S/N of the combined days is 16.0 dB. Adding the two days non-coherently gives only 9 dB. I couldn't get anything useful out of the nighttime signal. I'll be glad when you get a GPS locked carrier, it's a bit tricky coherently combining recordings when the frequency is not known! -- Paul Nicholson --
