o CC2NONCC utility is used to convert a RINEX file from a receiver
which uses the cross-correlation technique to pseudorange
observables compatible with the modern pseudorange tracking.
o Specifically, the C1 and if necessary the P2' (equivalent to C1
+ (P2-P1)) pseudorange observables of cross-correlation
receivers are replaced by C1 --> C1 + f(i) P2' --> P2'+ f(i)
where f(i) are empirically-determined long-term average valuesi
as a function of GPS satellite PRNi.
o In addition, a few models of non-cross-correlator receivers
report the C1 observable rather than P1. For these types, only
the C1 is replaced by C1 --> C1 + f(i) and the P2 observable is
o the main program file header (cc2noncc.f) and the make files
should be read for compilation and further instructions. Please
use the p1c1bias.hist above with cc2noncc and keep it updated
with the monthly P1C1 values published at the CODE ftp server
