I developed “GNU Radio Beacon Receiver” that measures
total electron content (TEC) of the ionosphere by receiveing
150MHz/400MHz beacon signal from satellites in the low-
earth orbit. Detailed information of the receiver is
published in the following URL.
I hope people permit me to call the reciver by this name.
I very much enjoy coherent design and stability of
the USRP and GNU Radio. The receivers are now used
for real ionospheric studies. I hope more people would
use this receiver. Thanks GNU Radio!
