Question

Hello everyone!

My name is Marten Vohrmann,i am a student of Electrical Engineering at the University of Paderborn.

Our aim is to develop a Software-GPS which is based on the GNU-Radio Framework. Unfortunately the project is stuck, because we need to convert our raw-data into the RINEX-Format for further work on positioning software.

Our recorded data is of type complex (C++), does GPStk offer any kind of converting function, which converts our complex-data-stream into RINEX-Format. I've already looked through the Doxygen-doku, without luck.

I am looking forward hearing from you.

Have a nice weekend!

I'm assuming by a complex type you mean the samples have yet to be translated into pseudorange/phase measurements that would be suitable for storage in a RINEX file? We have some code that does a software receiver tracking and signal simulation. It is located in the apps/swrx directory. Take a look in there and see if that is what you were looking for.

Thanks for answering my question so qickly! We are operating with the Ettus Board and this device delivers us a file or data stream, which only contains the raw data that comes out of the ADC of the device. For futher work we need to transform these data into a correct format. So is there any kind of code that converts our really raw-data into RINEX format ?

I would say it is unlikely we have exactly what you need. However the code in the swrx directory should be a good start at that. We have used it with our own custom hardware to demodulate the C/A code data into pseudoarange/phase and navigation data.
