Error analysis of GPS signals from USRP using GPS receivers

In this paper the USRP (Universal Software Radio Peripheral) will be explored to characterize GPS receivers. The main receiver will be the Ublox receiver. The errors added to the recorded signals, by the USRP, will also be quantified and analyzed in order to observe any trends. These trends will then be compared to known models to validate the type of error seen. This paper hopes to expand the uses of the USRP, and validate its use as an acceptable, convenient tool for processing GPS data. The paper will also give a better understanding of the errors inserted by the USRP.
