CONTROLE D’UNE ANTENNE PARABOLIQUE VIA UN MICROCONTROLEUR

Abstract

The role of the positioner is the orientation of the parabolic antenna to the satellites and save its location manually, after saving, a simple request by the user, the antenna is automatically positioned on the called satellite. In this project we realized by a simulation with program PROTEUS ISIS a control board of a parabolic positioner. The control board contains the 16F877A pic is the "brain" of our positioner because it runs in continuous a machine language program operator's desire servant. This PIC connected to an LCD display to show the rotational state of the positioner and comment interacting with the user. For rotation of the dish used was a stepping motor, the actuator is chosen due to its precision.
