gps simulation kits problem

[usami2004]

I used the GPS kits example "niGPS Write Waveform To File For Trajectory Mode Simple" to generate outputs. It's said there are satelltes signals 1,3,13,16,20,23,25,31,  but I could not find any signal in the output data.   I double checked, and have no idea what's going on.

I attach the output file.

Can I ask how you are verifying that there is no signal in the output data.  Are you just running the Streaming File Output example with your bin file and checking the spectrum?  Can you run one of the example .bin files such as the everest one and see if anything is generated?
