You should be good, then, since the developers obviously accommodated a
The statement quoted from the original article ("GPS receivers
initially were built to accommodate up to 31 satellite signals...") is
incorrect. The PRN range for space vehicles has always been 1-32. (see
Table 3-I in
http://www.navcen.uscg.gov/pubs/gps/icd200/ICD200Cw1234.pdf ). The
concern is that the code in some GPS receivers was poorly written, and
set up data structures to support PRNs 0-31, even though PRN 0 is, and
has always been, undefined.
So problems are not a matter of the age of the receiver, but the
quality of its programming.
