Re: [Discuss-gnuradio] Baseband GPS OTA USRP capture that anyone can share?

This is the web page I was looking for. http://www.rtklib.com/rtklib_sdr.htm I myself have never used RTKlib with an SDR. Try to use a circularly polarized antenna. GPS signals are circularly polarized to allow the antenna to have some degree of rejection of signals reflected from the ground.

Hi Philip, How does the conclusion be made that ARM can not swallow the current max data transfer rate? I need to build a project that need to process 60MB/s data, so any way to achieve my goal. Use a more powerful CPU or use dsp on the omap? On 5/25/12, Philip Balister wrote: > On 05/24/2012 09:

Hi, I installed the latest version of gnuradio and gnuradio-companion a few weeks ago. The "Graphical Sinks" option of my grc has two blocks: Eye Diagram and Fast AutoCorrelation Sink. I am following a grc tutorial ( http://www.csun.edu/~skatz/katzpage/sdr_project/sdr/grc_tutorial1.pdf). The auth

Is there a one-stop-shop command to disable building GNU Radio without the GUI? I want to save build time on E100 and don't need it. My best guess is "cmake -DENABLE_GR_WXGUI=False ../", but I don't know if there are other dependencies or GUI components that also can be explicitly disabled. Tha

Dear gnuradio list, I have built a new module using the create-gnuradio-out-of-tree-project command. Now I would like to add new blocks to this module. Writing new .h, .cc and swig-files is not a problem, but obviously I have to adapt some Makefiles etc. I thought, it would be a good idea to t

Hi! I have a short question: in my implementation of a state machine to implement a parser for a MAC sublayer standard (802.15.4) I used a Sync-Block. Now I found out that carrier_sense() is only in gr_packet_sink class. Does this make sense at all? Normally I'd apply some Carrier Sensing right be
