This paper proposes a design method of a CDU(Control Display Unit) for commercial INS(Inertial Navigation Systems). In order to guarantee reusability and extendability, the design method is based on the class programming of the Windows operating system. Since the CDU has abstracted functions and variables, it can be interfaced with any INS. It is also easy to extend the designed functions using inheritance and polymorphism of the class. In order to show usefulness of the CDU, it has been implemented for the H-726 INS.

This paper designs a CDU(Control Disaply Unit) for commercial high precision INS(Inertial Navigation System). The CDU is designed using GUI(Graphic User Interface) programming running on Windows operating system. Since the designed CDU provides standard functions of the Windows operating systems and has a modular structure, it is easy to modify and extend. The CDU has been interfaced to the H-726 INS, from which it's usefulness can be seen.

This paper describes an implementation of a wide-range dimming controller of a LED backlight for Avionics applications such as a control display unit(CDU) and multi-function display(MFD). The digital dimming controller employing a current controlled buck converter and light sensor feedback is proposed. The proposed system provides a wide dimming control range of from 150fL to 0.05fL(3000:1) required for avionic displays. The experimental results are provided to show the control performance.

This paper describes an implementation of a wide-range dimming controller of a LED backlight for Avionics applications such as the control data unit(CDU) and multi-function display(MFD). A feedback controller using a light sensor is proposed to control the brightness in the low dimming range. The proposed controller provides an improved control performance in the wide dimming range of 1:3000 even under the temperature variations. The experimental results are provided to show the effectiveness of the proposed control system.
