Design of SDR Simulation for Wireless Communication between Ground Station and CubeSat Implemented by LabVIEW

Abstract

One of the main requirements of any satellite is the ability to communicate with the ground station reliably by sending and receiving data. In this paper, a design and simulation of the communication system between Ground Control Station (GCS) and the CubeSat for transmitting and receiving the telemetry data is introduced. Two different protocols are used for communication which are: Simple Serial Protocol (SSP) for the physical connections and AX.25 for radio transmission. Furthermore, the error of the received data is checked by using the Cyclic Redundancy Check (CRC) technique. The communication subsystem is developed by using Software Defined Radio (SDR) transceiver to perform multi-modulation techniques such as ASK, FSK, BPSK, and QPSK. The system is implemented by using LabVIEW to verify the communication between CubeSat and GCS.
