ELEC9764 Ground Segment and Satellite Operations
Assignment Term 1, 2024
In this assignment, you have been provided with the Two Line Elements for a satellite, as well as
the location of a ground station and a start time. Your task is to write MATLAB code that uses
MATLAB Toolboxes (such as the Aerospace Toolbox) to calculate satellite visibility and other related
quantities. The commented MATLAB source code forms part of the assignment. You are also
required to produce plots showing satellite positions, range-rates, Dopplers, etc.
1. Create some MATLAB code using the Toolboxes that are available in MATLAB 2021b or later
versions to determine the ‘satellite visibility intervals’ within 48 hours of the start time,
where a ‘satellite visibility interval’ means a time interval when the satellite is within sight
of the ground station. Produce a table showing the time intervals that the satellite is
visible. Select the longest time-interval or longest pass for the remaining parts of the
assignment.
2. For the longest pass, produce MATLAB code that calculates the azimuth and elevation of the
satellite as it passes over. Produce plots of azimuth and elevation for the satellite for that
pass. Also produce a plot showing the angular rate at which the satellite passes overhead
(i.e. at which rate would a high gain antenna need to rotate to keep the satellite within its
main beam).
