Hi, I released my beacon satellite receiver a while ago. Now I'm releasing my ionosonde receiver. It can be used to perform oblique and vertical ionospheric soundings with ionosonde (and over the horizon radar) transmitters all around the world.
The GNU Chirp Sounder is a software defined radio based receiver for monitoring ionospheric sounders. The software is based on gnuradio and relies on Ettus research USRP2 and USRP N210 based digital receivers. The receiver can be used to receive the whole HF band (typically at 25 MHz bandwidth) simultaneously, and to receive multiple sounders simultaneously. The current receiver can be used to perform single or dual polarization (channel) soundings. The dual channel recorded can be used to determine the polarization form vertical soundings, or for angle of arrival measurements for horizontal soundings. http://www.sgo.fi/~j/gnu_chirp_sounder juha _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
