And we have yet still to hear what Dish has plans for to use their spectrum assets that they are hoarding.

GPS signals are very low data rate CDMA. So, the spreading gain between the data rate and the signal bandwidth is massive. DBS signals do not have that advantage.

Interesting. Just out of curiosity, what is the typical bandwidth and chip rate for GPS?

L1 and L2 signal bit rate is 50 bits/sec, encoded with a CDMA chip rate of ~10.23 million chips/sec. The bandwidth is apparently about 30 MHz centered on the L1 center frequency of 1575.42 MHz, with most of the C/A code's energy at the center while the P (legacy military) code is more spread out.

^ Thanks, that's a lot of de-spreading gain, especially for the military version.
