Hi,
I am trying to collect signal from Thuraya-3. Here is the setup I used:
- USRP N210 + WBX
- LNA with 30dB gain (ZHL-1217MLN)
- Iridium Antenna (I don't have specific antenna for Thuraya right now.
Since Iridium and Thuraya frequency bands are quite close, I suppose it
would work more or
The polarisation loss in your case might be 30 dB. Have a look into that.

Vanush

Hi all,
Thanks! I'll give it a try once I get a LHCP antenna.
Best regards,

Hi,
I think it's TDMA/FDMA, not spread spectrum. Each channel is about 30KHz.

Make sure that you're tuned to the correct frequency, and that your link
margins are adequate. It could be that your antenna has insufficient
gain
Cheng,
The resources I've read say that the downlink is 1525-1559 MHz, which is a
ways off from Iridium's frequency of 1616-1626 MHz.
This would suggest that you should find a different antenna, like this one
which covers both bands:
Also, apparently, the two systems have opposite polarization:
