		      Open Source GPS To Do List
		      --------------------------

* General improvements

** Get it to work using interrupts from the card (must have newer
   version of the card with these interrupts available)

** Allow data message to output every six seconds with full frame
   information and keep user side working in sane manner.  Likely
   involves keeping an old copy so you can see which part has changed
   since last sub-frame.  (don't look at sub-frame number from status,
   that's lame and might have timing problems.)

** WAAS support
    - Need previous problem solved at a minimum
    - Step 1: Add WAAS PRN codes and search for them
    - Step 2: Verify you can track a WAAS satellite
    - Step 3: Data pull off changes since it's 5x data rate.
    - Step 4: Fix user side for this data change
    - Step 5: Implement DO-229c on user side.

** Add a matrix math library (file) so we can do Kalman filters and
   other higher level math stuff.


* Linux Specific


** Figure out an elegant solution to number of doppler search bins bug
   when you don't have an almanac.  Dilemma: The number of search bins
   is large if doing cold search in device driver and automatically
   reduces when channel is assign.  However, userland cold search
   assigns channels and messes up the whole idea. Obvious solutions
   are to either not do cold search on user side at all (this might
   break the DOS version) or allow user side to control number of
   search bins.  I don't like the second one because it would mean
   modifying the interface.

** Write another user side program that uses the device driver to
   allow for more testing of interface and show flexibility.  Perhaps,
   re-use some other open source GPS libraries from other groups to
   make these easier.

** Add support for gpsd so we have a moving map via something like gps
   drive.

** Allow the user program to set the system time if it has authority
   to do so.  (root permission?)

** Integrate with other kernel time setting code to allow for
   extremely accurate time control.  (this could be really useful for
   certain applications.)


* DOS Specific

** Get PCI assembly working for DOS and Borland C 2.01 

** Get the DOS version to use the RTC instead of timer interrupts
   (mostly just for consistantly with Linux version.)
