'''Kalman Filter'''
'''Kalman Filter''' is an algorithm that takes in a bunch of noisy data from different sensors and uses knowledge of the dynamics of the system to predict the current state of the sattelite. It was invented in the early 60s to navigate people to the moon.
'''TortoiseSat''' is an experimental algorithm published by a Stanford lab a few months ago. It allows us to control our satellite using only magnet-torquers (small controlled current loops that create torque by interacting with Earth's magnetic field). The difficulty with this is that with magnet-torquers you can only generate a torque in two directions and not all three, which is why we need the experimental optimization algorithm to do it. We hope to demonstrate this algorithm on orbit for the first time with our satellite.
