How to do Post process GPS? Help.

Question

Hi,

I'm new to GPS world. I need to know how to achieve Post processing DGPS. I read the basics in the net. while searching for the providers, i found that in noaa web site, the CORS data Rinex files are available to public for free to download.

Now, I didnt get what should i do to use this downloaded data to post process my gps data. Is there any free post process software available? And I use android phone htc magic as the gps receiver. I also need to figure out how to enable gps logging into file in my android application so that the gps data can be used for post processing.

I found in the net what is dgps and post processing etc.. but, couldnt find clear steps to do post processing dgps.

Your help is greatly appreciated.

Thanks.
