AERO4701: Space Engineering

Advanced Avionics System (University of Sydney)

This Unit of Study (UoS) aims to teach the fundamentals of avionics system for the spacecraft /aircraft fields. In particular the focus is on developing an understanding of:

The concept of avionics design from aerospace mission requirements;
The principle of avionics subsystem and their architectures;
Inertial navigation algorithms which provide information about the position, velocity and attitude of aerospace vehicles;
The concept of multi-sensor aided inertial navigation system, and how aiding sensors can be combined to errors in inertial navigation systems; and
The principles of various aiding systems including the Global Navigation Satellite System (GNSS), air-data system (ADS), star/sun/earth tracking sensors, magnetometers and their impact on aerospace navigation systems.

Assignments

Assignment 1 will focus on the development of inertial navigation equations based on inertial measurement data set.

pdf files:assign1.pdf
Data set:imu_pva.zip (IMU.txt, PVA.txt)

Assignment 2 focus on the implementation of GPS navigation based on pseudorange measurements.

pdf files: assign2.pdf
Data and M-file: assign2.zip
others: plot_azel.m (for sky plot) , Errata.pdf, GPS SPS signal specification.pdf
Note1) For Q.3 please use the true clock bias (RcvClockBias.mat)
Note2) Check the Summary for GPS processing (GPS_Summary.pdf)

Assignment 3 is to implement a real-time navigation system on the simulated spacecraft platform which has 3-axis degree-of-freedom.

Note) Due to lab-moving and safety issues, the rate-table can not be accessed. The third assignment is change to implement GPS/INS fusion filter.
