Pleiades-Atlas is a 1U satellite which will act as a device in a small mesh network of 5 satellites each with the same bus design but unique payloads. These satellites aim to demonstrate a fault-tolerant method of communication using inexpensive custom-built subsystem PCBs and the amateur radio frequency bands.
Teralink-1 is a 6U satellite that will establish a sub-THz access Link (UL and DL) to/from Low Earth Orbit (LEO) to enable high-speed reliable communication between ground and space. This mission will do so by using a custom terahertz half-duplex radio which will interface with an in-house built ground station terahertz antenna.
The goal of this project was to provide a testbed that could be used to test an ADC system of a satellite (up to 12U in size). The Merritt coil is a more powerful version of the Helmholtz coil which can be used to generate uniform magnetic fields. One of the 3 axis is shown above.
This project grew out of my intrigue for the connection between analog and digital signals and how wireless communication works at its core. Then as I learned about computer architecture and high speed digital electronic integration, I became eager to implement an FPGA into a board.
This project helped me learn how to use a new PCB software. I essentially followed Phil's Labs tutorial on YouTube except I used Altium instead of KiCad.
