DESIGN OF SMALL SATELLITE TESTING BED FOR THERMAL CONTROL SUBSYSTEM AND INTERFERENCE IMMUNITY

Abstract

In this project, we have designed a test environment for the small satellite include some of the factors faced by satellite in outer space , we have focused on two types of tests :the first test is thermal effect test, it was done by using PROTEUS ISIS program, to design the thermal control system we Connect the thermal sensor ( LM35) with micro controller And the source of heat and last for cooler and LCD screen In order to test the heat source of the satellite occupy the source of cold and when testing the cooling source of the satellite occupy the heat source, we used two types of micro controller : ARDUINO UNO which programmed by ARDUINO IDE and re-test using ATMEGA 16 programmed by Micro C language because this language compatible with all micro controllers. The second test is interference immunity test, it was done by measuring the shield effectiveness because when shield effectiveness of some devise has a high value that mean this devise has a high immunity from electromagnetic interference, we used MATLAB program because it has excellent feature for plotting that determines the exact value of shield effectiveness of Metal that was used in the Shield manufacturing , and also helps the designer to choose a new shield because it is plotting and compares between the values of the shield effectiveness for a number of metals to choose the best among them
