GPS S/N unit problem?

I read a GPS application(Altitude determination) paper.
And the signal to noise ratio unit is "Volts per Vote".
I don't know how to explain to dB units.
Can help me by any information?
Thanks!
 

Re: GPS S/N unit problem?

The relation between "volt" and "dB" is
"dB" = 20*log10(volt)
