- Rather than asking someone else do your research for you, why
- don't you try a good local library. Since Trimble is only in the
- business of providing receivers and user-specific applications
- hardware and software, I don't think they need to provide random
- callers with technical specs on GPS. From your net address
- (rabjab@golem.ucsd.edu), I am assuming you are near UCSD, which has
- an excellent technical library. I'll bet you money you could find
- 50 or more references in 15 minutes by looking in any of the
- following ...
- - IAF abstracts
- - STAR (scientific and technical abstracts report)
- - AIAA abstracts
- - NTIS data base (National Technical Information System)
- - Aerospace data base.
- All of the above are available in hard copy (except for the last)
- at just about any significant technical library. All are available
- on CD-ROM, or on-line. And they'll give you just about anything you
- want to know from spacecraft constellation specifics and design, to
- full technical specifications for any part of the system.
-
- And if you still don't want to do any of the (minimal) legwork,
- ask the reference librarian at the library what would be the easiest
- way... She/he is paid to help answer questions like this -- but
- she/he doesn't know exactly what questions you want answered.
-
- Sorry Jeff, but I'm in a rotten mood tonight. I've just read
- through about 50 K of useless drivel, posturing, and meaningless
- speculation. Your question can be answered simply, and I'm
- surprized no one else has recommended you just look up the data in
- any of the standard data bases. If you really want to go the
- horse's mouth, call the GPS Joint Program Office (GPS JPO) at Air
- Force Space and Missiles Command in El Segundo, California. But all
- they'll do is reference to some of the reports and papers you'll
- find in the above data bases.
