In the past decade, ACSER has established a strong heritage in multi-sensor integration for land navigation as evidenced by its numerous high quality journal publications in this domain of research. Triggered by recent developments in vehicular safety, driverless vehicles, etc., ACSER has...Read more
The Australian Centre for Space Engineering Research (ACSER) builds on the established UNSW strengths of Satellite systems, satellite navigation, earth observation and hypersonics. In these areas, the Centre works closely with and acts as a bridge between the Schools of Electrical Engineering & Telecommunications, Civil & Environmental Engineering, Computer Science & Engineering, Mechanical & Manufacturing Engineering and UNSW Canberra.

Where individual GPS L1 signals are too weak to be detected, conventional detection and navigation methods will not be able to yield sufficient pseudoranges to produce navigation solutions. In this scenario, Collective Detection, which combines individual GPS L1 signals projected from the signal...Read more
Industrial partner Saber Astronautics has developed a tether for cubesats, nominally as a way of de-orbiting the cubesat. However, this tether produces a current which can be used as a sensor of the ionosphere, helping measure the state of space weather. There are very few in-place sensors of...Read more
GPS receivers have long used two antennas separated by a relatively long baseline to estimate attitude, i.e. “which way you’re facing”. There have been some, but not many, solutions to this problem that use only a single antenna. This project proposes to further investigate this problem, using a...Read more
ACSER is developing a range of satellite navigation receivers to operate in space. Most commonly, those receivers are used in low earth orbit, i.e. at heights of 100s of km, well below the 26000km high GPS satellites. This project looks at how satellites in higher orbits can use Global...Read more
When a satellite is separated from its launch vehicle, it “tumbles”. It takes some time for this tumbling to be brought under control, and during that period it may be difficult to establish the satellite’s position. GPS, for instance, in general cannot be used because the receiver cannot...Read more
Cubesats have become very popular recently, and many are already in low-earth orbit. Missions are beginning to be considered that are in higher orbits, or leave earth’s orbit all together. For missions such as these, communications will be a serious issue. Because of a cubesat’s small size, it...Read more
Driverless cars will be with us in the near future and so the infrastructure to support them must be developed urgently. Building on many years of ACSER/ SNAP/ UNSW work looking at how vehicular ad-hoc networks (VANETs) and Dedicated Short Range Communications (DSRC) can be used to provide...Read more
Companies recently established to mine asteroids propose an architecture where a constellation of spacecraft will be used to perform the exploration, mining and processing functions. Some craft will be flying “orbiting” the asteroid, while others will be on the asteroid surface. It is essential...Read more

Direct Simulation Monte Carlo Modelling using FPGAs The Direct Simulation Monte Carlo (DSMC) method is the most commonly used numerical method for computing rarefied flows, such as those experienced upon planetary entry of a spacecraft, or in very small-scale flows. Invented by Prof. Graham Bird...Read more
This project will be of interest to those who wish to engage in Space Science, particularly hypersonic research. The selected candidate will work on an ARC funded project exploring "Flow Separation Phenomena" which are critical in the design of spacecraft when they enter /re-enter Earth or...Read more
Designing and implementing software for space is challenging. Not only does the software has to be able to cater for various scenarios, but the software also has to undergo an enormous amount of software verification before it can be allowed to be used in space....Read more
Depending on GPS/GNSS without the capability of validating its accuracy and validity can produce catastrophic consequences. Current techniques to validate GNSS/GPS-based positioning are limited and produces a large confidence interval which would be inadequate for vehicular...Read more
ACSER have an active research topics on GNSS signal interference detection and localisation in collaboration with a local engineering company. We can also conduct real-life field experiments using multiple synchronised and calibrated phased array nodes. GNSS...Read more
Global Navigation Satellite System (GNSS) spoofing and meaconing is the act of deceiving nearby GNSS users of their true location by transmitting a stronger bogus signal. On the other hand, GNSS jamming is the act of denying nearby users from using GNSS to obtain positioning, navigation or...Read more
Intelligence, Surveillance, Reconnaissance (ISR), Electronic Warfare (EW), Space and Cyber” are the highest priority research and innovation streams for both the Defence Innovation Hub and the Next Generation Technology Fund in 2017/2018. High altitude sensor systems (HASS) represent an...Read more
