Hello friends.
I'm very interesting in the resolution of the carrier phase ambiguity, and how to fix the integer ambiguity. I'd like that someone could give me information about this question, or tell me where I can found it.
I'm waiting for your help.

Thanks Guys

There's been a lot published on this; check the Institute of Navigation Proceedings (www.ion.org) as a starting place. This will lead you to other published papers on the topic.

Depending on the amount of detail you want, there are a variety of printed and on-line resources, one of the latter is:

Some books you might consider are GPS for Geodesy and Linear Algebra, Geodesy and GPS details about both can be reviewed at Amazon.com and elsewhere...

HTH,
