Abstract

LetSat is a 20-person undergraduate capstone design team at LeTourneau University. LetSat-1 is currently nearing the end of its preliminary design phase. The primary mission of LetSat-1 will be as a technology demonstrator for GPU-based artificial intelligence hardware. The primary component is a NVIDIA Tegra K1 general purpose GPU, with its associated peripherals. To utilize and demonstrate the capabilities of such a GPU, a novel navigation system is being developed. Using machine vision, the AI will analyze downward-looking photographs taken by an onboard camera to determine instantaneous orbital parameters. It is noted that such a scheme will work above any orbital body with permanent terrain, and it could easily be integrated into interplanetary spacecraft.
