Thank for your answer!
Do you know where I can found precise ephemeris (sp3)?
I'm not see something complicated like found broadcast ephemeris
(thanks to people on this found to help me) and I suppose that found
sp3 is hard too.
I have two GPS12 and use it for postprocessing, i try with
brdc****.09n and i like to try with precise ephemeris sp3
All best for everyone...

The n means it is a NAV message in RINEX format. The NAV message
contains the broadcast ephemeris, clock correction data and other
subframe 1, 2 and 3 items. the 'o' file is a RINEX observation file -
the actual receiver observations (pseudoranges, etc.) I think m
stands for meteorological file. Check out the RINEX documentation
here: http://www.ngs.noaa.gov/CORS/Rinex2.html for more complete info.
