The USB uplink handles voice, telecommand (low bandwidth), and ranging signals. The downlink handles voice, telemetry (lots, including astronaut biometrics) and either ranging or video. The ranging code system is quite interesting and is relevant to an understanding of GPS. It relies on the Chinese Number Theorem, which is also widely used in cryptography. Also […]

Abstract: A field-programmable gate array (FPGA) is an integrated circuit in which the logic and interconnections can be defined by downloading a bitstream to its memory. Since their  introduction in the 1980’s, these devices have dramatically increased in capacity and functionality, with the recent Xilinx ZU29DR FPGA integrating a 1.5 GHz Quad-core ARM Cortex-A53 processor; […]
