IN THIS PAPER, STRUCTURE OF IDAS CANSAT THAT HAS BEEN DESIGNED, CONSTRUCTED AND TESTED IN IUST, IS PRESENTED. THIS PAPER INCLUDES A DESCRIPTION OF CANSAT MISSION, DESIGN OF MECHANICAL SUBSYSTEM, ELECTRONIC CIRCUITS, AND ALSO AN ANALYSIS OF PERFORMANCE ALGORITHMS. ONE OF THE SPECIAL FEATURES OF IDAS IS ITS VERY LIGHT WEIGHT IN COMPARISON WITH OTHER CONGENERS. THIS FEATURE LEADS TO A RELATIVELY COMPLEX DESIGN FOR MECHANICAL SUBSYSTEMS INCLUDING STRUCTURE, REACTION WHEEL AND PARACHUTE. A COMBINATION OF FREEWHEELING AND BALLS AND BOWL IDEAS HAS BEEN USED TO CONNECT THE PARACHUTE TO THE CANSAT STRUCTURE. THIS JOINT KEEPS THE CANSAT MOVEMENT PERPENDICULAR TO THE GROUND. THE PARACHUTE HAS BEEN DESIGNED FOR HIGH SAFETY MARGIN (IN WEIGHT AND SPEED), TO SATISFY THE EXPECTATIONS OF STABILITY ALONG WITH THE REACTION WHEEL. WITH THE STABILITY RESULTED, IMAGING WAS DONE WITHOUT ANY MECHANICAL DISTURBANCES AND WITH HIGH QUALITY. IN THE ELECTRONIC SUBSYSTEM, WE HAVE USED AN ARM MICROCONTROLLER TO CONTROL THE CAMERA. CAMERA’S DATA, DUE TO THEIR HIGH VOLUME, WERE STORED ON SD CARD AND SENT TO GROUND STATION IF NECESSARY. AS THE MICROCONTROLLER OPERATES IN HIGH CLOCK FREQUENCY, IT OFFERS CANSAT COMPLEX AND VARIED OPERATIONALLY SUCH AS RELEASE DETECTION AND DATA HANDLING. RELEASE DETECTION ALGORITHM IS SENSITIVE TO CANSAT ACCELERATION. THIS IS A NEW APPROACH AND REDUCES THE PROBABILITY OF FAULTY DETECTION. AFTER RELEASE, CANSAT TRIES TO ACHIEVE ITS GOAL AND TAKE PICTURES FROM GROUND WHILE READING, STORING AND SENDING THE SENSORS DATA TO THE GROUND STATION. TO VERIFY THESE FUNCTIONS, WE IMPLEMENTED SEVERAL TESTS AND EXPERIMENTS.

THIS ARTICLE DISCUSSES THE DETAILS AND CONSTRUCTIONS OF NOVEL BIO-PAYLOAD AND PHOTO CAPTURING CANSAT STRUCTURESWHICH HAVE BETTER EFFICIENCY INTHEIR SUBSYSTEMS SPECIALLYIN ELECTRICAL AND COMMUNICATIONAL SUBSYSTEMS. FOR IMPLEMENTING THIS SYSTEM DESIGNING, THESE CANSATS HAVE LIMITATIONS ON SIZE AND WEIGHT WHICH BIO-PAYLOAD CANSAT AND PHOTO CAPTURING CANSAT MUST BE UNDER 1.08 KG AND 0.35 KG IN WEIGHT, UNDER 66 AND 100 MM IN DIAGONALAND ALSO UNDER 115 AND 340 MM IN HEIGHT RESPECTIVELY. THUS THE SYSTEM IS SO SMALL AND NEEDS TO BEDESIGNED WELL TO PROVIDE SUBSYSTEMS CONDITIONS. IN THIS PAPER OPTIMUM CONSTRUCTION, CANCELLING AND PREVENTING FROM OCCURRING NOISES, COMMUNICATIONAL SUBSYSTEM AND ITS COMPONENTS, NOVEL BATTERY PLACEMENT AND NOVEL GRAPHICAL USER INTERFACE (GUI) WHICH IS THE HEART OF EARTH CONTROL STATION DESIGNED FOR BIO-PAYLOAD CANSAT, WILL BE DISCUSSED IN DETAILS. FIRST OF ALL WE DESCRIBE THE STRUCTURE WHICH HAS INNOVATIVE MODEL ON PREVENTING NOISES IN ELECTRICAL AND COMMUNICATIONAL SYSTEMSBY GIVING THEM THE APPROPRIATE PLACEMENT AND ALSO USING SHIELDING IN ELECTRICAL CIRCUITS SPECIALLY TO PREVENT FROM FLICKER AND THERMAL NOISES WHICH HAVE PROFOUND EFFECTS ON PCBS TRACKS, THEN IT IS DESCRIBED THE DIFFERENT COMMUNICATION SUBSYSTEMSECTIONS SUCH ASTRANSCEIVER MODULES, DATA ACQUISITION BOARD ANDEARTH STATIONWHICH ONE OF THE MOST IMPORTANT OF ITS DUTY IS ANALYZING AND CATEGORIZING EACH RECEIVING DATA FRAME.THESE NOVEL METHODS ANDFUNCTIONALITIESWERE USED TO MAKE DATA TRANSMITTING MORE ACCURATE AND SAFETY TO BE A SUCCESSFUL MODELTHAT CAN BE USED FOR CONSTRUCTING NEW AND DIFFERENT AEROSPACE SYSTEMS. ALSO THESE CANSATSSHOWS THEIRFABULOUS FUNCTIONALITY IN ACHIEVING FIRST AND THIRD RANKS IN THE FOURTH IRANIAN CANSATCOMPETITION.
