[Discuss-gnuradio] GPS Receiver Daughter-boards / Antennas

[bagnallb]

Hello,
I am trying to implement a GPS receiver in GNURadio. I am wondering if  
anyone has suggestions on which daughter board I should be using for  
the receiver. I currently have a DBSRX-LF board and also a  RFX1800  
board that both seem to operate over the correct frequencies but am  
wondering if there is a reason I should prefer one over the other.  
(ex. Noise performance, Antenna Interface...) I am also open to  
suggestions if there is another board that I should be looking at  
instead.

Also, I am wondering if there are any suggestions on the antenna that  
I should purchase. It is my understanding that I will need an active  
antenna and am wondering how I should interface it to the board.

From past messages I gather that I will need to provide a DC bias and  
there are at least three ways to do this. What are the benefits of  
using an off-board tee instead of what is included on the board? I've  
seen some antennas that come with there own power supply and thought  
that this may take care of this problem?

Thanks for any help/suggestions.
