Its possible, its multipath. Depending on your receiver, you can shut
off reception from individual GPS PRNs. Check to see which ones are in
use at the time, and then turn one off. 12 Hours later, turn it back on
and turn off another, etc.
Also, if you can turn off GPS PRNs, you can pick at time common with
NIST and use the GPS archive at
http://www.boulder.nist.gov/timefreq/service/gpstrace.htm to compare
time (use view track to see one satellite by itself).
