More Information
Summary:The present disclosure provides methods for improving processing of GNSS signals. More particularly, the method reduces a bit resolution of a digital signal, by processing, based on a maximum threshold value and on a s-bit resolution value, the digital signal received with an n-bit resolution to generate requantized digital signal with the s-bit resolution. The method further determines an optimal gain of a Global Navigation Satellites Systems Radio Frequency (RF) signal recorder, by determining a range of values of a gain of the RF signal recorder corresponding to a selected range of values of a total noise of the RF signal recorder and RF signal receiver. The method also automatically detects disconnection of a RF signal recorder from a Global Navigation Satellites Systems (GGSN) Radio Frequency (RF) signal receiver, and synchronizes multiple RF recording systems.
