-Developed an object oriented physics simulator in C++, and Qt which builds on the existing simulator (KOSIA), to further extend capabilities-Contributed to the ongoing development of KOSIA, Kepler’s open-source satellite RF interference simulation tool-Performed interference analyses to support regulatory affairs with governing bodies and other satellite operators-Developed python tools for interfacing with ITU databases (IFIC and MFIR) to obtain relevant RF data

-Continuing design and simulation of the passive magnetic attitude control system-Ran simulations to analyze how different physical configurations would effect the systems performance (i.e. residual magnetic moment)-Currently writing a paper on the attitude control system design-Manage orbital analysis subteam, which involves allocating tasks to different team members and representing the subteam at systems meetings to collaborate on interdisciplinary problems with other teams-Present current design progress to the Canadian Space Agency at design reviews

Passive Magnetic Attitude Control Design-Implementing a full design of the attitude control system using hysteresis rods and permanent magnets-The permanent magnets will align the long axis of the body with that component of the Earth's magnetic field, to improve antenna performance (the antenna are located on the bottom, so this will cause the antenna to be in optimal position where they are parallel to the ground)-The hysteresis rods will dampen rotation about the other 2 rotational axes, so the satellite does not spin too fast and cause damage to the sensitive equipment-This needs to take into account environmental disturbance torques, like the gravity gradient and aerodynamic torques-This design is done mainly using MATLAB, with the aid of the Aerospace Toolbox (This is needed because quaternion math is used to work with the attitude calculations)-Data is taken from STK, such as the satellites coordinates, and the Earth's magnetic field strength's at various points in the orbit-This has been fully automated using the STK Connect commands in MATLAB, so a script can be ran which does the whole data collection process-The whole process has involved lots of research into other similar implementations, as well as the theory behind the quaternion math and other physical phenomenaPower generation:-Simulated solar power generation in orbit using STK (Systems Tool Kit)-Analyzed that data in MATLAB to estimate the orbital average power-This data was used in combination with thermal simulations from other sub teams to help make a design decision on the cube satellite's battery

-NSERC USRA Recipient for this work term-Worked Under Dr. Ray LaPierre-Presented a poster for the summer work at the McMaster USRA poster presentation day-Conducted a talk to around 40 students and professors about my summer researchThe main focus of this position was to develop a working simulation for a nanowire thermoelectric device using COMSOL Multiphysics. A preliminary part of this involved the design in CAD of the heaters. These heaters were patterned onto silicon wafers in the McMaster clean room (CEDT). This eventually led up to constructing a "nanowire functional unit" in COMSOL where the thermoelectric voltage, as well as the heat distribution could be studied.
