Hello, it’s a pleasure to greet you. I need some information and would like to know if you can help me with a maritime project. I’m currently trying to find a way to detect marine fishing buoys from a fishing vessel. These buoys are satellite buoys that typically operate in the L-band frequencies of 1616-1626 MHz (Iridium or Imarsat), emitting Short Burst Data (SBD) bursts. With a small SDR, I’ve managed to capture the signal from the buoy, but only at a distance of a few meters with a large Noeelec antenna and a SAW LNA filter. The problem is that I don’t want to capture the satellite signal, but rather the signal emitted by the buoy itself. The buoys emit a weak signal; I’m not interested in the message they transmit, but rather in knowing their approximate location within at least 2 nautical miles or at least 5 km. Could the hardware you sell help me with this? I want to know the direction of the incoming signal and its proximity. I know other antennas are needed for this, so I’m asking for your advice. If you have anything else to offer, in short, I want to detect the direction of signals from L-band buoys.
