13SSTGHGSA: This project entitled «GHGSat-D ADCS Panning Mode» has the objective(s) : The primary objective of the project is the development of the ADCS Panning Mode of the GHGSat-D satellite with a planned launch date in the second half of 2015. ""Panning mode"" is a spacecraft attitude control mode that is required for GHGSat-D payload observations. Panning mode is similar to a ground target tracking mode in that both modes aim to control the spacecraft attitude with respect to fixed locations on the Earth's surface. In target tracking mode the aim is to keep the ground target stationary in the instrument field of view (“FOV”), ideally at the centre of the image. In Panning mode, the goal is to have the target pass through the FOV within a predefined duration, passing from one side of the image to the other while passing as close as possible to the centre of the FOV in the process. The University of Toronto Institute for Aerospace Studies – Space Flight Laboratory (“UTIAS-SFL”) will design and develop the panning mode; the design will then be simulated in a lab environment by UTIAS-SFL and Xiphos Systems Corporation (“Xiphos”) to attain TRL 4.
