SMiLE: Spun Microgravity Liquid Experiment

This project aims to carry out an experimental investigation into the dynamics of droplet production in a reduced gravity environment onboard the International Space Station (ISS). The experiment has been designed to interface with and occupy a 1U (11cm x 10cm x 10 cm) slot in the nano labs rack provided by NanoRacks. The investigation will focus on clearly identifying the dynamics of a newly identified drop formation process present in reduced gravity environments (akin to a dripping tap in reduced gravity). The experiment comprises a flow chamber (where the drops are formed and observed), a syringe pump to provide the flow, two control valves, two USB cameras and a microcontroller. The assembly is housed in a rotating drum, allowing the system to be spun and introducing a centrifugal force to separate the fluid from the air in the flow chamber. Flow rate control allows adjustment of fluidic parameters such as Reynolds and Weber number. Cameras monitor the fluid flow into the chamber and provide the principle data output. Outcomes from this investigation will be the experimental identification of the measure of the chaos present in this system and a refinement of the understanding of the transitions into and out of this flow regime. Applications of this work are relevant to industries that rely on drop on demand processes such as ink-jet, PCB, flexible electronics and genome printing.

QB50 - An International Network of 50 CubeSats

QB50 is a network 50 CubeSats that will be launched together in the first half of 2015 into a 'string-of-pearls' configuration in a circular orbit at 320 km altitude, inclination 79 degrees. These CubeSats will comprise a mix of atmospheric double CubeSats and double or triple CubeSats for science and technology demonstration. All atmospheric double CubeSats will carry a set of standardised sensors for multi-point, in-situ, long-duration measurements of key parameters and constituents in the largely unexplored lower thermosphere and ionosphere. These multi-point measurements will allow the separation of spatial and temporal variations. Due to atmospheric drag, the CubeSat orbits will decay and progressively lower and lower layers of the thermosphere/ionosphere will be explored without the need for on-board propulsion. The mission lifetime of individual CubeSats is estimated to be about three months.

Rapid Recovery from Radiation-induced Errors in Reconfigurable Hardware

This project aims to develop new methods for implementing satellite-based digital systems using reconfigurable hardware devices. The results aim to extend knowledge on the design of fault-tolerant systems and enable the use of off-the-shelf digital hardware in the implementation of satellite systems. The project aims to develop essential tools to assist in implementing fault-tolerant reconfigurable systems. These tools will be founded on the discovery of techniques needed for modifying a design into a form amenable to error recovery and for implementing the design in hardware. During the course of the project, these techniques will be demonstrated and tested in-orbit on the international QB50 CubeSat program.

Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation

Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. Building on from earlier work by University of New South Wales, University of Adelaide and GPSat Systems, this project aims to create a system for locating interference and spoofers to GNSS of any power in real time, providing layered monitoring and reactive mitigation solutions against interference and spoofing attacks.

Preliminary Parameters For An Experimental Payload For Tropospheric CO2 Measurement Using A Space-borne Lidar 6U Cubesat Platform

This project investigated the design of a nadir-pointing space-borne lidar system for Tropospheric CO2 concentration mapping. The payload had very strict sizing and mass constraints and must fit inside a 6U Cubesat satellite bus. The laser transmitter uses an Erbium doped fibre laser in a Master Oscillator Power Amplifier (MOPA) configuration. It consists of a tunable narrow-line CW laser of low power that produces the required narrow line shape and can be switched between on-line and off-line wavelengths. Pulses are passed through a number of erbium doped (or erbium-ytterbium doped) fibre power amplifier stages. These stages use large mode area fibres, which increase the Brillouin scattering threshold and hence the power that can be handled. The system requires approximately 30 W of electrical power, and pulse energies of 1mJ. Lasers that would meet the mission requirements are not commercially available, so a laser system would have to be developed specifically for this application. The detection of the very faint signals will be made using an InGaAsP single photon counting system, based on the use of avalanche photodiodes operated in Geiger mode. A 10 cm aperture telescope was used as both a transmitter and receiver telescope.

Using VSTAR model derived spectra, the minimum number of photons collected for meeting the selection criteria at the calculated CO2 sensitivity peak, is M = 2.67x106. Preliminary results show that for a 600 km, circular sun-synchronous orbit, the number of photons detected is significantly lower than the required minimum to meet the high spatial and temporal resolution requirements, so the mission as proposed was not feasible. Higher power and telescope settings will have to be considered for a successful mission. Other applications such measurements from a UAV platform could potentially be achieved using the proposed payload configuration.

Simulation of a High Performance Attitude Control System for a 6U CubeSat

The purpose of this project was to analyse the attitude control system of an 8kg 6U CubeSat, which is capable of delivering similar performance to a microsatellite weighing 100 kg, with a corresponding reduction in cost. Specifically, the mission was a small optical telescope.

The results indicate that it may be possible to meet the arc second pointing stability requirement. However, there are limitations with the proposed model that require further investigation such as the resolution of the reaction wheels. It appears that 8 bits is insufficient to match the satellites body rates over the imaging period of 7.5ms. Further modelling of these wheels, the attitude Kalman filter, and the noise model is required.
