《 software Defined GPS and Galilleo Receiver》源码

This directory contains two data sets for use with the GNSS Software Defined 
Receiver (SDR). 

The primary data set is named "GPSdata-DiscreteComponents-fs38_192-if9_55.bin" 
and it was collected at the University of Colorado, Boulder, CO, USA. The data 
set collected using the discrete component front end design described in the 
textbook and is the primary reference set. The parameters necessary for 
processing these data are as follows: 

 - Sampling Frequency: 38.192 MHz
 - Intermediate Frequency: 9.55 MHz (nominal)
 - Signed character (8 bit) sample format

 
A second data set has also been included. This data set is unique as contains 
the usual GPS data and was recorded when the GIOVE-A satellite was visible and 
transmitting on the 1575.42 MHz frequency (so hcontains data from various GPS 
satellites as well as the GIOVE-A satellite). This data set was collected using 
the NordNav R30 sampling receiver in Turin, Italy and is courtesy of Marco Pini 
and Politecnico di Torino. It is named 
"GPS_and_GIOVE_A-NN-fs16_3676-if4_1304.bin". The parameters necessary for 
processing these data are as follows: 

 - Sampling Frequency: 16.3676 MHz
 - Intermediate Frequency: 4.1304 MHz (nominal)
 - Signed character (8 bit) sample format
