Re: [Discuss-gnuradio] Change of daughter board

Hello Umer, You do not have to burn a new image to the SD card. The only reasons I can think of for burning a new SD image is if you were upgrading the firmware or modifying FPGA behavior. The only modification to your software should be to change the receiving frequency to one that falls in the

Re: [Discuss-gnuradio] Anyone do you know good GPS receiver Method?

Hi folks, My group is using USRPs to do the task Kouki described, although our flow diagram is a little different. We only use the USRP2 to receive the raw RF data which is written to file. This data is processed to the point where we decode the navigation bits, but no position is ever found. W

Re: [Discuss-gnuradio] USRP for GPS

Hi Walter, My group is using the USRP to record raw RF data at GPS and GLONASS frequencies. We do all of our signal processing in post right now, but are interested in developing a stand alone receiver. If you search the mailing list you'll find some other folks who are implementing GPS receiver

[Discuss-gnuradio] GPS L2C Implementation on E100 FPGA

Hi all, I am generating my masters thesis proposal and I have a few questions about the capabilities of the E100 and the feasibility of my project. I have read other posts to gather information, but correct me if anything I've determined is wrong. My goal is to implement an 8 channel GPS L2C rec

Re: [Discuss-gnuradio] File Sink & Buffering

Hi Ryan, What version of GNU Radio are you using? I'm working with the USRP2 to collect GPS data and I have a similar scheme: I have a cyclic buffer that holds data that was recorded just prior to a triggering event. Once a trigger event is received, incoming data is written to an open file sink

Re: [Discuss-gnuradio] Daughter Board ID List

Thanks for your quick response Marcus! I neglected to mention that I am trying to support research that inherits code requiring the "classic" GNU Radio system. I fully intend on using UHD expressly for the reasons you specified once the PhD I'm working with has finished and moved on. Since I'm o

[Discuss-gnuradio] Daughter Board ID List

Hello everyone, I'm just diving into the GNU Radio/Python world and have been doing some "Hello World" sort of exercises to become more familiar. Currently I'm working on a python program to pole my USRP2 and return pertinent daughter board information. I am running GNU Radio 3.4.1 on Ubuntu 10.
