CubeSat model for image data transmission

Abstract

This work focuses on a design of nanosatellite and its communication system with use of solely Commercial OffThe-Shelf (COTS) parts. Aim is to construct an operational model according to CubeSat standard, capable of capturing and transmitting imagery along with telemetry. Satellite is expected to respond to ground station’s commands. Regulations constraining satellite from the point of orbital lifetime and usage of available spectrum are being discussed here. Also requirements for suitable frequency band and transmission itself are explained, providing downlink and uplink requirements for the RF circuitry. Except transceiver, attention was paid to on-board computer, camera and power system.
