How Does a GPS Work?

Your GPS unit communicates with satellites, which send out radio signals. Since the speed of those radio signals is a known factor, the GPS receiver is able to use that speed to calculate its distance–and therefore the distance of the one holding it–from a satellite. This calculation puts you and the GPS in an imaginary sphere.

So imagine yourself holding your GPS and standing in a big circle (See: “A” in the above image) on the ground. This reflects the information from a single satellite.

The GPS will do the same thing with the other satellites with which it can communicate via a clear line-of-sight. So for the second satellite, imagine another circle which intersects with the first. (See: “B” above) This second calculation will put your near the intersection of the two circles (See: “A^B”).

Then add a third satellite and another intersecting circle. This third calculation will place you in the intersection of the three circles. This is considered a “2D” (or two-dimensional) mode, figuring your location horizontally only. In this case, you can input your elevation, if you know it, for more accuracy with the GPS unit. Keep in mind that 2D navigation can be unreliable.

If your GPS can communicate with 4 or more satellites, your location will be more accurate and you’ll be in “3D” mode, which will include an elevation calculation. This is what you’re aiming for.

Your unit display will indicate whether you are in 2D or 3D mode. If it’s displaying 2D, try moving around and getting into a more open area, free of obstacles like tall trees, to hopefully get to 3D mode if at all possible.

**You should always check your “EPE” or “Estimated Position Error,” which will display on your GPS, usually right on the same screen that indicates how many satellites it’s communicating with–the satellite page. This will also show you how accurate, or perhaps inaccurate, the position fix is. An EPE of 20 feet or less is good. The lower the EPE the better.

How Do You Use A Portable Gps?

Portable GPS receivers are becoming more popular- everyone from hikers to fishermen and hunters to recreational geocachers are finding reasons to put a portable gps on their wish list. Global positioning satellite technology has never been so easy to use as when it is packaged into a portable GPS you can take with you wherever you go.

One of the most common uses of a portable GPS system is within cell phones. For the first several years that cell phones were popular, they had a serious drawback- you could contact 911 or other emergency services, but if you didn’t know where you were, neither did they. Cell phones have no location, as a landline phone does, and there was no way to track where they were sending signals. All that has changed with the advent of the portable GPS. Now, your cell phone can come equipped with the potentially lifesaving feature of global positioning satellite technology. By using the same 24-satellite system and triangulation procedure that GPS systems installed in vehicles use, a portable GPS can pinpoint your location- in some cases down to mere yards. This feature can absolutely save lives in the event of an emergency.

Cameras are also being made with portable GPS systems in them to enable photos to be imprinted with both longitude and latitude of the photo. You can also tag your photos to integrate with an online map so you can see exactly where your photo was taken.

It’s easy to understand how a portable GPS can be helpful when you are hiking or camping. Imagine the freedom gained when you no longer need to worry that you might get lost and be unable to find your way home. Of course a GPS device is no substitute for care and caution and should never be considered infallible, but there is no doubt your horizons can be expanded when you have this kind of precision help in finding your way.

Recreationally, in addition to using a portable GPS for hiking and camping, hunters can use one to find that secret lake, scout out the perfect spot for a deer stand or tracking nearly anything. In addition, the sport of geocaching uses a portable GPS to seek out hidden “treasures” and can provide outdoor activity and fun for the whole family.

How to Find the Best Internet Marketing Software to Market

There is a trend happening in the sector of internet marketing software. If you actually open your eyes and focus on everything in the internet marketing world, you’ll notice this express trend that is rapidly invading our email inboxes from every internet marketing software guru out there. This trend is a marketing shift from text ebooks to more high valued products like multimedia online displays and software products.
in times past, many people have made tremendous fortunes online selling ebooks only. But the days of making significant money from writing your own text ebooks is now over. Many internet marketing professionals recognized this and straight away modified their marketing battle plan. Plenty of them jumped right into the internet marketing software industry to tap into the wealth of revenue that many individuals like Bill Gates from Microsoft and Larry Ellison from Oracle are already achieving.

