BLITZORTUNG TRACKER eXTendet
============================


---------
Changelog
---------

Version 3
* Corrected signal display (switched colors, ...)
* no more serial buffer delay
* Added remote debug option to send raw board output to Blitzortung servers

Version 2
* Increased serial buffer: Prevents "unknown sentence" or 
  "lost GPS" messages under some Windows systems
* Workaround for changing system time
* no "signals filtered" logging to syslog
* no sending to same ip and port two times
* minor (compiling) fixes

-----
Usage
-----

Windows
* If you do not have experience with the command line, then
  do not try please!!! A GUI will be released soon.
* Download blitzortung_tracker.exe and cygwin1.dll
* Put both files in the same directory, open the command prompt 
  there and start blitzortung_tracker.exe

Linux
* Look in the blitzortung_tracker.c for compiling information
* You may want to use the init script "blitzortung_init"



-----------------------------------------------
New features compared to original Linux Tracker
-----------------------------------------------


- Runs as command line tool under Windows and Linux
    --> needs no special libraries for compiling!
- Integrated HTTP-Server
   * live view of current parameters, statistics and long time values
   * live signals, with sound
   * support for smartphone view
   * tested with Firefox, Chrome, Safari, iPhone, IE9
- Watchdog
   * checks if board is running
   * reconnect if serial port vanishes (i.e. after USB reconnects)
   * resets values after reconnect
   * init GPS only if needed
- Remote parameter updates
   * Admins can change values individually
   * this can improve overall performance/accuracy of your tracker and the whole network 
   * privacy: you have the possibility to disable the updates
   * privacy: tracker pulls parameters from Blitzortung, uses easy HTTP-Transfer 
       --> Admins cannot access the tracker itself!
   * transparent: you can always check the requested parameters by calling the given URL
   * Examples what Admins can do for you:
      + changing the way how the interference mode works
      + adding filters if your station has problems with interferences
      + add fallback server while tracker is running if main computing server is down
      + disabling station when thunderstorms come closer -> prevents false positions
      + show a short message, if station or tracker has problems
- Other way to calculate smoothed GPS position
- do plausibility check of GPS time
- Faster restart of normal operations after faulty message/position (before: >30s, now: >1s)
- Add 2nd server for other network/region with different username/password
- Signal Filters (maximum/minimum) with option to enable filter on interference mode condition
- Password check (only as information)
- 2nd interference mode that considers signal rate
- more debug output
- if interference mode switches on, info message is send immediately
- updates IP of computing server from time to time (no restart needed if DNS changes)
- auto search device option (experimental, but works under Linux and Windows)
