|Brief Handbook Description:||This UoS aims to teach students the fundamental principles and methods of designing solutions to estimation and control problems in aerospace engineering applications. Students will apply learned techniques in estimation and control theory to solving a wide range of different problems in engineering such as satellite orbit determination, orbit transfers, satellite attitude determination, satellite positioning systems and remote sensing. Students will learn to recognise and appreciate the coupling between the different elements within an estimation and control task, from a systems-theoretic perspective. Students will learn to use this system knowledge and basic design principles to design and test a solution to a given estimation task, with a focus on aerospace applications (such as satellite remote sensing).|

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.
|Attribute Development Method||Attribute Developed|
|Students will work on implementing solutions to estimation and control tasks involving the design of different algorithms and systems. Students will develop skills in analysing mission constraints and requirements in aerospace remote sensing missions and modelling how design choices influence how errors propagate through a system during inference tasks.||Design (Level 4)|
|Students will apply estimation and control design theory to a number of key problems in aerospace engineering such as satellite attitude and orbit determination systems, satellite remote sensing and mapping and orbit transfer.||Engineering/IT Specialisation (Level 5)|
|Students will develop expertise in the fundamental principles and applications of estimation methods including the use of linear and non-linear least squares approximations for various engineering tasks.||Maths/Science Methods and Tools (Level 4)|
|Students will be required to conduct their own literature search in studying past solutions to example problems and draw upon this knowledge during their own design process.||Information Seeking (Level 4)|
For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table.
Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.Engineering/IT Specialisation (Level 5)
Assignment: Assignment 1 will focus on satellite mission design, the simulation of satellite orbits and the determination of satellite orbit parameters from range and line-of-sight observations.
Assignment: Assignment 2 will focus on the application of least squares estimation with relation to the operation of GNSS.
Assignment: Assignment 3 will focus on integrating the elements of estimation, orbital mechanics and navigation systems learnt in the first part of the course towards the design and simulation of a complete solution to a given remote sensing task.