Now the internet marketing software and technology industry has been known to create many multi millionaires and even billionaires. Due to the large number of millionaires in the software industry, I can conclude that lots of internet marketers who essentially dive into this industry and actually use practical internet marketing principles to market their internet marketing software will also become millionaires.
This transition is a particularly smart move and I personally recommend everyone concerned in internet marketing to become involved in the software marketing industry.
prime quality heavyweight software is usually pretty dear and will harvest a nice profit per sale. When I speak of high quality software, I am speaking about any software that will get you over $75 in profit. If you are truly looking to earn a millionaire fortune online, you can not sell any cheap software that will earn you between $10 to $50 per sale. Bill Gates won’t be the multi-millionaire he is today if he just sold cheap software.
extraordinarily high quality software does not saturate the internet like conventional ebooks do. You wish to sell unique internet marketing software that is of the highest caliber. The explanation why the ebook marketing craze is over now is actually because ebooks have literally saturated the web world. Ebooks were very good in their first days, but it ultimately evolved into a difficulty where every electronic book you read will say the same thing with a slight twist.

Also, most of the information found in ebooks can be found online for free by doing intensive research on the internet through search engines and niche directories. Online marketing professionals have noticed this decline, and straight away shifted over to selling prime quality internet marketing software items instead.
Software, for many years, has been known to clear up a multitude of categorical issues that not even one educational ebook can solve. Software makes the task of the user of the internet marketing software less complicated, and that’s why it is in high demand. Because of a high demand in software applications, a marketer can easily make a particularly worthwhile sale just from exploiting everyday online marketing concepts. People will always love and need new software.

As you can see from the three reasons listed above, marketing software via the internet is the new wave that is hitting the internet marketing world. If you are really serious about sustaining your career in internet marketing, you must think about transitioning over to marketing internet marketing software products on the web. There are huge profits that will still be reaped in this software industry. And when I say large profits, I mean it.

How To Avoid Legal Trouble From Trademark Infringement When You Buy A Domain Name

So you have a hot idea for a website, or maybe you want to capitalize on a hot new product that has just been released. There are some things that you will want to know first before you get yourself in a lot of hot water.

Choosing a domain name isn’t really rocket science but it is very important. You want to choose something that is as short as possible, easy to pronounce and remember for marketing purposes, and if at all possible you want to get your main keywords in the domain name. All that aside, you also have to be careful that you don’t step on the toes of a person or company who may be inclined to sue you.

For example, judges have ruled against domain name squatters in every case where they registered a celebrity’s name. They will also rule against companies that infringe upon other companies. A good case in point would be the case a couple of years ago between the World Wrestling Federation and the World Wildlife Foundation. The World Wrestling Federation called itself the “WWF”, put up a website at wwf.com, and the World Wildlife Foundation filed a trademark infringement suit against them. The Wildlife Foundation won because they had been in existence for many years before the wrestling firm and therefore the World Wrestling Federation had to change its name to World Wrestling Entertainment. Obviously this cost them a great some of money to change their name that appeared on millions of marketing products all over the world as well as the expense they had put up on their website and online marketing.

Another more recent issue that is still ongoing is the battle between Apple and the V.O.I.P. product “iphone” from Cisco. Apple announced they would be bringing a product to market called the Apple iPhone to go along with their other products that start with an “I”. Cisco promptly filed for injunctive relief and as of this writing the issue is unresolved.

There are a few basic guidelines that will help keep you out of trouble when you are choosing a domain name so you don’t run into legal trouble from violating someone’s trademark. Let’s take a look at them.

First off you need to realize that a name that is used to identify a particular service or product is a recognized trademark. Trademarks that are deemed to be suggestive and memorable are granted protection by both state and federal law.

A confliction of trademarks occurs when one trademark is in conflict with another and the deployment of both is probably going to be confusing to customers or would be customers concerning the company’s products or services. As I illustrated above, when the legal issue is with a later user of a trademark, the law rules that the first commercial user of the trademark is the legal owner and is therefore given protection. The loser will be forced to cease using the trademark and may even be compelled to pay damages to the original owner, particularly if it is determined that they were malicious in their intent.

The smart thing to do is to consult a trademark lawyer and have them check out your idea for a domain name before you invest too much in developing and marketing it.
