An artificial satellite is a system engineered to transmit different information from space to a ground control station. It is not a single system of communication but is a combination of complex multiple subsystems, which constantly communicate within the satellite with each other. This type of communication is intra-satellite communication. Currently, most of the satellites utilize a wired harness to provide power and signal connections for intra satellite communication, which results in a heavier system integration. This paper takes the approach towards wireless communication within the satellite using Bluetooth module HC-05 between the attitude and orbit control system(AOCS), sensors and actuators. The paper's objective is to reduce the weight of the satellites launched into orbit, in order to provide fewer thrust requirements. The system is based on Arduino Mega2560 and Lpc2148 which are being considered as two modules for the subsystems of a satellite.
