The files containing the GPS SVN49 L5 data collected by a NovAtel EuroPak-15a receiver
operating at the University of New Brunswick (UNB) in Fredericton, Canada, between days
102 and 108 inclusive, have been replaced. The L5 pseudorange data in the original
files contained large ambiguities due to the fact that the receiver did not relate its
GPS49 L5 measurements with its L1 measurements and the absence of navigation message
bits on the L5 signal. However, the measurements with the ambiguities are easy to spot
and correct and this has been done in producing the new files.

As before, the files are available in both RINEX 2.11 and 3.00 formats. The directories
are

ftp://cddis.gsfc.nasa.gov/pub/gps/data/l5test/rinex2/daily/2009
ftp://cddis.gsfc.nasa.gov/pub/gps/data/l5test/rinex3/daily/2009
 
Tracking of SVN49's L5 signal at UNB is a joint effort with the German Aerospace
Center (Deutsches Zentrum fuer Luft- und Raumfahrt or DLR).
