotcomology, written by the Home Biz guy. I studied that e-book and finally signed up through the pluginprofit site. After that, it was all history. Now, I have a website to promote my online opportunities. Also, the system provides full guidance to start my online home-based business.By having my own website with my own domain name and hosting account, my website looks professional and gives a good impression to my subscribers. As compared to a free server website which nobody likes to visit.

Therefore, making a research before I actually started my internet business has really paid off. I managed to avoid the mistakes made by most internet business starters who jump into any online business and subject themselves to scams.

So, after all this while, I am left to ask myself " What if I have started sooner?" After all, having my own internet home-based business gives me some advantages as to working for a company boss. I do not have to spend the time commuting to office which can be gruesome during the peak hours. i can now choose my own time and dresscode even if that means in my pyjamas the whole day.By spending more time in my online business, it makes more profits and increase s my earnings. An internet business does not require a large capital as compared to owning a traditional shop. Owning a website allows me to run my business 24/7. This will not stop even though I'm enjoying my vacation in some remote places. Everyday, my online business gets exposed to a growing market as more and more people are exposed to the internet. And of course, the most important reason for me to start my internet business is I can have my weekends off as no boss will tell me to come and work over the weekend again.

What Are The First Steps I Should Take For My Home Business?

So you have just started your first home business. Congratulations now the real work begins. No matter what anyone or any company may have promised you before you signed up, building a successful home business will take work. Many home business companies will promise you the world and not deliver anything. I truly believe it is possible to be successful in any home business venture you maybe in. But it will take work, determination and effort on your part. It also helps if you have a committed upline who is willing to help you grow and learn as a business owner. There are many different aspects to building a home business but I will focus on the aspects which I feel matter the most. These are the aspects which will help you build a solid foundation for your home business. So just to clear up the air a little bit, let me point out a couple of facts before we get started. First there is no such thing as get rich quick. Second there is not such thing as only working on your home business 10 minutes a day. Yes you can only work your home business for 10 minutes daily but your results will not be very good. Third if you truly commitment to building a home business, you can and will be successful.

First you will need your own web site. Your replicated site will not work. You will want to drive traffic to your web site. There are different methods of driving traffic to your web sites. First if you have the money you can post ads in newspapers offline. This is a great way to build your home business. Of course the bigger the newspaper the bigger the cost is to advertise. Normally the results will be very good if it is a large publication. You can also advertise in magazines as well. When advertising in magazines try to focus on magazines which cater to the customer you are trying to market to. It makes no sense to advertise in a magazine about fishes if you are selling vitamins. Instead find vitamin magazines. I would not suggest advertising in flyers, they are not really effective and you have to have a lot of flyers spread out everywhere just to get a few prospects.

Next there is online advertising. Normally everyone jumps to the free classified ad sites to post for their home business. Now in order to be effective with free classified ads you have to post a lot. And I mean a lot. I honestly feel it is not worth your time and effort to post your home business ads to free classified ads. First mostly everyone posting on free classified ad web sites is posting their home business opportunity. Next what is going to make your home business stand out from all of the other ones. Nothing, it is a crap shoot when posting on free classified ad sites.

Next PPC or Pay Per Click is a very effective way to drive traffic to your web site. But here is what I suggest unless you already know how to run an effective PPC campaign, hire a pro to run your campaign for you. Remember this is a business just because it is a home business doesn't mean you should treat it any differently. Businesses reach out to contractors when they need help in certain areas and you should do the same. If you have the cash I would even suggest going as far as hiring a marketing firm to market for you.

Lastly you could start an organic SEO campaign to show up in search engines. You could also hire a pro to do this for you but I would be very cautious when looking for an SEO pro or company. There are many out there who have no clue on what they are doing.

When first starting your home business getting traffic to your web site is key. It's simple no one sees your web site, no one buys your product. The quicker you are able to start making a profit with your home business,the stronger your conviction will be that you made the right choice.

Top 5 Reasons Why Your Small Business Needs A Custom Website

Today, in North America, almost 70% of households have access to the Internet. It has evolved to the point where the Internet has become an integral element in the way business is conducted, and is shaping the way business will be conducted in the future. Most consumers these days research a product or service on the Internet before making their purchase. So, in this day and age, it could cost you not to have a website. Listed below are 5 reasons why you should employ an experienced web designer to construct a custom website for your small business.

Credibility & Identity Building
Like it or not, your potential customers are going to judge the quality of your products and/or services based on presentation and image. Therefore, an aesthetically pleasing web site will give you and your company more credibility in the eyes of you customers or clients.

Lower Your Expenses
Why spend thousands of dollars on static traditional media such as brochures? If there was ever a change in your business, such as an expansion or additional products/services, it would require printing all new corporate brochures. A web site is dynamic and can be changed or updated in a very cost effective manner. Best of all, your clients can access this information from anywhere in the world, without the delay of snail-mail. A properly constructed web site can also reduce the time that you and your employees spend answering redundant customer questions.

Complement Your Existing Marketing Efforts
Most people think of a web site as advertising. Unfortunately, they would be wrong - A web site is a medium which complements and enhances your existing marketing efforts. Your potential customers or clients can easily gain access to information that isn't suitable to include in other traditional advertising mediums. In less than a decade, a web site will be just as common as having a listing in the Yellow Pages. What would your potential customers or clients think of your business if you didn't have a web site?

Customer Service
A web site allows potential customers or clients to get to know more about your company, increasing the personal side of doing business. Your business will be open 24hrs per day, 365 days per year, and if someone has a question concerning your product or service, an answer is only an e-mail away. Some people may feel uncomfortable on the phone or in your office / store, and, to these people, e-mail is their preferred method of communication.

Get a Jump on the Competition
A professionally designed web site will make your business appear larger than it actually is, and therefore challenge larger competitors. When it comes to getting listed in the search engines (Google, Yahoo, MSN, etc.), the longer your web site has been active, the higher ranking you will receive, and therefore more traffic will be directed to your web site. It is for this reason that you can't afford delay this important decision any longer.
