Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Spy Satellite shopping experience:

1. Compare - without doubt the biggest advantage that the Spy Satellite offers shoppers today is the ability to compare thousands of Spy Satellite at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Spy Satellite? Wrong! If the Spy Satellite is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Spy Satellite then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Spy Satellite? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Spy Satellite and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Spy Satellite wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Spy Satellite then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Spy Satellite site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Spy Satellite, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Spy Satellite, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.



A spy satellite (officially referred to as a reconnaissance satellite) is an Earth observation satellite or communications satellite deployed for military or espionage applications. The first generation type (i.e. Corona (satellite) Corona page at NRO Corona page at NASAand Zenit spy satellite) took photographs then ejected canisters of photographic film, which would descend to earth. Corona capsules were mid-air retrieval as they floated down on parachutes. Later spacecraft had digital imaging systems and downloaded the images via radio links.

In the United States, the most information is available on programs that existed up to 1972. Some information about programs prior to that time is still classified information, and a small trickle of information is available on subsequent missions. A few up-to-date reconnaissance satellite images have been declassified on occasion, or leaked, as in the case of KH-11 photographs which were sent to Jane's Defence Weekly in 1985.

Origins On March 16, 1955, the United States Air Force officially ordered the development of an advanced reconnaissance satellite to provide continuous surveillance of “preselected areas of the earth” in order “to determine the status of a potential enemy’s war-making capability.”{{cite book | title = Into the Unknown Together - The DOD, NASA, and Early Spaceflight| last = Erickson | first = Mark | isbn = 1-58566-140-6 | url = http://aupress.au.af.mil/Books/Erickson/erickson.pdf -->
