Hi Martin,
I would like to add a small correction to your mail: GNSS-SDR is actually using GNU Radio for everything! We use several custom GNU Radio blocks to implement all the GNSS receiver operations (Acquisition, Tracking, Navigation message decoding...) even we use a GNU Radio block to obtain the Position, Velocity, and Time solution... What we do not use is the Python wrap. All the blocks and the flowgraph are instantiated directly in C++. More on this, we have native support of UHD Ettus devices (by instantiating the UHD GNU Radio source block) and RTL-SDR (as a normal GNU Radio block also...). We make use of file sources and file sinks to play and record off-line GNSS signals and its processed derivatives... So, in fact, the core of GNSS-SDR is GNU Radio :-) Best regards, Javier. -------------------------------------------------------- Dr. Javier Arribas Lázaro Researcher - Communications Systems Division Statistical Inference Department Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) Parc Mediterrani de la Tecnologia (PMT) Av.

Have you checked the http://gnss-sdr.org/ website? They don't use GNU Radio, but it would still overlap a lot with what you're suggesting. As you've probably read, we can't promise to find a mentor for this. But the idea sounds interesting! I recommend you go the usual route of setting up a proposal.

I would be very thankfull if the team would let me know if GNU Radio is interested in this kind of approach for GSOC 2014. My name is Damian Miralles, I am a senior computer engineering students at the Polytechnic University of Puerto Rico. I am very interested inparticipating into the GSOC 2014 program and saw some of the ideas posted there by Gnu Radio. I have a previous experience working with GNU Radio developing customs blocks for SDR applications. The reason why I am writing is because I would like to migrate some of the experience I have gained during the last year into the GNURadio platform using the GSOC 2014 program. Below is a description of the two possible projects that I would to propose to the GNU Radio group, I will be really thankful if anyone would let me know if it's of GNU Radio's interest. 1- GPS L1-L2/GALILEO Signal Generation The GNU-Radio project includes excellent libraries for SDR, but sometimes a piece of hardware is required to test the code or develop new concepts. The idea behind this project would be to provide the GNU Radio project with the ability of generate raw GPS/Galileo signal through software. Those generated signals would be realistic in terms of noise addition, multipath, interference etc. With this capability the user of GNU Radio would be able to control certains parameters in the data simulated and test if the algorithms developed for reception are suitable. I could easily offer more details on how to create it, here it is only offer a basic idea. 2- GPS toolkit. Create GPS receivers capable of performing the GNSS lock, the kit would include the basic approach for GPS signal acquisition, which include the "Parallel Code Search", "Parallel Frequency Search", etc. In addition I plan to include new techniques for GNSS signal acquisition based on the work developed in: http://people.csail.mit.edu/fadel/papers/quicksync-paper.pdf Please I know the mailing list have a lot of work to due but If someone would let me know if it is of GNU Radio interest would be perfect.
