GPS Satellite Achieves 20 Years In-Orbit

Posted by admin on December 9, 2010 No comments

The Global Positioning System recently celebrated its 20th anniversary. The US Air Force program has come a long way and is looking forward to many more years of technology and development.

On December 10, the United States Air Force celebrated the twentieth year of GPS systems in orbit around the earth, marking two decades of offering critical mapping data for government, commercial and personal use.

The Global Positioning System owes its success to Space Vehicle Number (SVN) 23, launched by Boeing (then the Rockwell Corporation), on November 26, 1990. The satellite was operational for navigation and timing two years later. Though it was expected to last just 7.5 years, with some repairs, it is now slated to live well into its 21st.

Originally, the satellite, Boeing’s GPS Block IIA-10, appeared to be a failure. In just its first year, the satellite’s ability to keep its solar arrays directed toward the sun appeared to be damaged and required the Air Force’s 2nd Space Operational Squadron to manually point the arrays toward the sun for fourteen years. The machinery appeared to fix itself three years later. To date, the satellite maintains one of the best atomic clocks of the GPS fleet.

Global Positioning Systems remain under the purview of the US Air Force, and work with companies like Boeing to maintain the program, which have become critical to American infrastructure for government, private businesses and the general public. There are now 31 satellites in the GPS constellation of varying models.

In the two decades since its original launch, the Global Positioning System has been used for both military and civilian uses, and the GPS system continues to improve. Boeing launched the first of its twelve IIF satellites in August of 2010, and it is the most advanced Global Positioning System in history.

As Global Positioning Systems become more advanced, programs in space, home control and civilian uses will become nearly perfectly synchronized. With these technological improvements, satellites can utilize GPS to become the standard of timing, positioning and navigation.

Digital Product Protection ? How to Protect Your Download Page

Posted by admin on December 9, 2010 No comments

If you sell any kind of digital products online such as an ebook, script or software online, then you will need digital product protection.

It is not easy to stop digital piracy completely, but at least you can make it a lot harder for people to steal your product illegally.

Here are a few ways you can protect your digital product.

Thank You Page

One of the easiest ways to protect your download page or thank you page is to name it with random characters. It will make it difficult for people to guess what your thank you page would be.

It is quite easy for people to find your thank you page if you simply named it as download.html or download.php. Don’t believe me, just do a search on google for these terms and you will be surprised at how many results are returned.

Use Robots.txt

Using robots.txt can help prevent search engine bots from crawling your download page and listing it in the search engines.

Encrypting Paypal buttons

If you are using paypal as a payment processor, make sure to encrypt the pay button. It is easy to know your download page when users can simply open your source file and see the download page location. Paypal provide an option to encrypt your payment button easily.

There are also many digital product protection software that can make the task of protecting your download page a lot easier. You can specify the download time, download limits, limit the iP address as well as many other options.

You have worked hard to create your digital products and should not allow digital pirates to steal your hard earned profits.

Have You Been a Victim of Personal Data Loss?

Posted by admin on December 9, 2010 No comments

Well it seems that you are not alone, according to one headline news there are more than 280 million people around the world are reported to have found themselves in the same position during the last three years.

Today we live in digital-era; we work with computers or other digital media and gadgets. We rely more than ever on our personal computers (PC) or personal digital assistant (PDA). Personal data such as photos, internet bookmarks, email, contact lists, financial records, and office documents are some of the data difficult to replace.

Most people don’t realize how much they have invested into the data on their digital storage like hard drive or removable USB disk. Just imagine how depressing and disastrous we are to know that some day these valuable data gone forever in a second just because of the hardware failure occur suddenly or other common causes. These could cost you several days of productivity. While we are living in the super busy world, time is money, and then you should ask yourself “How much is my time worth to me?”

What would you do if you lost all of your data today? As data loss can happen in many ways without warning at any point in time and you perhaps have “everything” saved on your computer hard drive then you should think about backup routine as soon as possible. Having a good and reliable data backup is like having a “life insurance” for your important data. You don’t have to suffer business downtime, loss of time and money, and loss of business reputation.
