... Spilker (11) indicated that a 1-bit ADC degrades the signal-to-noise ratio by 1.96 dB and a 2-bit ADC degrades the signal-to-noise by 0.55 dB. Many commercial GPS receivers use only 1- or 2-bit ADCs. Chang (12) claims ... selecting a GPS antenna a trade-off between the maximum number of receiving satellites and interference must be carefully evaluated. If an antenna has small g...
