[OpenSource_GPS] CVS Update

All,

I recently updated the CVS on sourceforge to implement the raw nav data bit recording.

It creates the file navdata.log which is in binary format.

The file format is 12 bytes which indicates the PRN being tracked for each channel.  This is followed by 1500 16 bit words arranged as 2 bytes with high order first.  Each bit holds the data from one channel (i.e. bit 0 is for channel 0 etc.).  This format is then repeated for evey 30 second frame of data.

If anyone has any problems with it or suggested improvements please let me know.

Best regards,

Cliff
