Well, you would think so...
There is 37 PRN codes, of which the top 5 is for testing.
However, in the modern ICD:
http://www.gps.gov/technical/icwg/IS-GPS-200H.pdf
you will find that there is an extended set of PRN codes, and for the
C/A code the modulation is the same, just that the transmitted PRN is
shifted. This extended system can hold 64 active birds in the constellation.
Cheers,
Magnus

The GPS system is pretty much limited to 32 active satellites. There are
currently 29 satellites broadcasting usable navigation data. Plus some WAAS
signals from geosynchronous orbit.
