I found one very cool article about SNR estimation in the GPS (BPSK DS-SS signals).
I implemented the RSCN algo (code in octave it may changes bcoz it's link to the my work vcs and this realisation is test, I'll stabilize the code later). The description of this algo you can find in [1, 2, 3]. The [1] is the simplest article from all others ([2, 3]). And in the [3] authors tell that this algo is very sensitive to phase. And it's pretty simple to look. For example we have GPS fronend MAX2769, 16.368Mhz is sampling freq.
