Pointing analysis and fine pointing controller design for a CubeSat laser communication system

For any space mission, the communication subsystem is an indispensable part of the satellite that carries the payload. Traditionally, on-board antennas transmitting Radio Frequency (RF) waves to the receiver have been used. Nowadays, laser communications is becoming increasingly popular due to its potential to become a license-free, secure and...

A high-efficiency switch-mode amplitude modulator for class E power amplifiers in nano-satellites

This thesis describes the design, simulation and implementation of a supply modulator to be used in a VHF power amplifier on the Delfi-n3Xt nano-satellite. First, a set of specifications is defined that describe the required functionality. These are derived from earlier work on related systems and confirmed through discussions within the project...

OLFAR: A low frequency radio receiver for space applications

An entire front-end IC has been designed. This front-end is capable of receiving and amplifing galactic noise. The input frequency range can be digitially adjusted between 0.03 MHz and 30.0 MHz. In this frequency range it is expected that, by using correlation techniques, the H1 line caused by hydrogen in the early space, can be retrieved. This...
