This search engine helps you find documents in the Sat-ND archive. Please note that while the use of this tool is completely free of charge, access to complete articles requires a subscription.

1. Type your keyword(s) in the search box.
2. Select whether you want to search the complete archive ("search index: [ all ]") or only within a certain year (starting 1997).
3. Select how the search results should be sorted: either by relevance, date (latest first) or date (oldest first).
4. Press the Search button to start your search.

Please note:

• Some very common words, such as the, where and one that appear in practically every text are not indexed by the search engine in order to increase performance. If used as keywords, it will be indicated that they have been ignored. In this case, please try to think of other keywords (see also the Galileo example below.)
• All articles are in British English but regularly contain quotes, proper names (such as "Kennedy Space Center") etc. in American English. If you look for the word fibre, also try fiber. Similarly: defence and defense; centre and centre; manoeuvre and maneuver, aluminium and aluminum, etc.
• Searches are case insensitive and accent insensitive. Searching for europeenne also finds Européenne, etc.

If you find a large number of results, try to use more keywords, and/or limit your search to a single year.

Example: if you use galileo as the only keyword, you'll get more hits than you want. Galileo is both the name of a planned navigational satellite system as well as that of a space probe. To find articles about the latter, try to think of words that are likely to appear in articles about the probe but not in articles about positioning satellites. You could for instance type in galileo jupiter. In such cases, please make sure to select "all terms" in the search box. Alternatively, type in +galileo +jupiter (see below for a detailed explanation of this syntax).

Including or excluding words

To make sure that a specific word is always included in your search topic, place the plus (+) symbol before the key word in the search box. To make sure that a specific word is always excluded from your search topic, place a minus (-) sign before the keyword in the search box.

Example: To find articles about Christmas in Australia, but not about the country's Christmas Island, type +australia +christmas -island. (Please note this is a hypothetical example as there are no articles about Christmas in Australia in the archive.)

Expand your search using *

By typing an * within a keyword, you can match up to 16 letters.

Example: Type *elsat to find articles about Intelsat and Eutelsat.
