autopilot 2.0
  by Tramm Hudson (http://freshmeat.net/~tramm/)
  Sunday, January 13th 2002 10:29

About: autopilot is a command and control system for  Unmanned Aerial Vehicles. It
provides hands-off  flight controls for helicopters and simple "moving map"
control for the ground station. Manual control is similar to operation
under IFR with three axis EFIS. 

Changes: The is the first major restructuring of the code and the first port to the
custom circuit boards. The Rev 1.0 circuits have been produced and hacked.
Static tests have been successful with the ./efis/gs program and the
/onboard/src/flybywire program. The onboard code has been split into a AVR
library and controller program. The Mega163 is the default architecture,
since that is what is socketed on the new PCBs. ADC is polled rather than
interrupt driven and is scaled to the internal voltage reference. A PID
(Proportional/Integral/Derivative) control loop library has been added.  

Release focus: Major feature enhancements

autopilot 2.1
  by Tramm Hudson (http://freshmeat.net/~tramm/)
  Sunday, January 27th 2002 01:04

About: autopilot is a command and control system for  Unmanned Aerial Vehicles. It
provides hands-off  flight controls for helicopters and simple "moving map"
control for the ground station. Manual control is similar to operation
under IFR with three axis EFIS. 

Changes: This version is the second major restructuring of the code. Everything for
the onboard system has been packaged into onboard/avr/mainloop.c and
installs from there. As with 2.0, this requires the custom PCB or an STK500
with Mega163 hooked up with the same connections. The ground station does
not work with the current output due to UART problems onboard.

autopilot 2.2
  by Tramm Hudson (http://freshmeat.net/~tramm/)
  Monday, March 11th 2002 09:41

About:
autopilot is a command and control system for  Unmanned Aerial Vehicles. It
provides hands-off  flight controls for helicopters and simple "moving map"
control for the ground station. Manual control is similar to operation
under IFR with three axis EFIS. 

Changes:
This release adds an OpenGL helicopter simulator for testing out the
inertial measurement system (IMU) and for calibrating the attitude/heading
reference (AHRS). The inertial data, either from the simulator or from the
IMU on the real helicopter, feeds into a Kalman filter that can run on the
ground station or on the realtime board.

Autopilot UAV 2.3
  by Tramm Hudson (http://freshmeat.net/~tramm/)
  Sunday, June 23rd 2002 21:54

About:
autopilot is a command and control system for  Unmanned Aerial Vehicles. It
provides hands-off  flight controls for helicopters and simple "moving 
map" control for the ground station. Manual  control is similar to
operation under IFR with three  axis EFIS. 

Changes:
The simulator and helicopter can now be flown with Futaba transmitter
through our buddybox/trainer port interface. The simulator has been
redesigned to be much more modular and now uses a typesafe vector math
library. The flight controller has a SWIG interface. The rev2 prototype
code is much more efficient and now longer jitters under high interrupt
load.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO v IBM.
