Dear all,

Please find a new version of the cc2noncc program in the links below. 
This program is still important to correct C1 (and P2) observations 
from many receivers which may not report P1 or which may be 
cross-correlator receivers.

The cc2noncc was created by Jim Ray and is currently maintained at 
ESA/ESOC by me. The new version can handle and correct files with 
more than 9 measurement types.  These RINEX files are still not 
common but some stations have started to report 10 measurement types 
which the previous cc2noncc could not correct:

     10    C1    P1    P2    C2    L1    L2    S1    S2    D1# / TYPES OF OBSERV
           D2                                                # / TYPES OF OBSERV

These files are now handled correctly.  You may find the new version 
of the cc2noncc program here:

http://nng.esoc.esa.de/gps_data/CC2NONCC_ESOCv6.1.tar.gz


please refer to previous IGSMails for further explanation and clarifications:

[IGSMAIL-5781]: new CC2NONCC ... correction
[IGSMAIL-5662]: Updated p1c1bias.hist
[IGSMAIL-3887]: TRIMBLE 4700
[IGSMAIL-3737]: C1/P1 biases for Leica and Trimble 5700 receivers
[IGSMAIL-2827]: Monitoring (P1-C1) code biases
[IGSMAIL-2744]: new pseudorange bias convention

etc, etc,

The header of the cc2noncc.f file has all the original documentation
from Jim Ray which is invaluable.  To compile please follow the compilation
instructions in the two make files (cc.gmake and cc.make for each 
target system as explained in the header).  The compilation will 
generate a binary; /cc2noncc/bin/cc2noncc.bin ready for use.

Please let me know any problems you may encounter with this version 
so that I may correct them promptly.

Sincerely,

Nacho Romero


P.D.-  Please remember that a valid p1c1bias.hist file is needed to 
run this program.  I have uploaded an unofficial version of this file 
for your perusal here with biases from CODE updated monthly for the 
last year or so:
