AMSAT Fox-1 satellite Maximum Power Point Tracker hardware design files

The Fox-1 Maximum Power Point Tracker utilizes analog computing to track the solar panel voltage which generates the maximum amount of power from solar cells. It implements what is essentially a "temperature-based set-point constant voltage algorithm" MPPT. Since the solar cells are well-known, this design uses op-amps to compute the predicted voltage which will produce maximum power as fast as the analog bandwidth of the components used will allow it. Analog MPPT was chosen for it's "stateless" design due to radiation tolerance concerns of microcontrollers.
